4. DIRECTIONS FOR USE
4.1 Automatic recognition mode
• Press the FUNC. key for more than one second to start up
the tester and enter automatic recognition mode . The
device then automatically detects the nature of the
component - resistor, (ohm), capacitor (F), or diode - or
performs a continuity test.
NOTE :
• Ranges in automatic recognition mode:
Resistor: 600.0 Ω~ 6.000 MΩ;
Capacitor: 6 nF ~ 600 µF.
4.2 Resistor measurement
When the component is part of a circuit:
- disconnect all power sources and discharge the
capacitors before the measurement
- the measurement can be thrown off by the
presence of adjacent components.
• Press the FUNC. key and select the mode.
• Connect the test clip to the component to be measured; the
measured value will appear on the display unit.
NOTE :
• The RANGE key is available in this mode.
• When the clip is not connected, or poorly connected, in other
words open-circuit, the “OL” indication is displayed to report
an overshoot of the range.
• If the measurement is rendered inaccurate by the presence
of external components: it will be necessary either to isolate
the component to be tested or to compare the results to
those obtained on a reference circuit.
4.3 Capacitor measurement
When the component is part of a circuit:
- disconnect all power sources and discharge the
capacitors before the measurement
- the measurement can be thrown off by the
presence of adjacent components.
• Press the FUNC. key and select the mode.
• Connect the test clip to the capacitor to be measured; the
measured value is displayed.
NOTE :
• The RANGE key is available in this mode.
• Discharge the capacitor before making a measurement.
• If the measurement is rendered inaccurate by the presence
of external components: it will be necessary either to
isolate the component to be tested or to compare the
results to those obtained on a reference circuit.
4.4 Diode test
When the component is part of a circuit:
- disconnect all power sources and discharge the
capacitors before the measurement
- the measurement can be thrown off by the
presence of adjacent components.
• Press the FUNC ; key and select the mode.
• Connect the + probe tip of the tester to the anode and the
- probe tip to the cathode of the diode to be measured.
• The tester will display the approximate forward voltage of
the diode. When the connection is reversed, the “OL”
indication is displayed (if the diode is functional).
• If the measurement is rendered inaccurate by the presence
of external components: it will be necessary either to
isolate the component to be tested or to compare the
results to those obtained on a reference circuit.
4.5 Continuity test
• Press the FUNC. key and select the mode.
• Connect the test clip to the circuit to be tested. When
there is continuity (in other words, a resistance of less
than 30 Ω), the buzzer in the device sounds.
5. AUTOMATIC SHUTDOWN
• In order to increase the battery life, the device has an
automatic shutdown function. If no key is pressed for
10 minutes, the tester automatically switches itself off.
6. MAINTENANCE
6.1 Cleaning
• Use a soft cloth, dampened with soapy water. Rinse
with a damp cloth.
• Dry thoroughly with a dry cloth or forced air before
using again.
6.2 Replacing the batteries
When the , symbol is displayed, the batteries must
be replaced.
Proceed as follows
• Press on the cover of the battery compartment and
push as shown by the arrow to open.
• Replace the two batteries with two new 1.5 V batteries
(AG13 / LR44 / 357A / etc.).
• Put the cover of the battery compartment back in
place.
6.3 Metrological check
Like all measuring or testing devices, the instrument must
be checked regularly.
This instrument should be checked at least once a year.
