2. Functionality

: accurately measures phase voltages, line voltages, line currents,

1. Multi-function

active, reactive and apparent power, phase and total power factors, frequency and

maximum demand.

2. Harmonics

: the IC995 measures component harmonics up to the 31st inst and THD

for both current and voltage.

3. Network analysis

: displays 4-quadrant energies, including active capacitive energy,

active inductive energy, reactive capacitive energy and reactive inductive energy. Also

measures current "K" factor, voltage crest factor, waveform factor and degree of voltage

and current imbalance.

: the IC995 is provided with 4 digital inputs, 2 digital relay outputs,

4. Inputs/Outputs

1 volt-free pulse output (set at 10kWh/pulse) and 1 RS485 (Modbus protocol) output

in order to satisfy remote meter reading and system control monitoring.
