2 FLOWRATE
2.6 CUT-OFF
Determines a minimum threshold for the required flow. If during this time
less than XXX pulses are generated as set in 2.5: FLOWRATE >
CALCULATION, the flowrate will be displayed as zero.
The cut-off time has to be entered in seconds. The maximum time is
999.9 seconds (approximately 15 minutes).
2.7 FILTER
Stabilizes the flowrate reading. This digital filter setting produces a more
stable but less actual reading. The filter principal is based on three input
values: the filter level (01-99), the last calculated flowrate, and the last
average value.
The higher the filter level, the longer the response time of a changed
value. Use trial and error to find the best setting for your application.

3.3 LCD NEW
Calculating the display information significantly affects the power
consumption. When the application does not require a fast display
refresh rate, it is strongly advised to select a slow refresh rate.
Information will not be lost, every pulse will be counted, and the output
signals will be generated in the normal way. The following can be
selected:
fast, 1 sec, 3 secs, 15 secs, 30 secs, off
When “off” is selected, the display switches off automatically. When an
update rate other than “fast” is selected, pressing a key will switch the
update rate to “fast” for 30 seconds. After this time, the display will return
to the configured update rate (or switch off).
Save battery lifetime by choosing an update time of 1 second or longer.
After the operator has pressed a button, the display refresh rate will
always switch to fast for 30 seconds. When 'OFF' is selected, the display
will: temporarily turn on after one of the keys is touched; and
automatically turn off after 30 seconds.
