General Specification
Function
Simultaneous measurement of two AC voltage, current, phase
between voltage, phase between current, phase between
voltage and current, frequency, phase sequence, active power,
reactive power, apparent power, power factor, distinguish
transformer wiring group, inductive and capacitive circuits, test
second circuit and bus differential protection systems, read the
phase relationship between CTs of the differential protection,
check the meter wiring right, repair lines and equipment, etc.
