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.
