Making Measurements 2

Testing for Continuity

Testing for Continuity

Set up your multimeter to test for continuity as shown in

Figure 2- 11. Probe the test points and read the display.

In continuity, a short means a measured value is less that

the threshold resistance values listed in Table 2- 1.

Press to switch between resistance measurement, short

continuity test ( ), or open continuity test ( ). See

Figure 2- 10 to learn more.

CAUTION

To avoid possible damage to your multimeter or to the equipment under

test, disconnect the circuit power and discharge all high-voltage

capacitors before testing for continuity.

NOTE

Continuity is the presence of a complete path for current flow. The

continuity test features a beeper that sounds and a backlight that flashes

as long as a circuit is complete if short continuity is selected (or broken if

open continuity is selected). The audible and visual alert allows you to

perform quick continuity tests without having to watch the display.
