Taidacent Ohm Meter Resistance Tester Ohmmeter Digital DC Resistance Measuring Instrument Fixture Resistance Measure Panel Meter (200K Ohm, DC5V with Cover)

• 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).

Fluke BT510 Battery Analyzer

• [ Polarity Testing & Continuity Testing ]: The power circuit probe tester can be used to test uncertain contact polarity in vehicles. When the it touches the positive pole, the indicator light will turn on red, and when it touches the negative pole, it will turn on green. In addition to polarity testing, the power short circuit finder can also perform continuity testing, it is mainly to test whether the circuit has continuity and whether it is short-circuited..
• [ Quickly Tracking and Locating ]: The circuit tester is mainly used to test the on-off condition of the automobile electrical system under the 6-24V DC voltage. In most cases, a short circuit or momentary overload of a component will cause a fuse or circuit breaker to blow. When the fuse is blown due to a short circuit, using this circuit tester can help you quickly and accurately find the faulty wire and its fault point..
