l Replace the battery as soon as the battery
indicator" "appears. With a low battery,
the Meter might produce false readings
that can lead to electric shock and personal
injury.
l Turn off the Meter once finished measuring.
Fetch out the battery, when the meter will
not be used for long period.
l Do not operate the Meter under adverse
environmental condition including high
temperature and especially humid area as
the Meter's function may be effected after
moisturizing.
l To avoid damages and dangerous, do not
change the circuit on your own.
l Periodically wipe the cabinet with a damp
cloth and mid detergent. Do not use
abrasives or solvents.
l Dispose the used battery proper.
l International Electrical Symbols.
