Single phase AC / DC Ammeter or Voltmeter or Frequency Meter Operating Manual
I、Main Technical Data
1.1 4 analog digital display,Display Range:0.000-9999;
1.2 Accuracy Class:Class 0.5、0.2;
1.3 Overload:Continuous:1.2times,Instantaneous:current 10 times/5seconds,voltage 2 times/1 second。
1.4 Nominal input:AC current 1A、5A;AC voltage 100V、220V、380V、1000V;
DC current 75mV、20mA、4-20mA; DC voltage 2V、20V、200V、1000V。
1.5 Power Supply: AC220V; AC/DC 85~265V;AC380V;DC 48V;DC24V;DC12V
1.6 Power Consumption:≤2VA;
1.7 Dielectric strength:2kV/1min;
II、Wiring Diagram:Refer to real object.
III、Setting explain
1.1)Keyboard button:
“SET ”: Menu Editor or the value of bit shifted to the right (in the digital input mode); “ ”:Menu items on the move or incremental value;“ ” :Menu item down or diminishing value; “ ” :Used for menu moving backward, the parameter is set back off and save your settings。
Note:1、“SET ” :the value of bit shifted to the right, in the password input mode or CT、PT value input mode。
2、AC current CT value:CT=Current transformer primary current value / Current transformer secondary current value
DC current CT value:
CT=Shut primary current value/5(signal input DC 75mV)
CT=display value/1(signal input DC 20mA、DC 4-20mA)
3、AC voltage PT value:PT=Voltage transformer primary voltage value/ Voltage transformer secondary voltage value
4、DC voltage PT value:PT=display value/input value
2)Indicator light:
“k”:thousand,K means that the practical value is display is 1000 times。

IV、 Attention Before using
1. Working temperature: -25~+55℃;
2. Wiring of terminals shall be checked correctly and firmly before electrified;
3. No calibration if no standard machine or professional staff;
4. The current in the circuit terminals must be tightened through the screwdriver to ensure reliable lead contact and avoid producing an accident;
5.When the nominal current is over AC 5A, one more current transformer is needed.(Secondary current 5A)
