Before taking a continuity test, make sure that power to the device or circuit under test

is off and that all capacitors are discharged.

2.

Touch the test tips to the device under test.

3.

If the resistance is less than 200k

Ω, the tester will sound an audible alert; the LCD will

display “000”, and the

continuity LED will light.
