Minimum resolution(V): 0.1V
Measure current:50A (require external shunt)
Minimum resolution(A): 0.1A
Operating current: <20mA
Display: three 0.28" LED digital tube
Display color: red and blue (two-color display)

Mounting cutout: 45.5 x 26.5mm
Refresh rate: about 500mS / times
Measure accuracy: 1% (+/- 1 digit)
Operating temperature: -10 to 65 Celsius
Operating humidity: 10 to 80% (non-condensing)
Working pressure: 80 to 106 kPa

Wiring:
Black line (thin): vacant or buck circuit (module) negative
Red line (thin): positive pole of power supply
Black line (thick): COM, common measuring terminal
Red line (thick): PW+, input terminal of measuring positive voltage
Yellow line (thick): IN+, the positive of current input
(Please refer to the wiring diagrams for more details)

Notice:
The voltage between the thin red and thin black lines must be within DC 4.5-30V
The ammeter can only be connected to the negative of the device under test and can only test amp in positive direction
Exceeds 5A, long-term full load working continuously, we recommended test side of leads directly soldered to the socket
When black thin line vacant, it is better to use insulating tape around exposed part of wire to prevent short circuits
If just used voltmeter, we recommended yellow line and black line connected together to prevent ammeter's digit flashing

Package includes:
1x Digital Volt/Ampere Meter
1x 50A/75mV Current Shunt
