OTC520 Multi-functional Auto Tester
This is an equipment used to test the automotive electrical system within 12-24 volts. In order to save the testing hours for the automotive electrical system, it is designed to testing the system without re-connection between the vehicle battery and the testing components.
Main Functions
- Determine the polarity and circuit circumstance (short/open).
- Activating the components with positive or negative current without jumper wire
- Testing the voltage and continuity of the circuit
- Illumination
- Locate missing cylinders
- Measuring frequency of the high-tension ignition pulses and we could calculate the rotational speed of engine according to the measured frequency.
- Peak detection
- Testing the voltage of the circuit and the voltage reading will be indicated on the LCD display within 1/10th of a volt.
