Resistance Measurement,

∞

Disconnect power supply 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 regard-
ing testing for the absence of voltage with the help of the direct 
voltage measurement.

∞

Set the rotary switch to “

Ω

”. 

∞

Connect the device under test as shown.

Note!

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

mproving Accuracy by means of Zero Balancing

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