3.6 Diode And Audible continuity Test
1) Connect the black test lead to
“COM”
socket and
red test lead to the
“V
Ù
Hz”
socket.
2) Set the selector switch to desired
“
Ù
”
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
Ù,
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
Ù
Hz
” socket.
2) Set the selector switch to desired
“Hz”
position
.
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.
3.8 Temperature measurement
1) Connect the black test lead of the sensor to
“COM’
socket and red test lead to the
“V
Ù
Hz”
socket.
2) Set the selector switch to desired “°C/°F” position.
3) Press “SELECT” key to choose “°C” or “°F”
measurement.
4) Put the sensor probe into the temperature field
under measurement.
5) Read the result from the LCD panel.
6) Please use special probe for high temperature test .

3.3 AC Current Measurement
1) Set the selector switch to desired
“400A~
”
or
“3000A~”
position.
2) Press
“SELECT”
key to choose
“AC”
measurement.
3) Disconnect the test leads from the meter.
4) Clamp the Jaws around the
one
conductor to be
measured. Center the conductor within the Jaw
using the Centering Marks as guides.
5) Read the result from the LCD panel.
3.5 Capacitance Measurement
1) Connect the black test lead to
“COM”
socket and
red test lead to the
“V
ÙHz”
socket.
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 handling
capacitors because they may have a charge on
them of considerable power before discharging.
b) Before testing, press
“REL
r
”
key to eliminate the
zero error.
c) When testing 4000
µF capacitor, note that there will
be approx. 30 seconds time lag.
3.4 Resistance Measurement
1) Connect the black test lead to
“COM”
socket and
red test lead to the
“V
ÙHz”
socket.
2) Set the selector switch to desired
“Ù ”
position.
3) Press
“SELECT”
key to choose
Resistance
measurement.
4) Connect tip of the test leads to the points where
the value of the resistance is needed.
5) Read the result from the LCD panel.
Note :
When take resistance value from a circuit
system, make sure the power is cut off and all
capacitors need to be discharged.
