**********************
MODE
*EVENT
TIME
FLOW ANAL. 0-20 mA
**********************
EVENT-related sampling
By pressing the ENT key, the event-related sampling mode is
selected.
4.12.1
**********************
INTERVAL
00:10
**********************
Enter the sampling interval in minutes for sampling modes „TIME“
or „EVENT“.
A sample is e.g. extracted every 10 minutes.
(If you edit a time or event program, the next menu is „BOTTLE
FILLING“)

*FLOW ANAL. 0-20 mA
FLOW ANAL. 4-20 mA
**********************
FLOW ANALOGUE
By pressing the ENT key, the sampling mode „FLOW ANALOGUE“
(analogue signal 0/4 – 20 mA) is selected.
4.10.1
**********************
SAMPLES PER HOUR
AT 20 mA
40
**********************
If „ANALOGUE“ (0/4-20mA) has been selected, enter here how
often samples shall be extracted at a maximum analogue flow
signal.
Example:
- Flow analogue 0-20 mA
- At 20 mA 40 samples/hour shall be extracted.
- If there are on an average 10 mA for a period of 1 hour, 20
samples will be extracted.

**********************
MODE
FLOW ANAL. 0-20 mA
FLOW ANAL. 4-20 mA
*FLOW DIGITAL
**********************
FLOW DIGITAL
By pressing the ENT key, the sampling mode „FLOW DIGITAL“ is
chosen.
4.11.1
**********************
PULSE DIVIDER
25
**********************
Enter after how many input pulses (potential-free make contacts) a
sample shall be extracted in the sampling mode flow „DIGITAL“.
Example:
At a max. flow 1000 pluses/hour are delivered.
40 samples per hour shall be extracted. Thus the pulse divider
has to be set to 25.
5.2.2
**********************
BOTTLE FILLING
*TIME RELATED
SAMPLE RELATED
**********************
Select whether the bottle filling shall be time-dependent or whether
it shall depend on a pre-programmed number of samples.
