Battery Replacement
REMOVE THE TEST LEADS FROM THE METER
BEFORE REMOVING THE BATTERY CASE TO AVOID
ELECTRICAL SHOCK AND INJURY.
WARNING:
1.Replace the batteries once the display shows“ ” to
avoid false readings.
2.Remove test leads and unscrew the battery cover and
remove the cover.
3.Replace the used battery with a new one.
4.Replace the battery cover and tighten the screw.
Maintenance
General Maintenance
• To avoid possible electric shock or personal injury,
repairs or servicing not covered in this manual should be
performed only by qualified personnel.
• Before opening the meter, remove test leads from all
circuits to avoid damage to the meter or personal injury.
• To avoid electrical shock, remove test leads from input
jacks before cleaning.
• To avoid false readings that could lead to possible
electric shock, replace the batteries as soon as the low
battery indicator “ ”appears.
• Clean the instrument case with a damp cloth and mild
detergent. Do not use abrasives or chemical solvents.
• Keep in mind the internal capacitors may retain
dangerous voltages even when the instrument is turned
off.
• Remove the batteries if the meter is not going to be used
for an extended period of time.
