Description

While measuring hysteresis time up or time down, the Closed loop system timed out. This indicates that the high or low flow rate can not be reached consistently.

Remedy

Retry the calibration. Check that the high flow rate can be reached consistently. If not, an increase in the tolerance band might be required.
