Function:
Real- time  Measurement and indication  on AC or DC Voltage(Current) in  an electric circuit; Programmable  CT/PT ratio; Higher and lower limit alarm output and programmable rely time of alarm.

Measuring range:

AC ammeter AC 0.05-6A, external CT is necessary if more than 6A.
DC ammeter DC 0.05-6A, external electrical shunt is necessary if more than 6A.
Accuracy: ±(0.5%FS + 1 digit)
Measuring display mode:4 LED nixietube effective value display.
Resolution: last figure one digit
Overflow indication the top digit display “1” or "-1" and other digit hiding
Auxiliary power supply: AC 220V±10%
Alarm contact capacity: AC 250V/1A
Alarm Shift Difference :0.1 %FS -50.0% FS
Alarm  Delay time: 0.0-99.9s Programmable

Terminal arrangement and wiring connection:

Power : Auxiliary power input port of instrument, Auxiliary power suppy is AC 220V±10%(please note if you need special power supply) .
Input: Signal input port of instrument, HI represents "+“  port of DC input signal. fire wire terminal of AC voltage input  signal and inlet wire terminal  of AC current input signal.
LO : "-" port of DC input signal, the other one wire of AC voltage input signal;the outlet wire terminal of AC current  signal input
OUT: the alarm contact output port of meter
