Simultaneously monitor DC voltage up to 100V and current up to 100A A heavy duty 75m external shunt handles the current
Auto ranging 0.01V 0.01A precision ± 0.1 % voltage tolerance ±1% current tolerance
Working current: <20mA Refresh rate: 300ms
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
