- 10 -
2) Bring the selector (2) into the “µA –mA” sector
always starting from mA.
3) Take the measurement.
CURRENT MEASUREMENT UP TO 10A
This tester is not designed for making alter-
nating current measurements.
! !
Warning! With the socket 10A(5) never
exceed the limit of 10A
! !
1) Connect the red probe to the 10A jack (5)
and the black one to the “COM” jack (3).
2) Turn the dial (2) to the “10A” selection.
3) Take the measurement.
Warning: the tester is protected by a fuse that
could intervene in case of exceeding 10A.
RESISTANCE MEASUREMENT
1) Connect the red probe to the “VΩ” jack (4)
and the black one to the “COM” jack (3).
2) Turn the dial (2) to the “Ω” on the desired scale.
3) Take the measurement.
WARNING: The circuit must always be de-
energised when taking a resistance measu-
rement. Never connect the test leads to a
voltage source; this is dangerous and could
also damage the tool.
CONTINUITY TESTS
! !
WARNING: The circuit on which you want
to run the diode test must be de-energised to
avoid seriously damaging the tool.
1) Connect the red probe to the “VΩ” jack (4)
and the black one to the “COM” jack (3).
2) Turn the dial (2) to DIODE , BUZZER
3) Take the measurement.
You will hear a noise and the LED(6) lights up if
there is continuity in the circuit.
DIODE TEST
! !
WARNING: The circuit on which you want
to run the diode test must be de-energised to
avoid seriously damaging the tool.
1) Connect the red probe to the “VΩ” jack (4)
and the black one to the “COM” jack (3).
2) Turn the dial (2) to DIODE , BUZZER
3) Take the measurement; connect the test leads
to the poles of the diode to be tested. Read the
voltage drop directly on the display in mV. If the
connection is inverted or the diode junction is
open, the display will read “I”.
SQUARE WAVE GENERATOR (50Hz)
1) Connect the red probe to the socket (4) “VΩ”
and the black one to the “COM” (3).
2) Turn the switch (2) in the SQUARE WAVE
sector.
Attention this is a signal output. There is no
protection for the short circuit.
BATTERY REPLACEMENT
Make sure the tool is switched off when installing
the battery (function dial (2) in OFF position).
This will prevent damage to the multimeter if the
battery is incorrectly connected.
Replace the battery when the battery symbol
appears on the display. To replace the
battery, follow the instructions below:
- using a screwdriver, remove the rear battery
compartment cover (16).
- remove the battery and replace it.
- close the compartment cover and tighten the
screws.
FUSE REPLACEMENT
The 10A socket (5) is protected against overload
by a fuse (15) inside the unit.
In case of intervention, reduce current and re-
place the fuse with one with the same features
(not supplied).
To replace the following guidelines:
- Remove the protective case (7)
- With the use of a screwdriver, remove the rear
cover (8)
- Remove the fuse (11) and replace it with one
of equal value
- Close the cover and retighten the screws.
- Mount the protective case.
