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。

3) Display character explanation：

Character	Instruction	Parameter and specification
SET	Setting	0000-9999
CT	Current ratio	0001-9999
PT	Voltage ratio	0001-9999

 

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)
