Step 5

Check the displayed warnings and online voltage/terminal monitor before starting mea-
surement. If OK, press the TEST key. After performing, the measurement results appear
on the display together with the PASS/FAIL indication (if applicable).

Fig. 5.8: Example of LowΩ resistance measurement results

Displayed results:
R:

Main LowΩ resistance result (average of R+ and R- results)

R+:

LowΩ resistance sub-result with positive voltage at L terminal

R-:

LowΩ resistance sub-result with positive voltage at N terminal.

Save displayed results for documentation purposes. Refer to chapter 6.1 for further information on
setting functions and saving of measurement results (BENNING IT 120 B only).

Warning:

- LowΩ resistance measurement should only be performed on de-energised objects!

- Parallel impedances or transient currents may influence test results.

Note:
-

If voltage between test terminals is higher than 10 V the RlowΩ measurement will not be performed.

5.2.2 Continuity testing (CONTINUITY)

Continuous lowΩ resistance measurement is performed without pole reversal of the test voltage

and a lower test current (few mA). In general, this function serves as an ordinary Ω-meter with low-
test current. The function can also be used to test inductive components.

How to perform Continuity measurement:
Step 1

Select R

LOW

-Ω , DURCHGANG/ CONTINUITY with the function selector switch. Use the

keys to select the Continuity function. The following menu is displayed:
