I have a Heathkit ET-3100 electronic design experimenter that has a very
basic sine/ square wave function generator. Controls all analog and no
scale really. Output is from 200 Hz - 2 Khz on "low" and 2 Khz to 20
Khz on "high". Exact frequency depends on where the pot is adjusted.
How can I calibrate this to be more precise, preferably in a simple way?

** Time to get a Digital Multimeter with a frequency range.
Not crazy expensive and damn useful.

Plus very accurate.
