1 Introduction

This is a guide for the calibration and verification of a CPC 100 unit. It helps the CPC 100 user to verify, whether the unit is still within the tolerance limits as specified in the "Technical Data" section of the "CPC 100 Reference Manual".

To perform calibrations measurement equipment that has a higher accuracy than the unit that is calibrated is needed. Equipment used for factory calibration of all OMICRON units is traceable to national standards (DKD, ÖKD). To ensure an unbroken chain of traceability, all necessary measuring instruments are calibrated and compared to national standards at the DKD (Deutscher Kalibrierdienst) or ÖKD (Österreichischer Kalibrierdienst) laboratories at regular intervals. If a recalibration is done, traceability of the equipment used has to be assured by the user.

The user therefore must take the accuracy of his measuring instruments, his own reference standards and those of the CPC into account. The tables in the appendix can be used to enter the tolerances of the equipment and the results.

If results of the measurements show that the CPC unit is out of the specified tolerance, the unit must be sent to OMICRON electronics for adjustment and recalibration. It is not possible for the user to perform adjustments of a CPC unit. When sending a unit to OMICRON, please attach a copy of the calibration results and send as much background information as possible. Calibration of the CPC is guaranteed for one year after the date of calibration.

The phase calibration will not be elaborated on. The principle of measurement for the common phase measurement devices (i.e. measurement of the zero crossings) is not suitable to measure the phase angle of the CPC (due to high phase resolution as well as widely differing signals; e.g. 2000 V and 800 A). Based on the concept and the digital signal generation of the CPC, it can be assumed that the phase accuracy will also be within the guaranteed specified values if all the other calibration checks prove to be in order.

Warning Only qualified, service trained personnel who are aware of the hazards involved should

remove or connect wiring to the CPC.

Measuring high voltages is always hazardous. All CPC terminals (both front and side) must be considered as hazardous whenever inputs in excess of 42V are connected to any terminal.

Also read the chapter “Safety Instructions” of the CPC100 reference manual.




2 Requirements for Calibration Equipment

The measuring instruments generally need to be of a very high accuracy. Equipment with an accuracy of at least two times better than the guaranteed values of the CPC should be used.

It is adviced to have a valid certificate of calibration for all test equipment listed below before performing any verification with these instruments.

2.1 Recommended equipment or equivalent

2.1.1 Signal generator

Device Type Manufacturer Homepage

Signal generator CMC 256 OMICRON electronics GmbH, Austria

http://www.omicron.at

Any other device can be used as long as the following values can be achieved:

12.5 A AC / DC range, uncertainty < 500 ppm

1.25 A AC / DC range, uncertainty < 500 ppm

400 V AC / DC, uncertainty < 500 ppm

10 V AC / DC, uncertainty < 700 ppm

The full signal quality of the CMC256 is not needed, the tolerances only need to be valid for a short time stability over 5 minutes.

To use the LowLevel-Outputs of the CMC a CMLIB A - Box is mandatory.

4.1 High Voltage Output Magnitude

The voltage is measured at the CPC terminals directly.

4.3 High Current Output 800A AC - Magnitude

To test the current outputs a calibrated shunt of 200 mΩ is required. Please note that the shunt must be designed for AC signals (we recommend bandwidth > 100 kHz). By measuring the voltage drop across the shunt the current can be measured indirectly.

For the 800AAC output and the 1000A/2000A-Booster currents it is suggested to use a high precision current transformer or transducer.

4.5 Burden Outputs

4.5.1 Current Output 6A AC

This output has no internal measurement. Its output magnitude depends on the load and its tolerance is quite big. In typical applications it gains its accuracy from being measured by the according measurement input. However it is possible to check the output by using the CPC internal measurement input, which is by far accurate enough.

Connect the 6A/130V AC output to the I AC/DC input.

Measure the voltage at the CPC terminals directly. Compare the measurement of the measuring instrument against the measurement on the CPC display. The example below shows the circuit for the calibration of the V1AC input. It is suggested to twist the wiring between the digital multi-meter and the device under test. As an example an OMICRON CMC256-6 is used as a high precision signal generator. The voltage output has a voltage range of +/- 300V.
