3. Before measuring in-circuit resistance, make sure that
the circuit under test has all power removed and all
capacitors are fully discharged.
Continuity Test
1. Connect the black test lead to the
"
COM
"
jack and the
red test lead to the
"
V Hz
"
jack (Note:The polarity of
the red lead is positive
"
+
"
) .
2. Set the range switch to
"
"
position.
3. Press the
"
Select
"
button to make the display show
"
".
4. Connect the test leads to the circuit to be measured.
5. If the circuit resistance is less than about 20 , the
built-in buzzer will sound.
If the circuit resistance is more than about 70 , the
buzzer will not sound.
If the circuit resistance is between 20 and
70 , the
buzzer may sound or may not sound.
If the circuit resistance is more than about 600 , the
display will show
"
OL
"
.
Note :
Before performing in-circuit continuity test, make sure that
the circuit under test has all power removed and all
capacitors are fully discharged.
