Meter Testing

In order to test meters, particularly those of the 0.2s class, a testing device with a high degree of accuracy is required. The concept of individual on-site meter testing with current and voltage sources has become increasingly popular. Our test technology for meter testing is particularly versatile and suitable for on-site testing and for use as a laboratory test system.

The flexible combination of CMC test set, operating software and accessories always offers an ideal solution for testing electrical meters.

CMC test set

All CMC test sets can be used for testing energy meters. The CMC models differ in their accuracy, which means that not every meter can be tested with every CMC. The selection below will help you choose the CMC that suits your needs.

For testing energy meters up to class 1s
CMC 500
CMC 310 (Operating only with CMControl P)

For testing energy meters up to class 0.2s (most accurate)
CMC 430

Operating software

Quick and easy meter testing

CMControl P is a cost-effective CMC operating option which is particularly suitable for quick and easy meter tests.
CMControl P

Advanced and automated meter testing

Test Universe is the first choice CMC operating option for parameter related testing of protection and measurement devices. It is ideal for performing automated meter tests with advanced functionality (e.g. with harmonics).

The minimum requirements for meter testing with Test Universe are:

Test Universe “Essential Package” plus the module “Meter”

Test Universe (main software)
Meter module (software module)

Accessories (for automated testing)

Optical scanning heads enable Closed-Loop testing to be performed on energy meters. Different optical scanning heads are available for counting the optical LED pulses from electronic or rotor marks of electromechanical meters.

Scanning heads that connect to the external interface (EXIF) connector of the CMC 430 or CMC 310 test sets: SEM 1, SEM 2, SEM 3

Scanning heads that connect to a test set’s binary input: Optical scanning heads for meter testing
