ETCR4320 Large Caliber Three-phase Digital Phase Voltmeter
Notice:
The standard package don't include batteries.Because,the international air shipping forbid to ship liquid,powder and batteries,we can not put them in the package box.Hope you can understand buy them in your local store or supermarket.
At the same time, please forgive us that we are unable to provide the English user manual. If you need it, please contact the customer service after purchase.
Thanks for your support!

Function
|
in the case of the tested circuit is not open-loop, measure two AC voltages, current, phase between voltages, phase between currents, phase, frequency, phase sequence, active power, reactive power, apparent power, and power factor between voltage and current. Discriminate the transformer wiring group, inductive and capacitive circuits, test the secondary circuit and the busbar protection system, read the phase relationship between the CTs of the differential protection groups, check the wiring of the meter for correctness, and repair the line equipment, etc.
