Auto Power Off
Auto Power Off is a battery saving feature that puts the meter into a sleep mode if
the Function/Range Switch has not changed position in the last 30 minutes. To
wake the meter turn it off and then on.
The Auto Power Off feature can be disabled to keep the meter from going to sleep.
This feature is useful when using the MIN MAX mode for extended periods. To
disable the Auto Power Off feature use the following procedure:
1.
Set the Function Switch to OFF .
2. Press and hold the MIN MAX button while turning the Function Switch to the
desired function.
3. Continue to press the MIN MAX button until the display finishes this
initialization period and the reading settles.
4. Release the MIN MAX button. The Auto Power Off feature will remain disabled
until the meter is turned off and then on.
HOLD Measurements
The HOLD button causes the meter to capture and continuously display a
measurement reading. To use the HOLD feature make a measurement, and then,
after the reading has stabilized, momentarily press the HOLD button. You can
remove the test leads and the reading will remain on the display. Pressing the
HOLD button again releases the display.
Backlight
Pressing the
L
button illuminates the display with a blue backlight. The backlight
will automatically turn off in about 60 seconds. Frequent use of the backlight will
decrease battery life.
