1.Insert the black and red test leads into the COM and
VHz input terminals respectively.
2.Set rotary switch at desired Ωposition.
3.Push F.FUNC. button to select .
4.If the resistance being measured exceeds the
maximum value of the range selected or the input is
not connected, an overrange indication “OL” will be
display and the higher range has to be selected.
5.Read the measure result directly from the display.
7.4 RESISTANCE MEASUREMENT
1.Insert the black and red test leads into the COM and
VHz input terminals respectively.
2.Set rotary switch at desired Ωposition.
3.Push F.FUNC. button to select .
4.The red lead should be connected to the anode and
the black lead to the cathode of the diode.
5.The typical voltage drop should be about 0.6V for
silicon diode or 0.3V for germanium diode.
6.If the diode is reverse biased or there is an open
circuit the reading displayed will be “OL”.
7.5DIODE MEASUREMENT
7.6 CONTINUITY TESTING
1.Insert the black and red test leads into the COM
and VHz input terminals respectively.
2.Set rotary switch at desired Ωposition.
3.Push F.FUNC. button to select .
4.If continuity exists (i.e., resistance less than 30)
built – in buzzer will sound.
If the resistance being measured exceeds the maximum
value of the range selected or the input is not connected,
an overrange indication “OL”will be displayed.
NOTE:
When checking in-circuit resistance, be sure the circuit
under test has all power removed and that all capacitors
have been discharged fully.
For measuring resistance above 1M, the meter may take
a few seconds to get stable reading. This is normal for
high resistance measurements.
When the input is not connected, i.e. at open circuit, the
figure “OL” will be displayed for the overrange condition.
7.7 CAPACITANCE MEASUREMENT
1.nsert the black and red test leads into the
COM
and
VHz
input terminals respectively.
2.Turn the rotary switch to position.
3.Connect test leads across the capacitor under
measurement and be sure that the polarity of
connection is observed (Note: The polarity of the
red lead connection is positive “+”).
4.Read the measure result directly from the display.
7.8 MEASURING FREQUENCY
NOTE:
The input voltage should be between 1V and 10V rms.
ac. If the voltage is more than 10V rms. Reading may
be out of the accuracy range.
1.Insert the black and red test leads into the
COM and VHz input terminals respectively.
2.Set rotary switch at desired Hz position.
3.Push % Hz. button to select frequency mode and
connect the test lead tips in parallel with the circuit
to be measured. Be careful not to touch any
electrical conductors.
4.The signal amplitude must also be greater than the
sensitivity level.
5.Determine that the amplitude level of the signal to
be measured is not greater than the input voltage
limit (250V DC/AC rms.).
6.Read the measure result directly from the display.
