C.4 Data Collection
C.4.1 Data collection procedure
Sampling Rate / Data Storage Capacity
A total number of 390 data blocks can be stored.
This number is independent of the amount of information that
is programmed to be on display and/or stored.
It is very important to determine a useful combination of the
measuring period and the data sampling rate.
If the flow rate shows only minor fluctuations or fluctuations
are not relevant a low sampling rate can be programmed.
Thus a long measuring period can be achieved or more than
one data collecting interval can be realized before the data
has to be transferred to a PC.
If the flow rate fluctuations are important the sampling rate
should not be too low. Otherwise, relevant information might
not be recorded.
NOTE: When all 390 data blocks are occupied no further data will be
stored. The flowmeter will continue to operate normally.
WARNING IS GIVEN WHEN THE DATA STORAGE IS FILLED
WITH 350 DATA BLOCKS (See chapter C.3.2. Error
Messages)
Reset Data
If a new measurement series is started (previous flow data
can be discarded) the data blocks can be cleared; two
RESET DATA functions are available:
1 use the function 3.6.6, RESET DATA, in the programming
mode
2 enter the QUIT/RESET menu (see section C.5.)from the
measuring mode and select the RESET DATA option.
Reset Totalizers
If applicable the totalizers must be reset at the beginning of a
measuring series. Enter the QUIT/RESET menu from the
measuring mode and select the totalizer(s) that have to be
reset (see section C.5)
