7.3 Foam commissioning (with factory settings)
For use in applications with a signicant buildup of foam.
Performing foam calibration
1. Mount the sensor in accordance with the installation conditions, see “5 Mounting”.
2. Log in to expert mode, see “8.4.1 Expert mode”.

7. Fill with medium (without foam) until the probe is covered by at least 200 mm.
The maximum level must remain 200 mm from the process connection, howeve
8. Perform EXPRT-Foam-CalMed.
• !CalOk: Everything in working order, proceed to step 9.
• !faild: Carry out step 8 again.
