Specifications:
 

Digital Ammeter Voltmeter Current Electric Energy Meter AC200V-450V 

Description:
The item is a multi-function meter. On the instrument, it can respectively display the measured AC voltage, AC current, active power, apparent power and power factor at the same time. 

Feature:

Wide voltage and current measurement range 
Display the AC voltage and current, etc. simultaneously by LED digital tube 
Measure AC voltage, AC current, active power, electric energy and power factor 
Suitable for monitoring the operating situation of appliances 
Operation:   
Connect the wires (blue wire) of secondary transformer to the blue terminal on the meter, the meaure line must across the hole in the current transformer; 
Connect the measure voltage wire to the green terminal; 
The default disply power is active power(V), click the suwitch (SAMCK) can, change to the reactive power (VA) and power factor(cosX)

Display Mode:  
AC voltage and power factor 
Four red 0.32-inch LED digital tube; 
Current 
Four red 0.32-inch LED digital tube; 
Active power, electric energy  
Five 0.32-inch LED digital tube; 
Measuring Range: 
AC voltage:  
AC200.0-450.0V; 
Current 
AC 0.0-100.0A(the resolution radio will change by itself, when input current lower than 10A, the resolution ratio is 0.01A; when input current higher than 10A the resolution ratio is 0.1A); 
Active power: 0.0-45000W 
Reactive power: 0.0-45000VA 
Power factor: 1.000-0.0001.000-0.000 

Attention: 
Voltage connect to the blue terminal and secondary transformer connect to the blue terminal, wrong connection will destroy the meter. 
The only uses for 50Hz-Electric supply. Do not support for square wave, Inverter output and other input, all of these will destroy the meter.
