tm:01min 00s 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 section of Store, Recall and
Clear Operation.
Note:
• Breakdown is detected when the measured current reaches or exceeds the set current level
trigger.
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.
