Portable Meter Testers

Specially designed instruments for testing of meter installations on site


Portable Reference Meters

ZERA offers a series of reference meters which can meet a variety of requirements. Primarily they are used for testing of meter installations and for observing error limits of electricity meters on site.

Accuracy class 0.2:       MT10       MT30

Accuracy class 0.1:       MT310     MT360

Accuracy class 0.05:     MT320     MT365

Accuracy class 0.02:     MT3000


Portable Test Systems

ZERA's portable test systems comprise of a reference meter with an integrated source. These are particularly useful for testing meter installations with defined currents or currents and voltages in one single device.

Products:

MT681     Accuracy class 0.1, 100 A current source

MT686     Accuracy class 0.05, 100 A current source

MT680s   Accuracy class 0.1, 120 A current source

MT781     Accuracy class 0.1, 120 A / 500 V current and voltage source

MT786     Accuracy class 0.05, 120 A / 500 V current and voltage source


Sources

While testing meter installations on site, often a sufficient load is missing to achieve reliable results. Sources are available to generate currents up to 120 A and voltages up to 500 V.

MT400     Current source up to 12 A

MT500     Current source up to 12 A and voltage source up to 300 V

MT551     Current source up to 120 A and voltage source up to 500 V
