Timer information
Measuring procedure:
-
Connect the test leads to the instrument and to the measured object.
-
Press
the
START/STOP
key to start the measurement.
- Wait until the set timers run out or until breakdown occurs, (the result will be
displayed).
-
. Wait for the object under test is discharge.
-
The result can be saved by pressing the
MEM
key twice, see the chapter 6.1 Store,
Recall and Clear Operation.
Note:
-
Breakdown is detected when the measured current reaches or exceeds the set
current level
Itrig
.
Notes:
-
The timer shows the time needed to complete each step during the measurement
and it shows the total measurement period after the completion of the measurement.
-
A high-voltage warning symbol appears on the display during the measurement to
warn the operator of a potentially dangerous test voltage.
