How to calibrate a dial

Query Parameters value can be any integer from 0 to 2048.

We are looking for a value for which dial indicator (needle) will be perfectly vertical.

Calibration process:

  1. Send calibration value (ie 600)
  2. Dial will move the indicator
  3. Check the position of the indicator
    4a. If dial indicator is leaning towards left side, go to step 1. and increase the value
    4b. If dial indicator is leaning towards right side, go to step 1. and decrease the value
  4. Repeat steps 1-4 until dial indicator is perfectly vertical

No undo

Dial does not store previous calibration values.
Sending new calibration value will overwrite the previous value.

Caution

All dials come pre-calibrated from the factory.
You should never have to re calibrate them.
