Do not operate the multimeter when it is open, when the battery compartment is open, or the battery
compartment lid is missing. The safety mechanism prevents the opening of the battery and fuse lid
when test leads are plugged into the measurement sockets. It also prevents test leads from being
plugged in when the battery and fuse lid is open.
Measurements in damp rooms or under unfavourable environmental conditions are not permitted.
Unfavourable environmental conditions are: dampness or high humidity, dust and
fl ammable gases,
vapours or solvents, as well as thunderstorms or similar conditions such as strong electrostatic fi elds,
etc.
Use only test leads or measurement accessories which meet the speci
fi cations of the multimeter.
