gers, warnings, cautions, and notes.

CAUTION
Before and after hazardous voltage measurements, test the voltage function on a known
source (such as line voltage) to determine proper meter functionality.
5.1 Powering the Meter
Set the function switch to any position to power the meter ON.
If the low battery voltage warning is displayed, or if the meter does not power
ON, replace the batteries. See Section 11,
Maintenance , for battery replace-
ment details.
5.2 Auto Power OFF (APO)
The APO feature switches the meter OFF after approximately 10 minutes (de-
fault) of inactivity. The APO timer can be set from 1 to 99 minutes (see the
Programming Menu section). The meter will beep to alert you when it is about
to power OFF, press any button to extend the APO time before it powers OFF.

The meter uses automatic ranging by default. To manually select a measure-
ment range, short press the RANGE button to exit the Auto mode. Subse-
quent, short presses will step through the available ranges. Long press the
RANGE button to return to the Auto Range mode. When the Auto Range
mode is active, the Auto Range symbol is displayed. In the manual mode, the
meter may display an up arrow, suggesting that a higher range should be se-
lected for best accuracy and resolution.
