Operation
Preparation and safety measures
Installing the battery
Before using the instrument, the battery must be installed. This is carried out as fol-
lows:
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 a new battery (type 1.5 V IEC LR6), taking care that the polarity is correct. Ma-
kesure that no wires are trapped between the 2 halves of the housing, and close
itagain
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,
especially 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.
