Step 5 Check for any warnings and the online voltage/terminal monitor on the display
before starting the measurement. If everything is OK, press the TEST key.
After performing the measurement, the results appear on the display together
with the PASS/FAIL indication (if applicable).
Figure 5.8: Examples of Low
resistance measurement results
Displayed results:
R.............Main Low resistance result (average of R+ and R- results),
R+...........Low resistance sub-result with positive voltage at L terminal,
R-............Low resistance sub-result with positive voltage at N terminal.
Warnings:
Low-value resistance measurements should only be performed on de-energized
objects!
Parallel impedances or transient currents may influence test results.
Note:
If voltage between test terminals is higher than 10 V the LOW measurement
will not be performed.
5.2.2 Low current continuity test
Continuous low-value resistance measurements can be performed without pole reversal
of the test voltages and a lower test current (a few mA). In general, the function serves
as an ordinary -meter with low-test current. The function can also be used to test
inductive components such as motors and coiled cables.
For additional information concerning continuity measurements refer to the Metrel’s
handbook Measurements on electric installations in theory and practice.
How to perform low current continuity measurement
Step 1 Select Continuity function with the function selector switch and use the /
keys to select the Continuity sub-function. The following menu is displayed:
