Battery Replacement

When the low battery symbol appears on the LCD, replace the
meter’s battery (9V). The battery compartment is located behind
the panel that surrounds the meter’s trigger (see diagram).

Open the compartment by carefully pulling the panel down away
from the trigger area. The panel is hinged at the bottom and
does not completely disconnect from the meter. Replace the 9V
battery and close the battery compartment cover.

Note that the dip switches for TEST LOCK ON/OFF, UNIT OF
MEAUSURE C/F selection, and AUDIBLE ALARM ON/OFF,
explained earlier in this User Guide, are located in the battery
compartment behind the battery.
