of the display indicating that the memory has been cleared.

memory.

ALL OPERATIONAL DIFFICULTIES
If this meter does not function properly for any reason, replace the battery
with a new high quality battery (see the “Battery Replacement” section). Low
battery power can occasionally cause any number of “apparent” operational
difficulties. Replacing the battery with a new fresh battery will solve most
difficulties.

BATTERY REPLACEMENT
An erratic display, faint display, no display, or battery symbol appearing on
the display are all indicators that the battery needs replacement. Slide the
battery cover off the back of the meter in the direction of the arrow. Remove
the exhausted battery and replace it with a new 9 volt alkaline battery.
Replace the battery cover.
