4.17 MEASURING CAPACITANCE   
    WARNING 
Beware of Electrocution. 
To  avoid  electric  shock,  make  sure  that  the 
capacitors  have  been  fully  discharged  before 
measuring the capacitance of a capacitor. 
4.17.1 Plug the black test lead into the COM jack and the 
red test lead into the    jack. 
4.17.2 
Set the rotary selector to the 
Ω
  range position.
4.17.3 After fully discharged the capacitor, connect the test 
leads  to  the  two  ends  of  the  capacitor  for 
measurement. 
4.17.4 Take the reading on the main indicator of the LCD. 
NOTE: 
1) It may take some time (about 30 seconds for the 200µF 
range)  for  steady  readings  when  measuring  high 
capacity. 
2) Sometimes a reading may appear when the circuit is 
open.    In such case, press the “REL” button to reset 
the reading and take measurement again. 
4.18 TESTING DIODE 
4.18.1 Plug the black test lead into the COM jack and the 
red test lead into the  jack. 
4.18.2 
Set the rotary selector to the 
Ω
  range position.

  OPERATING INSTRUCTION
4.18.3 Press the "SELECT" button to switch to    test. 
4.18.4 Connect the red test lead to the anode and the black 
test lead to the cathode of the diode for testing.   
4.18.5 Take the reading on the main indicator of the LCD. 
NOTE: 
1) The meter will show the approximate forward voltage 
drop of the diode. 
2) When the test leads have been reversed or open, ‘OL’ 
will appear on the LCD. 
4.19 TESTING CONTINUITY   
    WARNING 
Beware of Electrocution. 
Make  sure that  the power of the  circuit has been 
turned  off  and  the  capacitors  have  been  fully 
discharged before testing the continuity of a circuit.
4.19.1 Plug the black test lead into the COM jack and the 
red test lead into the Ω jack. 
4.19.2 
Set the rotary selector to the 
Ω
  range position.
4.19.3  Press  the  “SELECT”  button  to  switch  to    for 
continuity test.   
4.19.4 Connect the test leads to the two ends of the circuit 
for measurement. 
4.19.5 If the resistance of the circuit being tested is less than 
40Ω, the built-in buzzer will sound.
