2.4
Filter
The filter smoothes the flow measurement signal. Smoothing takes place in 8 steps and affects all out
puts. The switching times of the flow-related switching outputs and the rise and fall time of the ana
logue output change.
2.5
Security code
A 4-digit numerical code can be set to protect the device settings from unauthorized access. The secur
ity code must be entered each time the settings are changed in the EDIT mode and the TEACH mode.
2.6
Minimum/maximum value
In the SHOW mode, the minimum values and the maximum values for the flow measurement or the
temperature measurement are displayed and reset.
Switching off the operating voltage resets the minimum and maximum values.
