The 6000 counts digital automotive multimeter is well designed with convenient operation, accurate reading, true RMS, clear full symbol LCD display and complete functions. It can measure DC/AC voltage, DC/AC current, resistance, capacitance, frequency, temperature, speed, closing angle, lamp test, positive and negative pulse, crystal diode, triode parameters and circuit on and off, which is very suitable for vehicle maintenance and debugging. Features: Multiple Measurement Functions: includes the measurement of dwell angle, rotational speed, duty cycle, DC/AC voltage, DC/AC current, resistance, capacitance, frequency, temperature, battery, positive and negative pulse, NCV measurement and test lamp measurement, and transistor hFE test, diode test, and on-off test. Data Hold Function: locking the measured data for conveniently read and record. More Features: low battery indicator, 15 minutes auto-off function, probe pen slot designed and supporting bracket. LCD Display with Backlight Function: 6000 counts clearly full symbol LCD displayed, manual on/off the backlight of the multimeter for easily check the readout in the dark environment. Equipped with Protective Cover: in addition to the protection of the tester, but also can support the tester from multiple angles, convenient for observation. Practical & Functional Tester: tester uses the latest software and technology, Features of automatic calibration, high precision, and good stability, which can be widely used in the testing and maintenance on the vehicle.
