CONT LED will light up to indicate continuity (line resistance
must not exceed 10 kilo-ohms)
Set the Sender to TONE
•
Connect the leads to a pair of wires you want to test.
•
At the other end, press and hold the button on the Receiver and
touch the wand to each connected wire. The Receiver will sound
a tone to indicate continuity.
