Preparation and safety measures
Fitting the battery
Before using the instrument, the battery must be
fitted. This is carried out as follows:
• Separate the instrument from any circuit, and
remove the test leads.
• Open the housing by removing the screw on
the rear face.
• Fit a new battery (type 9 V IEC LR6), taking care that
the polarity is correct. Make sure that no wires are
trapped between the 2 halves of the housing, and
close it again.
• The instrument is now ready for use.
The selector switch must be turned to the
desired type of measurement before the probes
are connected to the circuit.
Before switching to a new function, the probes
must always be removed from the circuit.
Use the instrument only if clean and dry
surroundings. Dirt and moisture reduce the
effectiveness of the insulation, with consequent
danger of electric shock, especially when dealing
with high voltages.
