Product Review
parameters:
Operating voltage: DC 4.5 ~ 30V
Measure the voltage: DC 0 ~ 100V
Minimum resolution (V): 0.1V(when >10V)
Minimum resolution (V):0.01V(when <10V)
Measure current: 2A / 5A / 10A / 50A / 100A (> 10A, need external shunt)
Minimum resolution (A): 0.01 A
Operating Current: <20mA
Display: three 0.28 "LED digital tube
Display Color: Red + Red; Red + Blue (Dual Display)
Dimensions: 48 x 29 x 21 mm
Refresh rate: 500 ms / times
Measuring accuracy: 1% (± 1 digit)
Operating temperature: -10 - 65 ℃
Humidity: 10 to 80% (non-condensing)
Working pressure: 80 to 106 kPa
wiring:
Black line (thin): vacant or buck circuit (module) is negative
Red line (thin): Power Supply +
Black line (thick): COM, common measurement
Red line (thick): PW +, measuring terminal voltage input positive
Yellow line (thick): IN + input + current
Please note:
The operating voltage must be DC 4.5-30V.
The ammeter can be connected only to the negative of the device.
≤10A, built-in shunt, no need external shunt; > 10A, need external shunt.
When the black thin line free, it is better to use insulating tape around the exposed portion of the wire to prevent short circuits
If only be used as a voltmeter, connect together the yellow and black line.
Package Included:
1x digital amp volt meter
