TONE GENERA TOR
Description
The 45081 Tone Generator is intended to trace

Polarity Testing
1. Set the switch to OFF/POL.
2. Strip the wires. Use the alligator clips to
connect the 45081 Tone Generator to the
wires. The LED will glow when the red

this would send a loud warbling tone
to the customer.
