c. At Range 400Ω, short-circuit the test lead to measure the wire resistance, and then subtract it
from the real measurement.

12. Diode and Continuity Test
1. Turn the function/ range selection knob to “ ” Range. Insert the red and black test lead
separately to V
Ω
Hz and COM input terminal. Press “SELECT” button to choose the Buzzer and Diode
measurement function, displayed as the right pictures.
2.
Connect the RED test lead to the positive pole of the tested diode, BLACK test lead to the
negative pole.
3.
Read the present test result from LCD.
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 ciruit 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.
