Product Description


Class 0.02% /0.05% for active and reactive energies, over the entire load range & independent of the measuring mode.

There are three ports for pulses to output. And its constants can be set automatically or manually. Types of constants can be set also: active power, reactive power, apparent power, voltage, and current.

Adjustment of electric energy error: it can adjust the estimate value of standard deviation and computation error of electric energy meters as well as calibration device for energy meter. Moreover, counts of pulse and constants of meters to be checked can be set automatically so as to work effectively. Especially for the multi-constant standard meter and the energy meter calibration device, it will be more convenient. By adopting the use of special compensation techniques, error-beating would not be large because of the small load (the low frequency of the energy pulses). It can display the current error, the value of the standard deviation estimate and the average error.

Multiple ports for communication: RS485, RS232, USB, and baud rate can be set when using asynchronous communication.

The measuring range can be switched manually or automatically.


Key Function:

It has ability to measure AC voltage, current, power (active power, reactive power, apparent power) and electric energy in four-quadrant with connection modes such as 1P2W and 3P4W (Y) / 3P3W (Δ). In addition, it can measure reactive power and electric energy with ways of true reactive, cross-phase reactive power, artificial neutral point of reactive.
