Testing for Continuity
To avoid possible damage to your multimeter or to the equipment under test, disconnect
CAUTION
the circuit power and discharge all high-voltage capacitors before testing for continuity.
Set up your multimeter to test for continuity as shown in Figure 2-15. Probe the test points
and read the display.
Table 2-7
Legend
The continuity test features a beeper that sounds and a red LED that turns on as long as a
NOTE
circuit is incomplete or broken. The audible and visual alert allow you to perform quick
continuity tests without having to watch the display.
In continuity, a short means a measured value is less than the threshold resistance values
listed in Table 2-8.
