Measure voltage range: DC 0 ~ 100V
Minimum resolution(V): 0.1V
Measure current range:100A (require external shunt)
Minimum resolution(A): 0.1A
Operating current: <20mA
Display: three 0.28" LED digital tube
Display colour: Red and Blue (dual colour display)
Dimensions: 48 x 29 x 21mm
Mounting cutout: 45.5 x 26.5mm
Refresh rate: about 500mS / times
Measure accuracy: 1% ( 1 digit)
Operating temperature: -10 c ~ 65c
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): power supply+
Black line (thick): COM, common measuring
Red line (thick): PW+, measuring terminal voltage input positive
Yellow line (thick): IN+, current input+
(Please refer to the wiring diagrams for more details)

Note: If you do not want to connect the Amp meter (eg. measuring the volts of a battery) you can simply connect the thin red (leave the thick red wire unconnected) and yellow wire to the battery + terminal and the 2 black wires to the battery - terminal.
