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
