2)
Set the selector switch to desired “ ” position.
3) Connect tip of the test leads to the points where the value of the
capacitance is needed.
4) Read the result from the LCD panel.
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 4000
µF capacitor, note that there will be approx.
30 seconds time lag.
3.6 Diode and Audible continuity Test
1) Connect the black test lead to " COM " socket and red test lead
to the " V
ΩHz
" socket.
2)
Set the selector switch to desired “ ” position.
3) P
ress “
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. 100
Ω, 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) Connect the black test lead to " COM " socket and red test lead
to the " V
ΩHz
" socket.
2)
Set the selector switch to desired “
Hz
” position.
3) P
ress “
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.
