The M842 is a compact, 3 phase power meter.

The M842 measures Volts, Amps, Frequency, Active Power, Apparent Power, Reactive Power, Active Energy, Reactive Energy, Power Factor, Amp Demand, Apparent Power Demand, Active Power Demand, Maximum Amp Demand, Maximum Apparent Power Demand, Maximum Active Power Demand, and THD on voltages and currents.

Voltage and current measurements are true RMS.

Product code:
M842-SB1 Single Phase
M842-SB1-3 Single Phase 3 wire load
M842-SB4 3 Phase 3 wire unbalanced load
M842-SB9 3 Phase 4 wire unbalanced load

The MultiDigit is designed to be user friendly and simple to use. All operations, including programming, are performed by using the two push buttons on the front of the instrument.
MultiDigit units are pre-programmed by the factory and no further programming is necessary. However, a user can reprogram most parameters in a MultiDigit e.g. nominal current and voltage inputs, relay output etc. The reprogramming operations are covered in the manual (see section 4).
