DROK 0.28 Inches DC 0-100V 10A Digital Voltmeter Ammeter

DROK 0.28 Inches DC 0-100V 10A Digital Voltmeter Ammeter Voltage Current Tester Gauge Red Green Bright LED Display Five Wires Volt Amp Meter for Solar Battery Monitor Car Motor Panel Mount
- Voltmeter Range: DC 0-100V (resolution of 0.1V); Ammeter Range: DC 0-9.99A.
- Display: Dual 0.28" three digit Red/Green LED tube, very bright and clear.
- Compact design and well made, the dimension is 48mmx29mmx21mm, cutting size 45mmx26mm.
- With built-in shunt, you can wire it directly in to get current rating and don't need an isolated power supply.
- Has zero calibration button "KEY" and current calibration potentiometer "R7" on its back to do finer adjustments.

Ammeter Range: DC 0-9.99A (Direct measurement, no requirement of shunt)
Display: Dual 0.28" three digit LED tube
Display Color: Voltmeter Red, Ammeter Green
Refresh rate: about 500ms / times
Accuracy: + / - 1% + 2 digits

Wire Connection:
Thin Red line (VCC): Power Supply + (DC 3.5-30V +)
(if the measure voltage between DC 3.5-30V, then the Thin Yellow line and Thin Red line can connect together)
Thin Black line (GND): Power Supply - (DC 3.5-30V -), Measure Voltage - (DC 0-100V -)
Thin Yellow line (VIN): Measure Voltage + (DC 0-100V +)
Thick Red line (I+): Current Input +
Thick Black line (I-): Current Input -
More detail please check the description picture.

Error Phenomena:
Due to the aging of the device and change of ambient temperature
1. the error becomes larger when measuring small current
Solution: When there is no load, short-circuit 2 pads of KEY and then power on, the module will automatically do zero calibration, after that shut off the module and cut the short circuit point.
2. the error becomes larger in whole measurement range
Solution: When connecting load(half of the range is best), keep adjusting R7 until it displays the same value with the more advanced calibration source.

Note:
If measure the current over than 5A for long time. please welding the wires to the meter port, to avoid High impedance and unstable working.
When the power supply is greater than 24V, please connect a 1k resistor in series to increase the reliability of the product
