Produkt of the month – ELECTRIC MULTIFUNCTION TESTING UNITS

Now immediately available at Leitenberger

Our testing units AZ 172 to AZ 176 are the real deal when it comes to testing electrical components and shortening the test and diagnostic time in the workshop. The application possibilities are manifold: Assemblies from 6 - 48 volt can be precisely examined, for example.

Thanks to the integrated lighting* in our testing units, dark test points are optimally illuminated. The infinitely resettable short-circuit fuse with 7.5 A ensures accident-free working.


Our testing units allow users to perform the following tasks in the workshop, regardless of whether the component is built-in or disassembled:

  • Continuity checks on wiring harnesses, switches or fuses.
  • Detect faulty ground connections without time-consuming voltage drop test.
  • Measure DC voltage, pulsed voltage and voltage peaks.

Depending on the device version, the polarity of the tested components is signalled both optically via LED or LC display and acoustically via two different signal tones.
The standardised cable length of 6 m ensures that our testing units can also easily reach and test trailer lights or trailer sockets.
