Description
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)
