4. Description of unit
Power Monitor is used to measure electrical power (voltage, current, etc.), power factor, frequency etc. using
AC voltage and AC current input via one of the following systems: single-phase two-wire system, single-
phase three-wire system, three-phase three-wire system or three-phase four-wire system.
It features a built-in thermistor to measure the temperature of the installation site, e.g. inside the panel board,
for your reference.
Power Monitor is primarily designed to manage energy-saving. It is neither intended nor can it be
legally used for billing.
