MI 3103 GigaOhm Measurements

4.3 Rcon
Rcon function is used when there are inductive loads to be tested, for example motor
windings, transformers, etc, or if there is no need to follow prescribed standards. It can
also be used as an ordinary multi-meter (resistance range).
Test current of only up to 7 mA is used.
For additional general information concerning continuity measurement, refer to the
handbook
Measurements on electric installations in theory and practice
.
Warning!
Make sure the tested item is de-energised (mains voltage disconnected)
before starting the measurement! Fuse will blow if the test probes are
connected to mains voltage during the test.
How to carry out the measurement:
-
Select
Rcon
function with the rotary switch knob.
-
Make sure the test leads are compensated, see the instructions in the chapter 4.4.
-
Connect test leads to the tested item in accordance with figure 7.
-
Press the
TEST
key and read the Rcon resistance result.
-
A double press of
TEST
key starts the continuous measurement. The measurement
is concluded after pressing the
TEST
key again. The latest result will stay on the
display.

test result
Notes!
If an external voltage higher than 10 V AC/DC is present at the test terminals, the
Rcon
measurement will not be carried out after pressing the START key. Symbol
! will be displayed.
If indication
FUS
appears, replace blown fuse. See paragraph 5.3. Fuse
replacement.
Positive pole of test voltage is attached to the red test terminal.
