AUTOOL Car Circuit Probe Kit,12V 24V Automotive Circuit Tester Car Electrical System Test Tool Kit,AC DC Resistance Digital Voltage Tes

Widely ApplicationThe AUTOOL BT260 circuit tester Suitable for all 9V to 30V automotive electrical system diagnostics can perform all types of tests such as Dc voltage test, Ac voltage test, resistance and diodes test etc It adopts the newly improved functions to test signal frequency, and duty cycle, which can help service technicians track and identify problem circuits as well as rule out bad ones, speeding up the diagnostic process and making it easier to find the true cause of a circuit problem continuity TestAUTOOL BT260 circuit tester can carry out continuity test Test Procedure: Unfold the cable and connect the red clip to the positive end of the vehicle battery and the black clip to the negative end of the vehicle battery connect the auxiliary ground wire to one side of the test lead and the probe tip to the other sidef there is continuity in the vehicle circuit, the LED will glow green If the LED does not glow, there is no continuity Voltage and Polarity TestWhen the AUTOOL BT260 circuit tester is in the Dc voltage mode, contact its probe tip to the positive circuit The LED should glow red and the LcD display will show the voltage data If the tools buzzer is turned on, a high-pitched tone will sound contact probe tip with the negative circuit, the LED should glow green and the LcD display will show voltage data If the tools buzzer is turned on, a low tone will sound Neither LED will glow if its probe tip is connected to an open circuit Signal circuit TestThe AUTOOL BT260 circuit tester can easily test vehicle sensors For example, a user who suspects a problem with the MAP sensor circuit can follow the procedure related to testing this sensor as follows : Set the BT260 to Ac voltage mode, connect the grounded wire clip to the MAP sensor negative terminal, then connect the probe tip to the MAP sensor positive terminal and check the LcD display Activate components in the VehicleIf the green LED light turns off or the circuit breaker trips suddenly, it indicate View full description
