6.11 Continuity Test
Warning: Do not perform continuity tests before removing the power from capacitors
and other devices under test during a measurement. Injury to persons can occur.
1.
Refer to Fig. 6-4. Set the function switch to the continuity position.
2.
Short press the MODE button to select continuity if necessary
.
3.
Insert the black probe lead into the negative COM terminal and the red probe
lead into the positive terminal.
4.
Touch the tips of the probe across the circuit or component under test.
If the resistance is < 30Ω the meter beeps
If the resistance is > 480Ω the meter will not beep
If the resistance is > 30Ω but < 480Ω the beep stops at an unspecified point
6.12 Diode Test
Warning: Do not perform diode tests before removing the power to the diode or other
devices under test during a measurement. Injury to persons can occur.
1.
Set the function switch to the diode position. Short press the MODE button to
select the diode test function
if necessary.
2.
Insert the black probe lead into the negative COM terminal and the red probe
lead into the positive
terminal.
3.
Touch probe tips across the
diode or semiconductor
junction under test in one
polarity (direction) and then
in the opposite polarity as
shown in Fig. 6-5.
4.
If the reading is between
0.400 and 0.800V in one
direction and OL (overload) in
the opposite direction, the
component is good. If the
measurement is 0V in both
directions (shorted) or OL in
both directions (open), the
component is bad.
