1. INTRODUCTION
The Multifunction Instrument is a panel mounted 96 x 96mm DIN Quadratic Digital Panel Meter, which measures
important electrical parameters in 3 ph 4 wire / 3 wire / 1ph Network and replaces the multiple analog panel meters.
It measures electrical parameters like AC voltage, Current, Frequency, Power, Energy (Active / Reactive /
Apparent), phase angle, power factor, individual harmonics & many more. The instrument integrates accurate
measurement technology (All Voltages & current measurements are True RMS upto 31st Harmonic) with LCD
display with backlit.
It can be configured & Programmed at site for the following : PT Primary, PT Secondary, CT Primary, CT
Secondary 3 Phase 3W, 3 Phase 4W, 1 Phase 2W system.
The front panel has four push buttons using which the user can scroll through different screens & configure the
