JLH-822 calibration instructions – Revised 02/07/02

The links below contain the instructions for calibration of the JLH-822 dual channel
octave and semitone voltage switcher. You will find the assembly instructions in a
separate document. See the instructions page. You may also want to check out the
theory of operations document to better understand the circuit. Please e-mail me
Larry Hendry if you find any errors or have any comments or questions about this
documentation. Of course, you can right click and use "save target as" to download
these files.

There are three basic methods of calibration.

Calibration instructions for these first two methods are listed below. You need only one.
If you choose the tuner method, down load the ear method to see which trimmers to
operate. However, I did not write instructions for using a tuner. I imagine you can figure
that out on your own.
