Open circuit voltage: 400mV. Over range protection: 250V AC/DC
peak value.
Diode and Continuity Test
1. Turn the function/range selection knob to
Range, Insert the
red and black test lead separately to VΩHz and COM input terminal.
Press “SELECT” button to choose the Buzzer or Diode
measurement function.
2. Connect the red test lead to the positive pole of the tested diode,
BLACK test lead to the negative pole.
4. Read the present test result from LCD. (Note: no Bar Graph
display at Diode Range)
Note:
a) If the diode is open circuit or the polarity is connected counter,
“OL” will be displayed on LCD.
b) When measuring the in-circuit diode, make sure all the power of
the tested circuit has been turned off and all capacitors are fully
discharged.
c) Cut the connection between the test lead and tested circuit at
once after measurement.
