0-100V 20A Double Display Volt Meterr Current Meter Digital LED

Description: 
0~100V 20A Double Display Voltmeter Current Meter Digital LED. 

Features: 
The double table small size, can simultaneously, with the screen display voltage, current. 
A total of design, which is a measure of the ends of the earth wire and the power supply end of the ground is interlinked, so the header only on the "negative" test current. 
Equipped with voltage calibration potentiometer, current calibration potentiometer, such as error, can be their own calibration.
Automatic design of decimal point. 
Use of "all the shell" design, with the back cover, safe and reliable, dust. 
Anti disturbance ability, display refresh rate. 
Convenient wiring, wide use, can be used to monitor the battery, DC can adjust the power, or other equipment, voltage, current changes state. 
With exquisite SMT process, so the consistency is very good.
