The unit of measure selected will be the default
unit of measure until changed.
HOLD FUNCTION
The hold function allows the readings on the dis-
play to be "frozen" so that they may be recorded.
1. Press and release the HOLD button to "freeze"
the display at the current reading. "HOLD" will
appear at the bottom of the display.
2. Once the reading has been recorded, press and
release the HOLD button to return the display
to the current reading. "HOLD" will no longer
appear on the display.
DISPLAY MESSAGES

measurement range of the meter, " - - - -" will ap-
pear on the display.
ALL OPERATION DIFFICULTIES
If this meter does not function properly for any
reason, replace the batteries with new, high quality
batteries (see the "Battery Replacement" section).
Low battery power can occasionally cause any
number of "apparent" operational difficulties.
Replacing the batteries with new fresh batteries will
solve most difficulties.
