WARNING 3. Test Lead Detachment
Detach test leads from measuring circuit before changing measurement functions or
removing rear cover for battery or fuse replacement.
3-3. GENERAL WARNINGS AND CAUTIONS
WARNING 1. Children and the persons who do not have enough knowledge about
electric measurements must not use this instrument.
WARNING 2. Do not measure the electricity naked or barefooted to protect yourself
from electrical shock hazard.
WARNING 3. Be careful not to get hurt with the sharp test lead pins.
CAUTION 1. Do not polish the case or attempt to clean it with any cleaning fluid like
gasoline or benzine. If necessary, use silicon oil or antistatic fluid.
CAUTION 2. Away the instrument from hot and humid conditions like in the car. Do not
apply hard mechanical shock or vibration.
CAUTION 3. Remove the battery when the instrument is out of use for a long time. The
CAUTION 4. exhausted battery might leak electrolyte and corrode the inside.
