6511A12-24V Multi-function Auto Tester with LED Display


The equipment used to test the automotive electrical system within 12 -24V.
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. For the testing and safety purpose, this unit contains short-circuit protection, which can also check the ground connection without voltage drop tests. The short-circuit protection system contains the recoverable fuse, so the technician will not waste the fuses during the testing.


  • Peak detection.
  • With CE Approval.
  • Locate missing cylinders.
  • Illumination for dark operation.
  • Testing the continuity of the circuit.
  • Determine the polarity and circuit circumstance (short/ open).
  • Activating the components with positive or negative current without jumper wire.
  • Testing the voltage of the circuit and the voltage reading will be indicated on the LCD display within 1/10th of a volt.
  • Measuring frequency of the high-tension ignition pulses and we could calculate the rotational speed of engine according to the measured frequency.
