Phase Auto Tuning - Advanced Sensors OIW-EX Series User Handbook Manual

2.3.4 – Phase Auto Tuning
Phase Auto Tuning is a process that automatically adjusts the frequency of the ultrasonic system to optimize
performance of the ultrasonic power supply.
optimal ultrasonic frequency will be identified in this stepwise tuning process.
When enabled Phase Auto Tuning will occur at the same point prior to the cleaning and homogenization phases in the
cycle but not for every cycle. Auto Tuning will commence in the following circumstances:

When auto tuning is first turned on (by an authorized AS Engineer);

When the measurement cycle is started;

The first Auto Tune Phase after 24:00 hrs;

With temperature changes of ± 5

When the user presses the SYSTEM TEST button.
Status Display during Auto Tuning Phase:
During this phase 'AUTO TUNING' will appear in the status display with a COUNT UP timer to indicate the time taken to
complete the auto tune sequence, rather than counting down the time.
The frequency tuning time will vary based on the frequency range to be swept and the size of the frequency steps taken
– therefore the tuning time is not configurable.
INFORMATION: A comprehensive software overview is covered in Section 3 of this manual.
