PN 0019408001A 12/2018 EN EN 2. Short Overview 2. Short Overview The CPD8500 digital deadweight tester is a digital primary pressure standard, which combines the metrological performances of traditional deadweight testers with the convenience of digital interface and transfer standards. It can be used to calibrate a variety of precision pressure devices such as pressure controllers, calibrators, indicators and transducers in either absolute or gauge pressure modes. The CPD8500 has two different chassis and multiple head options to cover absolute and gauge pressure types with a high accuracy class. The optional internal or external barometer allows easy zeroing and pressure type emulation. The CPD8500 digital deadweight tester’s measuring principle lies in the fundamental equation defining pressure: P = F / A It is based on the connection of a piston-cylinder assembly, whose surface area A is perfectly known, with a high accuracy electronic measuring cell, which measures the force F. Pressure is applied on the piston, which turns it linearly into a perfectly proportional force that is transferred to the measuring cell. The measuring cell permanently measures the pressure-generated force. It uses the force applied and creates an imbalance in a magnetic field. The electrical power generated to restore the magnetic field’s balance is interpreted by a microprocessor to display a stable pressure value. Figure 2.1 CPD8500 Gauge Version 2.1 Features Here is a short list of significant features designed into the CPC8500: ■ Highly accurate and linear internal load cell for mass measurement with zero and span adjustment capability ■ Operating pressure range from 0… 500 bar gauge (0 … 7,250 psi) and 0 .... 20 bar absolute (290 psi) ■ 50 ppm measurement accuracy ■ Interchangeable measuring heads CPS8500 for maximum accuracy and resolution ■ Removable environmental monitoring module for accurate ambient pressure, temperature and humidity feedback ■ An optional removable / interchangeable internal high accuracy barometric reference transducer providing absolute pressure emulation for gauge ranges ■ 7” color LCD with touch screen ■ Support for multiple head configurations on one chassis ■ Multiple languages; change the language for on-screen text and number/date formats by simply touching one of the “national flag” icons available in the setup screen. ■ Desk top ■ Easy level adjustment

PN 0019408001A 12/2018 EN EN 2. Short overview 2.2 Components 2.2.1 Base The base is composed of: ■ The measuring load cell, which measures the force applied by the head ■ The Environmental Monitoring Module ■ The electronic assembly which ensures stable pressure calculation, the display as well as remote communication ■ Optional internal barometric reference for pressure emulation ■ Precision vacuum sensor (absolute base only) for detection of stable vacuum pressure ■ The lubrication valves to automatically switch the lubrication circuit of the measuring head from atmospheric pressure to the measured pressure 2.2.2 CPS8500 Measuring Head The measuring head CPS8500 is designed for containing, operating and protecting the piston-cylinder assembly. The measuring heads are designed to operate with pure gas with the piston cylinder being lubricated with gas only for absolute versions and gas or oil (depending on the range) for gauge versions. The measuring heads are available in various versions: ■ Model 610 - absolute head ■ Model 110 - low pressure gauge head ■ Model 111 - medium pressure gauge head ■ Model 410 - high pressure gauge head Each measuring head is characterized by a nominal coefficient, Kn. This is a conversion factor specific to each measuring head, representing the pressure value per kilogram converted in proportion to the head’s cross sectional area. This conversion factor is either represented in bar/ kg or psi/kg. 2.2.3 Environmental Monitoring Module The Environmental Monitoring Module (EMM) accurately detects the ambient conditions and provide feedback to the electronic assembly inside the Base for easy adaptation of measurements corresponding to any changes in ambient conditions. The EMM consists of an ambient pressure, temperature and relative humidity sensor. The EMM continuously monitors the change in ambient conditions in real time. Whenever these conditions vary in proportions that might noticeably alter the measuring performance, the CPD8500 recommends the user to perform a span calibration for the internal load cell, this is explained in section 6.4.1.4. 2.2.4 Drive Motor Stable pressure measurement requires the piston-cylinder assembly inside the measuring head to spin at a fixed rate. The CPD8500 supports either a brushed DC or a brushless DC motor. 2.3 Turning On Apply power to the power connector on the rear of the base of the instrument with the included power cord, remove any plastic plugs from the rear panel pressure ports, and press the power switch to ON. The system will go through an initialization process, which takes about 1 minute, and then a display will appear similar to the screen shown below. Power Switch ON/ OFF Figure 2.2

When the units button is pressed a selection of imperial and metric units will be displayed on the right (Figure 6.4.1.2-A). The units menu is categorized by Imperial and Metric units. Further pressure units of each category can be navigated by the page forward [ ] and backward [ ] keys. The current pressure type is displayed by the Pressure Type button in the Home App. When an optional internal/ external barometric reference is installed, the native gauge instrument can emulate absolute pressure using the barometric reference. However for a native absolute instrument with an absolute base and an absolute head, the instrument can work in either gauge or absolute mode depending on the rear panel reference port connection. If the pressure reference port is left open to the atmosphere, the instrument measures gauge pressure, alternatively if the reference port is connected to a vacuum pump, the instrument can only measure absolute pressures. Both emulation and native pressure type can be activated simply by pressing the Pressure Type button. The emulation pressure type is highlighted in gold to distinguish from the native mode (Figure 6.4.1.2-B) Pressure Units button Figure 6.4.1.2-A Pressure units Pressure Type button Figure 6.4.1.2-B Pressure Type (Emulated) 6.4.1.3 Zero The Zero button [ ] in the Home App allows the user to perform a single point calibration to adjust the zero point of the internal load cell of the instrument. The Zero calibration must be performed, if after power up, the user notices a slight drift. This drift can be attributed to a variety of reasons like temperature drifts, changes in ambient conditions, changes in leveling of the instrument and/or its location. Table 6.4.1.4 displays different scenarios requiring Zero and Span calibration. The procedure for performing the Zero calibration is different for absolute and gauge mode. Figure 6.4.1.3 shows the Zero button in the Home App. Zero button Figure 6.4.1.3 Zero Button

PN 0019408001A 12/2018 EN EN 6. Operation WARNING! In order to obtain accurate pressure measurements, the user must check that the display indicates stable zero, before starting any measurements. 6.4.1.3.1 Zeroing in Gauge Mode or Emulated Gauge Mode This procedure is valid only when the pressure type of the instrument is set to Gauge. This can be done for following combinations in the instrument: ■ A gauge base with a gauge head ■ An absolute base with an absolute head with vacuum reference ports open to atmosphere. ■ An absolute base with a gauge adapted absolute head Pressing the Zero button initiates a zeroing sequence as shown by Figure 6.4.1.3.1. The current pressure reading turns gray during the process to indicate a non valid pressure reading. The status of the zeroing sequence is displayed on the right side of the screen. During the zeroing sequence, the status icon represents that the load cell is busy. Figure 6.4.1.3.1 Zeroing in Gauge Mode 6.4.1.3.2 Zeroing in Absolute Mode This procedure is valid only when the pressure type of the instrument is set to Absolute. This can be done when an absolute head is installed on an absolute base and the operation is carried out in native pressure mode. The Zero button is inaccessible (grayed) until a stable vacuum pressure is applied on the reference of the instrument and the vacuum sensor displays a value less than 20 pascals and greater than 2 pascals. Vacuum pump recommendations and connections are mentioned in Section 5. Zero button inaccessible Figure 6.4.1.3.2 Inaccessible Zero Button

PN 0019408001A 12/2018 EN EN 6. Operation 6.4.1.4 Span The Span button [ ] in the Home App allows the user to perform a single point calibration to adjust the span of the internal load cell of the instrument. The span calibration process loads a calibration mass located inside the instrument on the load cell to readjust the span of the cell. Figure 6.4.1.4-B shows the Span button turns orange [ ] when the Environmental Monitoring Module detects a change in the environment conditions outside the preset tolerance values. In this event, the user must perform the Span calibration by pressing the Span button. The status of the Span sequence can not be interrupted and the status of the process can be seen on the right side of the screen (Figure 6.4.1.4-C). The pressure reading turns gray during this time to indicate an invalid value. Table 6.4.1.4 displays different scenarios requiring Zero and Span calibration. Span button Figure 6.4.1.4-A Span Button Figure 6.4.1.4-B Span Calibration Required Figure 6.4.1.4-C Span Calibration Process WARNING!

PN 0019408001A 12/2018 EN EN 7.6 Mensor Command Set This Mensor command set is the default on the CPD8500. For queries (ending with a ?), the Data column represents the response of the CPD8500. All response strings begin with a space character or an “E” representing that there is an error in the error queue. All response strings are terminated with a and a . The error queue holds the last 10 errors identified. For all commands (no ?), the data column represents the required parameters to be sent to the CPD8500 following the string in the command column. For any command that requires multiple parameters to be sent, the parameters must be separated by commas. 7.6.1 Command and Query Format Commands must be sent in ASCII format and terminated with either a carriage return (), linefeed (), or both. Commands are not case sensitive. Each query returns a response. If an error is detected the response will include an error flag. Command or Query field: Unless otherwise specified, commands are typically converted to queries by appending a question mark to the command. Table 7.10 lists all of the CPD8500 command or query keywords. Data field: The data field is either in ASCII {string} or numeric {value} form. In the case of multiple data fields, commas are required to separate the fields. Queries do not have a data field. String (text) or value (numeric) data are acceptable in any of the following formats: Examples of {string} data: ON, OFF, mBar, inHg Examples of {value} data: 1, 1.0, -5.678, 25.68324e-5 7.6.2 Command Set Definitions In this manual a data entry made up of alpha characters is defined as a string, as opposed to data containing only numbers, such as “Enter 1 for ON or 0 for OFF” where 1 and 0 are defined as values. Command: Any command or query listed in Table 7.6.4. For commands that take boolean data the following strings are acceptable: 0 1 False True No Yes Off On Separator: Space (SP). Data: ASCII representations of numbers, {value}, or alpha characters, {string}, data as defined above. When sending code a literal variable replaces the brackets and the enclosed character(s) shown in the following examples. Termination: Linefeed (LF) or carriage return (CR) is used to signal the end of a command statement. For IEEE-488.2 operation “EOI” is an acceptable alternative. Always send commands in one of the following formats: 1. [Command] [Termination]; 2. [Command] [Separator] [Data] [Termination]; 3. Queries are special instructions in the form: [Command?] [Termination] where the question mark, “?”, immediately precedes the terminator. When a valid query is received, the CPD8500 will return {data} terminated by CR and LF. Floating point data is returned in the current engineering units in exponential format. 7.6.3 Output Formats Pressure readings are returned in exponential notation in a format according to the OUTFORM command as follows.

If you have questions not covered by this manual, call 1-800-984-4200 (USA only), or 1-512-396-4200 for assistance, or send an email to [email protected]. 8.1.1 Beyond the Warranty Take advantage of Mensor’s expert product care. Mensor provides complete maintenance and calibration services, available for a nominal fee. Our service staff is knowledgeable in the innermost details of all of our instruments. We maintain units that are in operation in many different industries and in a variety of applications, and by users with a wide range of requirements. Many of these instruments have been in service for over twenty years, and continue to produce excellent results. Returning your instrument to Mensor for service benefits you in several ways: • Our extensive knowledge of the instrument assures you that it will receive expert care. • In many cases we can economically upgrade an older instrument to the latest improvements. • Servicing our own instruments which are used in “real world” applications keeps us informed as to the most frequent services required. We use this knowledge in our continuing effort to design better and more robust instruments. • Repair or replacement of the CPD8500 chassis, module and measurement transducers will be available up to 7 years after the production life cycle of the product, pending external vendor parts or equivalent parts availability. The production life cycle is defined as the time from the product series launch to the announcement of discontinuation (typically 8 to 10 years). • All repairs associated with the chassis or internal modules should be performed by Mensor due to the complexity of performing these repairs. Replacement of measurement transducers can be done at the customer’s site. 8.2 Recalibration 8.2.1 Calibration Services by Mensor or WIKA worldwide Mensor and WIKA worldwide have extensive experience and knowledge of Mensor products. Calibration of the transducers in these products can be performed at the addresses below or by competent internal or external labs using the procedures in this section.

In addition, the instrument should be at rest on a stable platform that is free of excessive vibration and shock. 8.2.3 Pressure Standards Mensor recommends the use of appropriately accurate primary pressure standards when calibrating this instrument. Such standards should be sufficient so that when the techniques of the ISO Guide to the Expression of Uncertainty in Measurement (GUM) are applied, the instrument meets its accuracy statements as required by ISO/IEC 17025:2005, or other applicable standards. 8. Maintenance and Recalibration

PN 0019408001A 12/2018 EN EN 8.2.4 Media The recommended calibration medium is dry nitrogen or clean dry instrument air for the absolute CPD8500. For the gauge CPD8500, it is recommended to calibrate the measuring head in clean dry air and lubricating the measuring head with recommended lubricating oil mentioned in Section 5.3.2. A height variation between the standard and the CPD8500 can cause errors. A calculation should be made to compensate for this difference. This compensation can be done in Section 8.2.8 Reference Level. WARNING! Before proceeding with calibration on any components inside the CPD8500, it is essential to set the Local Gravity. This is a critical parameter for accurate calibration results. Refer to section 8.2.9 Reference Level for detailed instructions. 8.2.5 Calibration Data The Calibration Data Application is where the calibration data for each component (measurement head, temperature probe, EMM components, optional internal barometer and optional internal vacuum sensor) of the instrument is stored and amended. Each calibration data consists of the serial number (S/N) and Pressure Type (if relevant) can be seen in this screen. The date of calibration can be entered by pressing the corresponding button and entering the date with the keypad. Pressing the Check [ ] button confirms the date entry. The certificate name and number can be entered by pressing the corresponding button. This opens a alpha numeric keypad. To save the name of the certificate press [ ].

Pressing OK [ ] in this screen will save the calibration to the memory of the device. 8.2.6.3 Linearization The linearization calibration sequence provides a place to record upscale and downscale calibration data and to linearize each device using that data. An “As Found” or “Live” calibration can be performed in either the upscale or upscale and downscale direction using anywhere from three to eleven points across the complete range (Figure 8.2.6.3-A). The record of the readings from the reference standard and the corresponding reading from the instrument’s device/component can be recorded and transcribed into the linearization Matrix. The menu also allows the user to plot the linearization matrix into a graph for a visual display of the linearity curve of the device. Furthermore, the curve can also be displayed in terms of its segment, slope and intercept information. The Linearization menu pages can be navigated by Next [ ] and Back [ ] buttons to access main settings, linearization table, graph and curve. Linearization calibration sequence is only available for measuring head, head temperature probe, internal barometer and internal vacuum transducer. Figure 8.2.6.3-A Linearization Settings Page one of the linearization sequence provides a place for user to enter the settings for the linearization including type of calibration (As Found/Live), calibration cycles (Upscale/Downscale), number of points (3-11) and units of calibration. The “Pressure Type” button can be toggled between Gauge and Absolute if a pressure device is being linearized. The “Restore Factory Linearity” button overwrites the factory linearity for the active device. Page two of the linearization sequence is the Linearization Matrix. The menu automatically populates the screen with equidistant increments from low to high values corresponding to the range of the active device. Each value from the reference standard can be entered under the “Reference” column, corresponding upscale and downscale readings from the device can be entered under the respective “Reading” columns. In “As Found” mode, simply enter the reference & reading values by pressing the number and a keypad will appear where the number can be entered. Press the check mark [ ] to accept each value. Figure 8.2.6.3-B shows typical linearity values for the head temperature probe.

Maintenance and Recalibration 8.2.9 Reference Level The Reference Level Application provides an automated way to calculate the reference level offset between a device being tested and the CPD8500, based on ■ Media (gas) type ■ Height: the difference between the device under test and the transducers in the CPD8500 (Difference = DUT - CPD8500) As an example, if the device under test (DUT) is 10 inches above the CPD8500, enter +10 in “Height” button with the “Imperial” units ■ Gas Temperature ■ Local Gravity ■ Gas Density: the density of the pressure media The Reference Level application is placed under the password protected area of the operator interface to safeguard against inadvertent activation. It is intended to be used to accurately measure the pressure at an external source that is at a different elevation from the CPD8500 sensing that pressure. The Reference Level App allows for presets to be saved for pressure medias; nitrogen and dry air with input methods in both imperial and metric units. To enable a preset, simply press the “Nitrogen” or “Dry Air” button. To create custom parameters, simply enter the individual values in the “Custom” button. These four parameters are used to calculate the pressure that is a result of the different elevations. It should not be used when calibrating CPD8500. The Reference Level should be set at zero before calibrating the CPD8500. The reference level should not be active when calibrating CPD8500. The reference level should be set at zero before calibrating the CPD8500. Difference in height between the laboratory standard and the CPD8500 during calibration should be factored into the uncertainty analysis. Figure 8.2.9 shows the Reference Level screen. The height, gas temperature, local gravity and gas density can be entered here based on the specific setup of the system. Figure 8.2.9 Reference Level App (Nitrogen)

Accessories ■ Barometric reference sensor (for pressure emulation) ■ Vacuum transducer ■ Absolute accessory kit ■ Vacuum pump requirements ■ Gauge accessory kit ■ Upgrade accessory kit ■ External mass set ■ EMM calibration sled ■ Barometric reference calibration sled 11.1 Barometric Reference Sensor The CPD8500 can be ordered with an internal barometric reference sensor. It is a very stable, absolute pressure transducer, used to accurately measure local atmospheric pressure. It is used to display the barometric pressure (reading appears on the bottom right side of the display) or as a barometric reference for absolute emulation. The barometric reference sensor is installed inside the CPD8500 base. 11.1.1 Absolute Pressure Emulation In the Home Application (main screen) a gauge instrument will indicate “Gauge” in the Pressure Type button (this is the default mode). When the Pressure Type button is pressed the button label will toggle to “Absolute” and the color of the button turns yellow. This change in color is an indication that the instrument is in emulation mode. In the absolute emulation mode the atmospheric pressure reading from the barometric reference transducer is added to the gauge pressure reading of the instrument to emulate an absolute pressure. The instrument is only able to emulate absolute pressures above atmospheric pressure. Sub-atmospheric measurement is not possible. 11.1.2 Emulation Mode Accuracy The accuracy in emulation mode is different for absolute and gauge emulation mode. The barometric reference has six significant digits and has a guaranteed drift of 0.0000041 psi over a 24 hour period. The absolute uncertainty of the barometric reference must be considered in the emulated absolute pressure uncertainty. 11.1.3 Barometric Reference Calibration The Barometric Reference Transducer can be calibrated in exactly the same manner as the other installed components as described in Section 8.2 Recalibration. Alternatively the barometric reference can be calibrated outside of the instrument using a calibration sled or adapter (section 11.9). 11.2 Vacuum Transducer The vacuum transducer is installed inside the absolute CPD8500 base. The vacuum transducer is used inside the instrument to measure residual pressure inside the reference chamber, when performing absolute mode measurements. The vacuum transducer is a highly stable vacuum transducer which enables performing a Zero calibration on the absolute CPD8500. Figure 11.2 shows the vacuum transducer outside the instrument. Figure 11.2 Vacuum Transducer 11. Accessories

PN 0019408001A 12/2018 EN EN 11.3 Absolute Accessory Kit The CPD8500 Absolute base accepts two styles of absolute heads: low pressure (1-5 bar) and high pressure (10-20 bar). The low pressure heads feature three KF-16 flanges which are used to connect to vacuum, vent, and working pressure, and the high pressure heads feature a DH1500 port. The accessories included with a CPD8500 Absolute base contain the necessary components to adapting any of these heads (Figure 11.3). This accessory kit includes the following components: ■ Pressure fittings ⇒ KF-16 to DH1500 Port Adapter ⇒ DH1500 Port to 7/16-20 Female Adapter ■ Vacuum components ⇒ 3x Sintered Filter KF-16 Centering Rings ⇒ 7x Standard KF-16 Centering Rings ⇒ 3x KF-16 Plug Discs ⇒ 10x KF-16 Clamps ⇒ 3x Vacuum Valves ⇒ 0.5m KF-16 Flexible Hose ⇒ 1.0m KF-16 Flexible Hose ⇒ KF-16 Elbow ⇒ KF-16 Tee ■ Vacuum metering kit ⇒ KF-16/NPT Tee ⇒ 1/4” NPT Male to Female Fitting ⇒ Metering Valve ⇒ 1/4” NPT to 1/8” NPT Female Reducer Fitting ⇒ Breather Vent Filter ■ Vent filter kit ⇒ Coalescing Filter ⇒ KF-16 to 1/8" NPT Male adapter ⇒ Breather Vent Filter ■ Tools ⇒ 12mm Wrench ⇒ 15 mm Wrench ⇒ 5mm T-handle Hex Driver ■ Miscellaneous ⇒ Loaded USB Drive ⇒ Inspection Gloves ⇒ Silicone Tubing for Calibration of Environmental Measuring Module Pressure fittings are included to adapt an absolute head to a customer’s system as needed. Vacuum Components are common to both measuring heads. KF-16 centering rings with sintered filters are recommended for use near the head connections to prevent contamination of the piston-cylinder assembly. The Vacuum Metering Kit is included to allow fine control of vacuum pressure. A reference pressure of less than 2 Pa can often result in device malfunction. The Vent Filter Kit is included to vent the head pressure to atmospheric pressure through a fine coalescing filter to prevent contamination. . The 12mm Wrench is for use with DH1500 male fittings (not provided), the 15 mm Wrench is for use with the DH1500 port to 7/16-20 female adapter and the 5mm hex driver is for installing and removing measuring heads and the protective cover which prevents contamination when no head is installed. 11.

PN 0019408001A 12/2018 EN EN 11.8 EMM Calibration Sled The Environmental Monitoring Module (EMM) can be calibrated both inside and outside the instrument. For detailed instructions on calibrating the EMM inside CPD8500, follow instructions in Section 8.2.6. To calibrate the EMM outside the CPD8500, a calibration sled or adapter is required for the EMM to communicate with a computer. The primary function of the calibration sled is to allow communication of the sled via RS-232 port. The calibration can be done by reading the EMM remotely by the PC and comparing the values of each sub component with the reference standard. The calibration sled also requires a 12 V DC power source. Figure 11.6 EMM Calibration Sled The calibration sled software along with detailed instructions on setup and calibration can be found on the Mensor website. 11.9 Barometric Reference Calibration Sled The Barometric Reference Calibration Sled Kit is available to provide a way to calibrate the barometric reference remotely. Calibration of the Barometric Reference can be performed remotely using the Cal sled, a PC and the software provided. Figure 11.9 Barometric Reference Calibration Sled 11. Accessories
