Features

1) Can be controlled by computer through RS232 setting the parameters and then test by control software;

2) Can be used independently also can be used together with reference standard meter.

3) With LED indicator on the face plate after power on the unit

4) With voltage measurement facility and loop back control

5) With measurement mode selection, namely 3P3W, 3P4W and 1P2W. When select 3P3W, automatically

    deactivate L2 phase current and when select 1P2W, automatically deselect L2 and L3 phases.
