Preparation and safety measures
Installing the battery
Before using the instrument, the battery must be installed. This is carried
out as follows:
1) Separate the instrument from any circuit, and remove the test leads.
2) Open the housing by removing the screw on the rear face.
3) Fit the new batteries (2 type 1.5 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.
4) 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 unit under test (UUT).
• Before switching to a new function, the probes must always be removed
from the UUT.
• Use the instrument only in clean and dry surroundings. Dirt and moisture
reduce the effectiveness of the insulation, with consequent danger of
electric shock, specially when dealing with high voltages.
• Use the instrument only in the specified ranges. Before making
measurements, verify that the instrument is functioning properly, for
example by testing on a known voltage or current. Make sure that the
test leads are undamaged.
