- Optional power supply: DC5V or DC12V, with a current consumption of less than 50mA
- Common ground instrument; non-isolated design recommends using a separate power supply that is independent of the signal source
- Cannot measure resistance with power applied; doing so may damage the meter
- Choose the appropriate measurement range; too high a range may prevent detection of small resistances or result in inaccurate readings
- The meter uses a common ground configuration; for safety, use an isolated power supply that is independent from the measurement terminals

- Power supply: DC5V/DC12V optional (current consumption is less than 50mA)
- This ohmmeter is a common ground instrument, non-isolated, it is recommended to use a separate power supply, that is, the power supply is not related to the signal
- The resistance meter cannot be measured with electricity, otherwise the meter will be burnt out
- Select a suitable range, if the range is selected too much, the small resistance cannot be recognized or the measurement is inaccurate
- The meter head is a common ground instrument (that is, the negative pole of the power supply and the negative pole of the signal are connected), it is recommended to use a separate, independent, and isolated power supply (that is, the power supply and the measurement terminal are not related)
