[ ] Screen labels such as menu items, page titles, setting items, dialog titles and but- tons are indicated by square brackets [ ]. CURSOR (Bold characters) Bold characters within the text indicate operating key labels. Unless otherwise specified, “Windows” represents Win- dows 95, 98, Me, Widows NT4.0, Windows 2000, or Win- dows XP. Mouse operation terminology Click: Press and quickly release the left button of the mouse. Right-click: Press and quickly release the right button of the mouse. Double click: Quickly click the left button of the mouse twice. Drag: While holding down the left button of the mouse, move the mouse and then release the left button to deposit the chosen item in the desired position. Activate: Click on a window on the screen to activate that window. We define measurement tolerances in terms of f.s. (full scale) values, with the following meanings: f.s. (maximum display value or scale length) The maximum displayable value or scale length. This is usually the name of the currently selected range. In this instrument, the maximum displayable value is the range (V/div) times the number of divisions (20) on the vertical axis. Example: For the 1 V/div range, f.s. = 20 V Accuracy This instrument complies with CAT II safety requirements. This instrument’s input modules comply with CAT I or CAT II safety requirements. To ensure safe operation of measurement instruments, IEC 61010 establishes safety standards for vari- ous electrical environments, categorized as CAT I to CAT IV, and called measurement categories. These are defined as follows. CAT I: Secondary electrical circuits connected to an AC electrical outlet through a transformer or similar device. CAT II: Primary electrical circuits in equipment connected to an AC electrical outlet by a power cord (portable tools, household appliances, etc.) CAT III:Primary electrical circuits of heavy equipment (fixed installations) connected directly to the distribution panel, and feeders from the distribution panel to outlets. CAT IV:The circuit from the service drop to the service entrance, and to the power meter and primary over- current protection device (distribution panel). Higher-numbered categories correspond to electrical environments with greater momentary energy. So a measurement device designed for CAT III environments can endure greater momentary energy than a device designed for CAT II. Using a measurement instrument in an environment designated with a higher-numbered category than that for which the instrument is rated could result in a severe accident, and must be carefully avoided. Never use a CAT I measuring instrument in CAT II, III, or IV environments. The measurement categories comply with the Overvoltage Categories of the IEC60664 Standards. Measurement categories (Overvoltage categories) The applicable measurement category is determined by the input module being used. Refer to “Applicable Standards” in "Chapter 5 Specifications" in the Input Module Guide for the applicable measurement categories.

of the various functions. • Before using the instrument the first time, verify that it operates normally to ensure that the no damage occurred during storage or shipping. If you find any damage, contact your dealer or Hioki representative. • Before using the instrument, make sure that the insulation on the probes and connection cords is undamaged and that no bare conductors are improperly exposed. Using the instrument in such conditions could cause an electric shock, so contact your dealer or Hioki representative for replacements. Operating temperature and humidity: 0 to 40°C at 20 to 80% RH (non-conden- sating) However, the operating temperature range may depend on the options used. Temperature and humidity range for guaranteed accuracy: 23±5°C, 20 to 80%RH Operating Precautions Before Use Instrument Installation Operating Conditions Operating Temperature While changing the battery in the Model 9719 Memory Back- up Unit 10 to 40°C While using the Model 8995 A4 Printer Unit, 8995-01 A6 Printer Unit, 9716 FD Drive or 9718 HD Unit 5 to 40°C Model 9717 MO Unit 5 to 35°C Avoid the following locations that could cause an accident or damage to the instrument.

wards. • Vents must not be obstructed. At least 50 mm At least 50 mm spacing on all sides When using the optional printer, provide enough space for ejected recording paper or use the Model 220H Paper Winder (optional recording paper auto winder). Handling the Instrument • Do not allow the instrument to get wet, and do not take measurements with wet hands. This may cause an electric shock. • Never modify the instrument. Only Hioki service engineers should disas- semble or repair the instrument. Failure to observe these precautions may result in fire, electric shock, or injury. • To avoid damage to the instrument, protect it from physical shock when trans- porting and handling. Be especially careful to avoid physical shock from drop- ping. • Use the handle to carry the instrument. See "Chapter 2 Names and Functions of Parts" (⇒ p. 19) • When the Model 8958 16-Ch Scanner Unit is installed, do not lift up on the connector section of the unit. The connector section could be damaged. Handling the Cords and Probes • Avoid stepping on or pinching cables, which could damage the cable insula- tion. • To avoid breaking the cables and probes, do not bend or pull them. • To avoid damaging the power cord, grasp the plug, not the cord, when unplug- ging it from the power outlet. Use only the specified connection cables. Using a non-specified cable may result in incorrect measurements due to poor connection or other reasons.

measurement precautions, refer to the Input Module Guide. Before Connecting Before turning power on • Before turning the instrument on, make sure the supply voltage matches that indicated on the its power connector. Connection to an improper supply voltage may damage the instrument and present an electrical haz- ard. • To avoid electrical accidents and to maintain the safety specifications of this instrument, connect the power cord only to a 3-contact (two-conduc- tor + ground) outlet. Installing and removing input modules • To avoid electric shock accident, before removing or replacing an input module, confirm that the instrument is turned off and that the connection cords are disconnected. • The mounting screws must be firmly tightened or the input module may not perform to specifications, or may even fail. • To avoid the danger of electric shock, never operate the instrument with an input module removed. To use the instrument after removing an input module, install a blank panel over the opening of the removed module. Using an Optional Printer When the instrument is not to be used for a long time, or when transport- ing To avoid straining some parts of the printer, and to prevent dirt adhering to the print head, set the print head to its lowered position (so that the print head rests against the print roller). After storing the printer without use for a long time, inspect the following before use: 1. Move the head raising lever up and down. 2. Perform test printing (printer check) three or four times. When printing • Avoid slow printing as much as possible in hot or humid environments. Other- wise, printer life may be severely shortened. • Please use only the specified recording paper. Using non-specified paper may not only result in faulty printing, but printing may become impossible. • If the recording paper is skewed on the roller, paper jams may occur. If the recording paper is skewed on the roller, paper jams may result. • Printing is not possible when the recording paper is loaded upside-down. Refer to "3.3 Loading Recording Paper (With a Printer Module Installed)" (⇒ p. 42) for printing precautions.

The maximum input voltage and maximum rated voltage to ground (between the grounds of the input terminals and the instrument, and between inputs of other analog modules) of each input module and exter- nal input terminals are shown below. To avoid risk of electric shock and damage to the instrument, be careful to not exceed these ratings.

42 Printing is available using the following optional printer (specified when ordering the instrument) and recording paper. About the Printer Recording Paper Usage Precautions 3.3 Loading Recording Paper (With a Printer Module Installed) Printer Recording Paper (size) Model 8995 A4 Printer Unit Model 9231 Recording Paper (A4 size) Model 8995-01 A6 Printer Unit Model 9234 Recording Paper (A6 size) The print head and surrounding metal parts of the Model 8995-01 A6 Printer Unit can become hot. Be careful to avoid touching these parts. When the instrument is not to be used for a long time, or when transport- ing To avoid straining some parts of the printer, and to prevent dirt adhering to the print head, set the print head to its lowered position (so that the print head rests against the print roller). After storing the printer without use for a long time, inspect the following before use: 1. Move the head raising lever up and down. 2. Perform test printing (printer check) three or four times. • Please use only the specified recording paper. Using non-specified paper may not only result in faulty printing, but printing may become impossible. • If the recording paper is skewed on the roller, paper jams may result. • Printing is not possible if the front and back of the recording paper are reversed. • Always use the paper cutter on the printer’s cover to cut the printed paper. Excessive paper dust can accumulate on the roller if the paper is cut by the print head. Handling and Storing Recording Paper The recording paper is thermally and chemically sensitized. Observe the follow- ing precautions to avoid paper discoloration and fading. Avoid exposure to direct sunlight. Do not store thermal paper above 40°C or 90% RH. Avoid stacking with wet Diazo copy paper. Avoid exposure to vola- tile organic solvents like alcohol, ethers and ke- tones. Avoid contact with ad- hesive tapes like soft vi- nyl chloride and cellophane tape.

Cleaning the Air Filters 7.2 Cleaning • To clean the instrument and input modules, wipe it gently with a soft cloth moistened with water or mild detergent. Never use solvents such as benzene, alcohol, acetone, ether, ketones, thinners or gasoline, as they can deform and discolor the case. • Wipe the LCD gently with a soft, dry cloth. Air filters are installed in the bottom panel of the instrument. Clean them periodi- cally before severe dust buildup occurs. If a filter becomes clogged, the instru- ment’s internal cooling is impeded, and damage may result. Also, be sure to thoroughly dry the filters before reinstalling. Operating with a wet filter may cause damage. 1 Turn the instrument off. 2 Place the instrument with the front upwards, and remove the filter covers from the bottom panel. 3 Remove the filters from the filter covers. 4 Use a vacuum cleaner to remove any dust or grime from the filters. If dust remains, wash with diluted detergent and dry completely. 5 Replace the filters in their covers, and reinstall. Filter Covers Instrument’s Bottom Panel Filter Filter Cover For instruments installed with filter covers For instruments installed with metal filters 1 Turn the instrument off. 2 Place the instrument with the front upwards. 3 Use a vacuum cleaner to remove any dust or grime from the filters.

Normally, no maintenance is required. However, depending on usage conditions, dirt and paper dust may accumulate on the thermal head over the long term, causing light or smeared printing. In this case, clean the head by the following procedure. 1 Use the CURSOR keys to move the cursor to the Function menu, and press the F7 [System] key. The System screen appears. 2 Press the SUB MENU keys to select the [Init] menu item. The Init (Initialization) Settings screen appears. 3 Use the CURSOR keys to move the cursor to the [Printer Check] button, and press the F1 [Execute] key. The [Printer Check] dialog appears. 4 Move the cursor to [Cleaning], and press the F1 key. The paper should print solid (100%) black. Check for any smearing. If sufficient improvement is not obtained even after cleaning several times, wash the print head (⇒ p. 86). Self-Check Cleaning Function Menu Before Cleaning Recording paper is required to clean the print head. Verify that the recording paper is loaded correctly. 1 2 3 4

If the front side is moistened, it becomes discolored. 2 Lower the head-raising lever, and wash the head by sliding the paper back and forth. Back Side of Printing Paper Washing the Print Head Be careful not to apply too much undiluted alco- hol. About the Print Head To avoid discoloring or deforming the instrument, observe the following precau- tions: • Do not use organic solvents such as thinner or benzene • After washing, allow the printer to dry completely before use. About the Roller Surface • White powder such as paper dust may accumulate on the roller surface after long-term use. A small amount should have no effect on printing, but can be removed with a commonly available camera blower brush if it causes concern. • Always use the paper cutter on the printer’s cover to cut the printed paper. Excessive paper dust can accumulate on the roller if the paper is cut by the print head.

A2 Appendix 2 Overview of Settings and Functions Instrument Settings About the Screen The instrument’s LCD provides SVGA (800 × 600) resolution. The wave- form display area consists of 625 horizontal dots and 500 vertical dots. The waveform display area is divided into 25 divisions horizontally, and 20 divisions vertically, with each division composed of 25 dots horizon- tally and vertically. Each data frame (one division) represents 100 samples horizontally, and 80 to 1600 data bits vertically. (depending on the input module) Each displayed data frame (one division) changes in accordance with expansion and compression of the time and voltage axes. 25 div 20 div 1 div = 100 samples Setting the Timebase (Horizontal Axis) See "4.2.2 Setting the Timebase (Horizontal Axis) and Sampling Rate", "8.9 Magnifying and Compressing Waveforms", and "Appendix 4.3 Measurement Frequency Limit" in the Instruction Manual The input signal acquisition rate corresponds to time per division on the horizontal axis. Determining the timebase: Calculate from the frequency and period. f [Hz] = 1/t [s] (f: frequency, t: period) Example: If the measurement frequency is 50 Hz: 50 [Hz] = 1/t [s] t = 1/50 [s] = 0.02 [s] = 20 [ms] So to display five cycles on the screen (25 divisions horizontally), 20 [ms] × 5/25 [div] = 4 ms/div Select 5 ms/div for the timebase, which is the closest available setting to the calculated value. To measure phenomena with relatively fast signals such as instantaneous waveforms, we suggest setting a small value (if the frequency is 50 Hz, the timebase should be set faster than 5 ms/div). During and after measurement, waveforms can be expanded and compressed along the time axis. 1 div Timebase: with 1 div = 5 ms • To expand and compress: Change the expansion and compression ratio. (⇒ p. 62) • To expand a specified section (Memory function only): Use the Zoom function. (⇒ p. 62) Timebase: with 1 div = 10 ms Timebase and Sampling See "Appendix 4.1 Sampling" and "Appendix 4.4 Recorder Function Values" in the Instruction Manual For the Memory Function (Sampling point recording): The sampling period is 1/100th of the timebase. When the timebase is set to 100 µs/ div, the sampling period is 1 µs. Changing the timebase setting also changes the sampling period accordingly. For the Recorder Function (Envelope recording): One data point is recorded every 1/100th of the timebase as two amplitude values: the maximum and minimum values measured during the specified sampling period. With the 10 ms/div timebase, one data point is recorded every 100 µs. When the sampling period is set to 1 µs, 100 samples are provided in order to record each data point. The values recorded for each data point are maximum and minimum values among these 100 samples. Maximum Minimum 1 div 1 2.... ....100 Sampling Period Sampling Points

A3 Recording Length Setting See "4.2.4 Setting the Recording Length (number of divisions)" in the Instruction Manual Set the length (number of divisions) to record each time data is acquired. Each division of the recording length consists of 100 data points. The number of data points of the whole recording length is the specified recording length (divisions) × 100, + 1. Example. The number of data points when the specified recording length is 50 divisions: 50 div × 100 data points + 1 = 5001 data points Measurement Range Setting See "Chapter 3 Input Channel Settings" in the Input Module Guide Select the amplitude range for measurement. The setting value is the number of units per division on the vertical axis. About Resolution (per vertical division) Measurement resolution depends on the particular input module. (with x1 voltage axis magnification) Input Modules Resolution (bits/div) Screen Full Scale (bits) Minimum Resolution 8936 to 8940, 8946, 8947, 8959 80 1600 5 V/80 = 62.5 mV * 8956 100 2000 5 V/100 = 50 mV * 8957, 8960 8958 [Voltage] Mode 1600 32000 5 V/1600 = 3.125 mV* 8958 [Temp] Mode 1000 20000 10°C/DIV = 0.01°C * When measurement range is 5 V/div With 1 V/div range (10 Vp-p input) With 500 mV/div range (10 Vp-p input) 0V 1 div 20 div More about Measurement Range and Resolution: "Chapter 5 Specifications" in the Input Module Guide • To expand and compress: Change magnification of the vertical axis. ("8.9 Magnifying and Compressing Wave- forms" of the Instruction Manual) • To shift the position on the vertical axis: Change the zero position. ("7.1.2 Setting the Waveform Display Posi- tion (Zero Position)" of the Instruction Manual) • To display converted units: Use the Scaling function. ("5.4 Converting Input Values (Scaling Function)" of the Instruction Manual) • To freely set the display area of the vertical axis: Use the Variable function. ("8.9 Magnifying and Compressing Waveforms" of the Instruction Manual) About Trigger and Pre-Trigger Recording See "Chapter 6 Trigger Settings" in the Instruction Manual When recording a specific signal with recording criteria (trigger criteria) set, the waveform can be recorded only when the trigger event occurs. To view phenomena prior to the trigger event, set the Pre-Trigger value to the amount of data your want to record before the event occurs. Example: When the recording length is set to 1000 div and Pre-Trigger is set to 5% The pre-trigger recording length (data points) is 1000 div × 5% = 50 div (5000 data points).

To record and search for waveform anomalies: Trigger Function and Waveform Search Function See "Chapter 6 Trigger Settings", "8.14 Searching a Waveform" in the Instruction Manual Trigger signals can be generally be obtained from the following sources: An- alog trigger, logic trigger, external trigger, timer trigger and forced (manual) trigger. A trigger can be applied as a result of one or a combination of these criteria, except for the Manual trigger. Also, after measurement, any waveform can be searched and displayed us- ing the Search function.

A7 Read this when you want to perform a certain task, or when the procedure for a particular operation is unknown. Refer to "7.1 Troubleshooting" (⇒ p. 81) if the display or operation seems abnormal, or if damage is suspected. Appendix 3 Common Questions To Perform This Measurement In this case Description Reference Perform simultaneous mea- surements with different sam- pling rates Set different sampling rates on Timebase 1 and Time- base 2 from the Status screen of the Memory function, where Timebase 1 or Timebase 2 can be selected for each channel. "4.2.3 Setting Different Sam- pling Rates" in the Instruction Manual To send a warning when an anomaly occurs When a trigger is applied, a signal can be output from the External I/O terminals. "14.2.2 Trigger Output (TRIG OUT/CAL)" in the Instruction Manual To use multiple recorders Recording with multiple instruments can be performed using the external control connectors. "14.2.1 External Trigger Input (EXT TRIG)" and "14.2.2 Trig- ger Output (TRIG OUT/CAL)" in the Instruction Manual What happens to measure- ment data when power to the instrument is lost during mea- surement? Measurement data acquired prior to the power interrup- tion is lost. When [Auto-Resume] is enabled from the Environment Settings Screen of the System Screen, recording resumes automatically when power is restored. How- ever, this action differs according to trigger settings. (Default setting: [Off]) "12.2.2 Using the Auto-Resume Function (Resume After Power Restoration)" in the Instruction Manual To measure shock when dropping a test object, and to search for the vibration reso- nance point. Use an acceleration sensor with the Model 8947 Charge Unit to measure vibration and shock. To record actual effective (true RMS) values of mains voltage True RMS values can be recorded using the Model 8959 DC/RMS Unit. To record anomalous waveforms, enable level triggering to acquire waveforms when the RMS voltage drops. Example. Trigger: Level, Level: 90 V, Slope: ↓ (Falling) To monitor 120 V (50 or 60 Hz) power for a drop to 80% or lower Using a voltage measuring input module, enable trigger- ing upon voltage sag. To observe instantaneous power dropouts on 120 V (50 or 60 Hz) commercial mains, and the internal voltages of affected devices. Measurements can be made by the combination of a voltage measuring input module and a clamp with con- nection cable. Changes in commercial power, changes in internal voltage of devices and changes in current flow to devices (using a clamp-on sensor) at the instant of power dropout are recorded on separate channels, and analyzed. By splitting the screen, power and device-volt- age waveforms can be displayed in separate traces. Split-Screen Display: "7.2.1 Assigning Display Data to Sheets" in the Instruction Manual To observe surge noise on 240 V (60 Hz) AC mains. AC mains and surge waveforms can be measured simul- taneously. Surge noise can be detected by the slope trig- ger. Acquired waveforms can be analyzed by expansion and zooming.

A8 To observe the voltage wave- form on 600 V power lines Use a voltage measuring input module and the Model 9322 Differential Probe or Model 9665 (10:1) or 9666 (100:1) attenuating probes. "2.4 Connecting a Differential Probe", "2.5 Connecting Atten- uating Probes", and "3.10.15 Probe Attenuation Selection" in the Input Module Guide To perform frequency analy- sis Measure using the FFT function. We recommend using an input module equipped with an anti-aliasing filter func- tion (Models 8938, 8947, 8957 and 8960). "Chapter 3 FFT Function" in the Analysis Supplement To record data without gaps, or over a long term Measure using the Real-Time Saving function. With the Memory and Recorder functions, data is saved after each recording length, causing measurement to be interrupted. With the Real-Time Saving function, data can be stored continuously without gaps. "Chapter 9 Measuring with Real-Time Saving" in the In- struction Manual In this case Description Reference Related Settings In this case Description Reference What is the basic setting pro- cedure in order to view a waveform? To display a waveform, set the following: (1) timebase (horizontal), (2) voltage axis range and zero position (vertical), and (3) trigger [Off]. To use automatic setting for measuring when the time- base and the measurement range are unknown Press the FUNCTION MODE key to select the FN mode on the Waveform screen (DISP key), and select F4 (Auto Setup). The proper range is selected automatically, and record- ing starts. Make other settings as occasion demands. "3.3.5 Automatic Range Setting (Auto-Ranging Function)" in the Instruction Manual To set up simply when the measurement configuration is already determined Measurement configuration settings can be saved to storage media as an auto-setup file (STARTUP.SET), so the settings can be loaded automatically at power-on. (Auto-Setup Function) Also, the settings data can be save to the instrument and it can be automatically loaded. "10.3.6 Saving Settings Data", "10.5 Saving & Loading Auto Settings File (Auto Setup Func- tion)" in the Instruction Manual What happens to measure- ment configuration settings when power is turned off? When power is turned off, measurement configuration settings are preserved within the instrument. When power is turned back on, those measurement configura- tion settings are recalled. "3.6 Turning the Power On and Off" (⇒ p. 46) in this manual What is the longest possible recording length with the fast- est timebase setting? Recording time is determined by the [Shot]. The fastest available timebase setting is [5 µs/div]. The recording length can be increased by optional internal memory expansion and by limiting which channels are used, so the maximum time cannot be definitively specified. A recording length of 10,000 divisions at 5 µs/div is equivalent to 0.05 seconds recording time. "4.2.4 Setting the Recording Length (number of divisions)" in the Instruction Manual To observe phenomena such as waveform anomalies prior to a trigger event From the Trigger Settings screen, enable Pre-Trigger recording. (Set the position of the trigger point as a per- centage of the recording length, where 0% represents the recording start point and 100% represents the recording end point) "6.5 Pre-Trigger Settings" in the Instruction Manual If “Storage Off” appears Verify that an input module is installed for the selected channel. If installed: On the Status Settings screen, verify that the channel to be used for measurement is enabled [On]. If not installed: Select an installed module. "4.2.1 Selecting Channels to Use" in the Instruction Manual

A9 How long will recording con- tinue when the recording length is set to [Cont] with the Recorder function? When trigger criteria are met, recording starts and con- tinues until you press the STOP key. Up to 5,000 divi- sions of data (with Model 9715 Memory Board installed) from measurements prior to the stopping of recording is retained in internal memory. When Auto Print or Auto Save is enabled, the data ac- quired by the instrument is printed or saved on each such occasion. About memory capacity and re- cording length: "4.2.4 Setting the Recording Length (number of divisions)"; "Setting Continuous Recording (Cont)" in the Instruction Manual What is the difference between the Memory and Recorder functions? Which function is selected determines how the timebase is set. The sampling method for each function is also dif- ferent. Because the purpose of the Memory function is acquisi- tion of instantaneous waveforms, if you set a slow time- base for long-term recording, the sampling period may be unsatisfactorily lengthened. On the other hand, the Recorder function samples and records maximum and minimum values at the specified sampling rate regard- less of the timebase setting. As a result, however, only slow timebase settings are available.
