How to perform a Continuity Test

How to perform a Continuity Test


This is straight from the full owner's manual for the Innova 3320 digital multimeter

1. Connect the Leads.

Plug the RED test lead into the jack on the right of the multimeter; Plug the BLACK test lead into the COM jack on the middle of the multimeter.

2. Set Function/Range Selector

Set the meter’s Function/Range Selector Switch to the Continuity position.
  1. Place the RED Test Lead to one end of the wire or device being tested for continuity and the BLACK Test Lead to the opposite end.
  2. Listen to the sound of the beeper and confirm the results by reading the display.

Note: The beeper will sound only if the continuity of the item under test (resistance between the two test leads) measures less than 120 ohms
