Testing for Continuity

Set up your multimeter to test for continuity as shown in
test points and read the display.
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.
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.
In continuity, a short means a measured value is less that the threshold resistance
