Features:
- If the current shows 0, please check the wiring carefully.
- Inaccurate current display: If the direct or independent power supply shares the same ground with the equipment power supply, just disconnect the thin black wire.
- All AC rectified electricity must be connected to an electrolytic capacitor above 1000uF for filtering before supplying power to the meter.
- When discharging: Battery, switching power supply and transformer are power supply, and resistance, electric lamp, motor and electric equipment are loads.
- When charging: Charger, generator and solar energy are the power supply, while charging pool and battery are the load.
Specification:
Working Voltage of Meter Itself: DC 4V - 30V
Working Current of Meter Itself: Less Than or Equal to 20mA
Voltage Measuring Range: DC 0V - 100V
Current Measuring Range: DC 0A - 10A
Voltage Resolution (V): 0.1V
Current Resolution (A): 0.01A
Measure Accuracy: 1 Percent (-1 Percent to 1 Percent)
Display: 0.28 Inch Digital Tube(Two Color Blue and Red)
Refresh Rate: About 300mS / Times

Note:
- The maximum input voltage can not exceed 30V. Otherwise the meter will be burned.
- The wiring for discharging is different from that for charging.
- The current can only be measured in series at the negative pole of the power supply and the negative pole of the load.
- Make sure that the thick black wire is connected to the negative of the battery and the thick red wire is connected to the negative of the load.
