YOKOGAWA CA310 Manuals

User's Manual Safety Precautions The handling precautions, component names, and specifications are covered in the separate Getting Started Guide (IM CA310-02EN). Be sure to read the Getting Started Guide before using this instrument. Basic Setup 1. Turn the instrument on, and set the rotary switch to SETTING. 2. Use the left-most up and down keys to select the setting and the right-most up and down keys to switch the options. 3. Press OUTPUT ON/OFF to confirm the setting. ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ POWER Selects the setting Selects an option Confirms the settings Setting Auto power-off Backlight Sweep time HART/BRAIN Communication resistance Initialization of span settings Initialization of settings Options ON*/OFF ON/OFF*/TIMER 15s*/30s/45s/60s ON/OFF* — — Display *: Default value OUTPUT ON/OFF Auto power-off If this is set to ON when the instrument is running on batteries, the power automatically turns off if you do not operate the instrument for approx. 20 minutes. This is invalid when the instrument is running off of the AC adapter. Backlight Turns the backlight on and off. If set to Timer, the backlight turns on for approx. 2 minutes every time you operate a key. Sweep time When sweeping in steps, set the output duration of each step. When sweeping linearly, set the output duration for the value to change from 0% to 100%. HART/BRAIN communication resistance If you want to connect the 250 Ω communication load resistance to a HART or BRAIN communication system, turn this on. Initialization of Span Settings Initializes the span settings. Initialization of Settings Initializes settings. Measurement WARNING • Always turn off the power of the device under measurement before connecting it. Connecting or disconnecting lead cables without turning off the device under measurement is extremely dangerous. • Do not connect current circuits to the voltage input terminals. Likewise, do not connect voltage circuits to the current input terminals. Improper connection may cause electric shock or burns or may damage the device under measurement or the instrument. French AVERTISSEMENT Avant de brancher l’appareil à mesurer, mettez-le hors tension. Il peut être très dangereux de brancher/débrancher les câbles de mesure sans mettre l’appareil à mesurer hors tension. Évitez en particulier de brancher un circuit de courant sur les bornes d’entrée de tension ou un circuit de tension sur les bornes d’entrée de courant. Un branchement inadéquat risquerait non seulement d’endommager le circuit ou l’appareil à mesurer ainsi que l’équipement, mais il pourrait également représenter un risque pour les personnes. 1. Set the CA310’s measure/source switch to MEASURE. 2. Follow the instructions in the Getting Started Guide to connect the CA310 to the device to be measured using the included lead cable. 3. Use the rotary switch to set the range. In measurement mode, mA SIMULATE is invalid. 4. Turn on the device to be measured. The measurement appears on the CA310. This manual explains how to use the Volt mA Calibrator. Keep this manual in a safe place for quick reference in the event that a question arises. LOOP POWER Apply a constant 24 VDC voltage to the transmitter to perform a loop test. The displayed value is current. Set the rotary switch to LOOP POWER and take measurements. Press OUTPUT ON/OFF. 24 VDC voltage is applied. Press OUTPUT ON/OFF again to stop the application. 4-20mA + — Two-wire transmitter Distributor + — HART Communicator Sourcing 1. Set the CA310’s measure/source switch to SOURCE. 2. Follow the instructions in the Getting Started Guide to connect the CA310 to the target device using the included lead cable. 3. Use the rotary switch to set the range. In source mode, LOOP POWER, 50 mA, and 50 V are invalid. 4. Follow the instructions for common operations in the Getting Started Guide, and set the output value with the ▼ and ▲ keys. 5. Press OUTPUT ON/OFF. ON appears on the screen, and the output is turned on. Press OUTPUT ON/OFF again to turn off the output. If you change the range, the output turns off. Note • If the load current in a voltage range or load voltage in a current range exceeds the maximum value in the specifications, the protection limiter is activated, and the output is turned off. To restore, set the load back to a normal condition, and press OUTPUT ON/OFF again. • The CA310 is calibrated excluding the voltage dip in the lead cable. Load current readings include an error resulting from the lead cable resistance. mA SIMULATE If the range is set to mA SIMULATE, the CA310 operates as a two-wire transmitter simulator and sinks current applied to the Hi terminal from an external voltage source (distributor). 4-20mA + — Two-wire transmitter Distributor + — Changing the Output Mode 1. Refer to “Keys” in the Getting Started Guide, and set the output mode. Normal output (no display): The set value is output. The output value can be varied using the ▼ and ▲ keys. Span check ( ): In addition to normal output, the output can be varied in units of 25% of the span. Step sweep( ): The output is varied automatically in steps of 25% of the span. Linear sweep ( ): The output is varied linearly from 0% to 100%. ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ Press simultaneously to set the output mode. Pauses or resumes sweeping Output setting for span check ▲ ▲ ▲ ▲ ▲ ▲ ▲ ▲ Increase or decrease by 1 count Increase or decrease by 100 counts Increase or decrease in 25% steps of span Set to 100% of span Set to 0% of span Pressing this when sweeping is stopped or paused sets the output to the span 0% value. Sweeping The output value is varied automatically between 0% and 100% of the specified span. There are two sweep modes: step and linear. Time Output 0% 100% Sweep time Time Output 0% 100% Sweep time Step sweep Linear sweep 1. Set the 0% and 100% of the span, which is the sweep range. Set the span 0% value using the ▼ and ▲ keys and then press simultaneously the first and the second ▼ keys from the right. SET is displayed, and 0% is set. Likewise, set the span 100% value using the ▼ and ▲ keys and then press simultaneously the first and the second ▼ keys from the right. For details on key operation, see “Keys” in the Getting Started Guide. 2. Set the output mode to step sweep or linear sweep. 3. Press OUTPUT ON/OFF. Sweeping will start. Pressing OUTPUT ON/OFF again stops sweeping and also the output. Pressing OUTPUT ON/OFF yet again resumes sweeping from the last output value. Pressing the left-most ▼ key while sweeping pauses sweeping. The displayed value continues to be output while sweeping is paused. Pressing the ▼ key again resumes sweeping. When sweeping is stopped or paused, pressing the left-most ▲ key sets the output to the span 0% value.
