R LOWΩ measurement procedure

Select continuity function using the function selector keys.

Set sub-function to
R LOWΩ
using

/

keys.

Enable and set limit (optional).

Connect PV continuity test lead to the instrument.

Compensate the test leads resistance (if necessary, see section 5.2.3 ).

Connect the test leads to the appropriate PE wiring (see Figure 5.6).

Press the TEST key to perform the measurement.

After the measurement is finished store the result by pressing the MEM button
(optional).

Displayed result:
R................R LOWΩ resistance
R+..............result at positive polarity
R-...............result at negative test polarity
U:.............. actual voltage on test inputs
5.2.2 Continuous resistance measurement with low current
In general, this function serves as standard

-meter with a low testing current. The
measurement is performed continuously without polarity reversal. The function can also
be applied for testing continuity of inductive components.
