True RMS measurement The instrument measures distorted waveform up to 15 Harmonic. uto re-closure / Manual reset In auto re-closure mode instrument automatically tries to re-connect load within a programmable specified time. If the fault persists it disconnects the load. If device set into manual mode, then device must be reset manually by push button. th djustable set point & set delay for -eakage Current -Pre alarm -ver Voltage -Under Voltage -ver Current -Under Current -Reverse Power Previous fault storage Instrument memorizes the last 15 faults occurred. Trip relay cum PM indication - indication for relay-1, relay-2 status. - indication for one model, 1, 2 for two model and V (Voltage), I (Current) and k for R VI Model. - Trip indication are displayed on 4 igit display. 4 digits ultra bright display User selectable password protection Test and reset key on front Panel display.
