OPERATION
CAUTION! To avoid the risk of electric shock, disconnect the test leads and switch off the meter before opening the
casing.
Safety instructions
Do not operate the meter in an atmosphere with excessive humidity or in the presence of toxic or fl ammable vapours,
or in an explosive atmosphere. Before each use, check the condition of the meter and the test leads. If you notice
any faults, do not start its operation. Replace damaged cables with new ones, devoid of defects. In the case of any
doubts, you should contact the manufacturer. During measurement the test leads should be held by the insulated
parts. Do not touch the measurement points or unused measuring jacks of the meter. Disconnect the test leads before
changing the measured quantity. Never carry out maintenance work without ensuring that the test leads have been
disconnected from the meter and that the meter itself has been switched off .
Replacing the battery
The multimeter requires batteries, the number and type of which are specifi ed in the technical specifi cations. It is rec-
ommended to use alkaline batteries. To install a battery, open the instrument casing or the battery compartment cover
on the underside of the meter. Before accessing the battery compartment it may be necessary to slide off the cover of
the meter casing. Connect the battery according to its terminal marking, close the casing or battery compartment cov-
er. If a battery symbol appears on the screen, the battery must be replaced. For the sake of measurement accuracy,
it is recommended to replace the battery as soon as possible after the battery symbol appears.
Fuse replacement
The instrument uses a fast-acting safety fuse. In case of damage, replace the fuse with a new one with identical
