DC 100V 100A Voltmeter Ammeter Volt Amp Meter Voltage Current Tester with Shunt

Description

DC 100V 100A Voltmeter Ammeter Volt Amp Meter Voltage Current Tester with Shunt

Simultaneously monitor DC voltage up to 100V and current up to 100A • A heavy duty 75mΩ external shunt handles the current
Auto ranging 0.01V 0.01A precision • ±0.1% voltage tolerance • ±1% current tolerance • Working current: Size: 48x29x22mm • Hole size: 46x27mm • Operating Temp: -10℃ – 65℃ • DC only, not for use with AC • 4-28V supply voltage
There are potentiometers on the back of the unit to calibrate voltage and current. In order to get accurate readings, it is necessary to calibrate against a known voltage and current on first use. The meter may display 0 current until it has been calibrated.
Note: If the meter supply voltage (thin red wire) is the same as the load, then it must only be used with 4-28V or the meter may be damaged
