Working environment.
Operating Temperature: -10-50℃
Working humidity: 10-80% (no condensation)
Working Pressure: 80-106kPa
Sun exposure: not directly exposed to the sun.
Please note:
1.10A or less than 10A: All direct measurements, built in sampling resistor, no external shunt or sampling resistor required.
2. More than 10A: Shunt is not included. To work, a 75mV shunt must be connected even if it is 0.1A. Otherwise it will be burned.
3. If there is a shunt, please refer to the shunt technical data specification (75 mV is the company standard)
4. The meter has a common ground, i.e. the test end of the IN and the power side of the negative pole are connected, so the ammeter can only be connected between the load and the negative pole of the power supply and is recommended for the recommended use of an independent power supply
5. If you choose the power supply DC5V, the working voltage is 5V±0.5V, otherwise it will be burned.

Use:
Red cable: positive pole.Black cable: negative pole.
