3.5 Equipotential bonding check
In the "equipotential bonding check" mode the resistance of an equipotential bonding conductor is
measured.
In the bonding conductor measurement the meter generates a test current of up to 1A. This high
test current loads the bonding conductor accordingly so that conductor faults can be detected. The
test voltage generated for this is respectively low so that the measurement does not create a
hazard.

- the specifications of the vehicle manufacturer
- specifications according to ECE Regulation R 100
4. The AVL DiTEST HV Safety 2000 zero adjustment is carried out:
- Place the tips of the probe at the 0-ohm zero point marker aid (blue cable clip)
- Press and hold the test button on the red test adapter until the zero adjustment has completed
- The result of the zero adjustment is displayed
If Kelvin terminals are use, there is no need for zero adjustment. Please press F5 Skip .
