3 Usage
Do not exceed the maximum input values. Extreme caution should be used when
voltages higher than 25 VAC or 35 VDC could be present.
When testing is complete, turn the rotary dial to the off position.
To wake the tester from Auto Power Off (APO) mode press the select button >3 seconds.
3.1 Voltage
Turn the rotary dial to the voltage position. Ensure the test leads are connected to the
correct meter terminals. Use the select button to toggle between VAC and VDC as
required. Connect the two test probes to the object / circuit to be measured. The
measured value is then displayed on the LC display.
When measuring VDC the red probe indicates the positive pole and the black probe the
negative pole. If a minus is displayed on the LC display the measured voltage is negative
polarity.
3.2. Non Contact Frequency (NCF) 50/60Hz
Turn the rotary dial to the voltage AC position. Press the Hz / % button, Hz will be shown on
the LC display. Insert the red test lead into the positive terminal of the meter. Now move
the NCV / NCF sensor towards the socket / cable to be tested. The measured value will
be indicated on the LC display.
3.3 Resistance
Ensure that the component to be measured is safely isolated from any voltage source.
Turn the rotary switch to the resistance setting. Ensure that the test leads are connected to
the correct meter terminals. Check the test leads for continuity by touching the probe tips
together. The value must be approximately 000.0Ω. If the reading is not zero press REL to
adjust to zero. Connect the probes across the object to be measured ensuring a good
clean contact, as long as the object to be measured is not high resistance or interrupted
the measured value will be displayed on the display. If OL is displayed the measuring
range has been exceeded or the measuring circuit has been interrupted.
3.4 Diode Test
Ensure that the diode to be measured is safely isolated from any voltage source. Turn the
rotary switch to the diode setting. Ensure that the test leads are connected to the correct
meter terminals. Connect the test probes to the diode to be tested. The display shows the
forward voltage. If OL is displayed the diode may be being measured in the reverse
direction or it may be faulty.
3.5 Continuity check
Ensure that the component to be measured is safely isolated from any voltage source.
Turn the rotary switch to the continuity setting and press the select button. Ensure that the
test leads are connected to the correct meter terminals. Check the test leads for
