Testing for Continuity
Caution
To avoid possible damage to the meter or to
the equipment under test, disconnect circuit
power and discharge all high-voltage
capacitors before testing for continuity.
Continuity is the presence of a complete path for current
flow. The continuity test features a beeper that sounds if a
circuit is complete. The beeper allows you to perform
quick continuity tests without having to watch the display.
To test for continuity, set up the meter as shown in
Figure 3.
Press T to turn the continuity beeper on or off.
The continuity function detects intermittent opens and
shorts lasting as little as 1 millisecond (0.001 second).
These brief contacts cause the meter to emit a short beep.
