Frequency Counter

Most meters don’t have a built in function generator but they do have a frequency counter.

The make and model would make it easier to Google the operators manual.


If you can believe the photo HERE, it's a signal generator. Put a crystal earpiece or piezo element between the probes and you may hear a tone; Probably 1KHz. You can use this for injecting an audio signal when you're debugging an amplifier circuit or similar.
