5.2.2 7 mA resistance measurement
In general this function serves as standard
-meter with low test current. The
measurement is performed continuously without pole reversal. The function can also be
applied for testing continuity of inductive components.

Continuous resistance measurement procedure
Select the
CONTINUITY
function.
Set sub-function
R 7mA (L-PE or N-PE).
Enable and set
limit
(optional).
Connect
test cable to the instrument.
Compensate
test leads resistance (if necessary).
Disconnect
from mains supply and discharge tested object.
Connect
test leads to the tested object (see
figure 5.8
).
Press the
TEST
key for continuous measurement.
Press the
TEST
key to stop measurement.
After the measurement is finished
store
the result (optional).
