CAPACITANCE MEASUREMENT
1) Set the selector switch to desired “
” position.
2) Connect the black test lead to
“COM”
socket and red test lead to the
“V
W
mA”
socket.
3) Press
“SELECT”
key to choose
Capacitance
measurement.
4) Connect tip of the test leads to the points where the value of the capacitance is nee-
ded.
5) Read the result from the LCD panel.
Note:
a) Before testing, discharge the capacitor by shorting its leads together. Use caution in
handling capacitors because they may have a charge on them of considerable power.
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.
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
“V
W
mA”
socket.
3) Press
“SELECT”
key to choose
Diode
or
Audible Continuity
measurement.
4) Connect the test leads across the diode under test, display measures the approx. for-
ward voltage of this diode.
5) Connect the test leads to two point of circuit, if the resistance is lower than approx.
50
W
, the buzzer sounds.
Note:
Make sure the power is cut off and all capacitors need to be discharged under this
measurement.
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
“V
W
mA”
socket.
3) Press
“Hz%”
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.
