Note:
a) Before testing, discharge the capacitor by shorting its leads
together. Use caution in handing capacitors because they may
have a charge on them of considerable power before discharging.
b) Before testing, press “
REL
△
” key to eliminate the zero error.
c) When testing 4000µF capacitor, note that there will be approx.
30 seconds time lag.
3.6 Diode and Audible continuity Test
1) Set the selector switch to desired “
” position.
2) Connect the black test lead to "
COM
" socket and red test lead
to the "
VΩHz
" socket.
3) Press “
SELECT
” key to choose
Diode
or
Audible continuity
measurement.
4) Connect the test leads across the diode under measurement,
display shows the approx. forward voltage of this diode.
5) Connect the test leads to two point of circuit, if the resistance is
lower than approx. 100Ω, the buzzer sounds.
Note:
Make sure the power is cut off and all capacitors need to be
discharged under this measurement.
3.7 Frequency and Duty cycle measurement
1) Set the selector switch to desired “
Hz
” position.
2) Connect the black test lead to "
COM
" socket and red test lead
to the "
VΩHz
" socket.
3) Press “
Hz/DUTY
” key to choose
Frequency
or
Duty cycle
measurement.
4) Connect the probe across the source or load under
measurement.
5) Read the result from the LCD panel.
