(trimming potentiometer TP 1: Setting feedback frequency)
The intensity setting is converted to a frequency. This frequency can be measured at Pin 1 AD654 on IC1.
Test point MP6 is reference ground. Frequency is measured using a frequency meter. The setting takes
place at intensity 5 - for this setting the set feedback frequency is adjusted to 38.0 Hz (–0.5 Hz, +0.0 Hz) on
the frequency meter.
