The Enersave
TM
Mode
Enersave
TM
conserves battery life by reducing the test time from 100 seconds to approx.
10 seconds. Enersave
TM
is the default mode of operation. To disable Enersave
TM
press
and hold the
ON / TEST
button for three seconds to begin a test.
Bargraph Voltage Display
The bargraph represents the voltage present on the test leads as it charges, soaks, and
discharges. The bargraph appears on the lower portion of the display during tests.
Automatic Low Resistance Detect
If the display shows the message “LOW M
Ω
”, the test should be interrupted immediately
by pressing the
ON / TEST
button. This message indicates that the insulation under test
has broken down and the meter is trying to inject a high potential onto a short circuit.
Elapsed Timer
The test duration is indicated on the display. This is particularly useful in determining
whether an insulating material under test will break down in a given amount of time.
Manual Test STOP
To stop a test in progress, press the
ON / TEST
button. The test will immediately end and
the system will automatically discharge.
Automatic Test STOP
The test automatically stops after 100 seconds if the meter is not in the Enersave
TM
mode.
When in the Enersave
TM
mode, the test automatically stops after approx. 10 seconds.
Live Circuit Warning
If the test leads are connected to a live circuit when testing, a warning beeper will sound
and the meter will display “Live Warning…Circuit Live…”. In this case, correct the problem
and retest.
Automatic Discharge
At the end of a test, the meter automatically discharges the high voltage. The automatic
discharge status is reflected on the display. During discharge the beeper will sound and,
when completely discharged, the HOLD icon appears on the display.
Auto OFF
The meter will automatically turn off after approximately 30 minutes of operation.
