Measurement procedure:
-
Connect the test leads to the instrument and to the test object.
-
Select
INSULATION RESISTANCE
function in
MAIN MENU
.
- Press
the
START/STOP
key and release it, continuous measurement will begin.
-
Wait until the test result has stabilized then press the
START/STOP
key again to
stop the measurement or, if enabled, wait for the set timer runs out.
-
Wait for the object under test to discharge.
-
The result can optionally be saved pressing the
MEM
key twice, see chapter 6.1
Store, Recall and Clear Operation.
Legend of displayed symbols:

C=0.0nF
Capacitance of measured object
tm:04min 26s
Timer information – test duration
Bar
Analogue representation of result
Rmax=20.1G
Maximum value of result (only if timer is
enabled)
Rmin=19.9G
Minimum value of result (only if timer is
enabled)
Notes:
-
If the timer is disabled then
OFF
is displayed instead of the timer value.
-
During a measurement, the timer information displays the time needed to the
complete the measurement (tr) while after the completion the test duration (tm) is
displayed.
-
A high-voltage warning symbol appears on the display during the measurement to
warn the operator of a potentially dangerous test voltage.
-
Value of capacitance is measured during the final discharge of the test object.
