Resistance Measurement,



➭

Disconnect supply power from the electrical circuit of the
device to be measured, and discharge all high-voltage
capacitors.

➭

Make sure that the device under test is voltage-free.
Interference voltages distort measurement results!
Refer to chapter 5.1.1 regarding testing for the absence of
voltage with the help of the direct voltage measurement.

➭

Set the rotary switch to “



”.

➭

Connect the device under test as shown.

Note

Use short or shielded measurement cables in the case of
high-impedance resistance.

Improving Accuracy by means of Zero Balancing

Cable resistance and contact resistance can be eliminated in all
measuring ranges by means of zero balancing (see chapter 4.2).
