5.3 Diode Measurement
To avoid the meter or measured equipment from
being damaged, cut off all power supply of
measured circuits and discharge all high voltage
capacitors before measuring diode.
Warning
The method of measuring diode is:
1.Turn rotary switch to position.
2.Press key and select measuring range.
3.Separately connect black and red test leads to
negative pole and positive pole of measured diode.
4.The meter shall display forward bias value of
measured diode.If the poles of the test leads are
connected inversely, the meter will display “OL”.
Notice
:
For on-line measuring diode, display forward voltage
drop at forward measurement; the reverse measurement
depends on the values of other elements connected in
parallel at both ends of diode.
5.4 Continuity Measurement
To avoid the meter or measured equipment from
being damaged,cut off all power supply of
measured circuits and discharge all high voltage
capacitors before continuity measurement.
Warning
The method of continuity measurement is:
1.Turn
rotary
switch
to
position,.
2.Press
key
and
select measuring range.
3.Separately connect two ends of test leads to the two
ends of measured part and circuit.
4.The
meter
shall
display
the
approximate
resistance
value
between measured
points.Here
if
the
resistance
value
between
measured
points is
less
than
50±20
Ω
,
the
buzzer
will
make
a
sound.
5.5 Capacitance Measurement
To avoid the meter or measured equipment from
being damaged,cut off all power supply of
measured circuits and discharge all high voltage
capacitors before on/off measurement.
Warning
The capacitance ranges of the meter are:
40.00nF, 400.0nF, 4.000uF, 40.00uF, 100.0uF.
The method of measuring capacitance is:
1.Turn rotary switch to position,
2.Press key and select measuring range.
3.Apply the two ends of test leads to measure the two
pins of the capacitance under test and read measured
value from LCD.
Notice:
1.The meter shall take some time to stabilize the reading
when high capacitance.
2.The small capacitance with less than 10nF shall minus
the distribution capacitance of the meter and lead
(namely displayed base number) when measuring.
