11-3. Automatic frequency setting

The automatic frequency setting function allows the controller to find the optimum resonance point when the resonance point of the vibrator is unknown.

It is a convenient function.

First, you need to have a vibration sensor, set the proper voltage after connecting the vibrator, and proceed.

If there is no vibration sensor or the output voltage is set too low, the resonance point can not be found.

Set to frequency automatic setting mode.

The automatic frequency setting is about 6 minutes. If you press the "STOP" button, it will stop.
