5.2 Resistance Measurement
Ð Disconnect supply power from the electrical circuit of the de-
vice to be measured, and discharge all high-voltage capaci-
tors.
Ð Make sure that the device under test is voltage-free. Interfer-
ence voltages distort measurement results!
Refer to section 5.1.1 regarding testing for the absence of volt-
age with the help of the direct voltage measurement.
Ð Set the rotary switch to “”.
Ð Connect the device under test as shown.
Note
Use short or shielded measurement cables in the case of
high-impedance resistance.
: “0 L” appears at the display in the case of an open connection.
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 section 4.2).
