5.3.3 Standstill criterion
The condition for a standstill indication can be set by means of the parameter
”StiLL” in the menu
Func . The parameter values 00 to 29 are permitted in
accordance with the following table
(First digit = time interval, second digit = step width).
Standstill is indicated when the measured value varies maximally by the pre-
set step width within the time interval.
Parameter values (00...29):
Time interval for standstill testing
1 second 0,5 seconds 0,2 seconds
max. step width
any 00 10 20
1 d 01 11 21
2 d 02 12 22
3 d 03 13 23
4 d 04 14 24
5 d 05 15 25
6 d 06 16 26
7 d 07 17 27
8 d 08 18 28
9 d 09 19 29
•
For specific filter settings (large ”Icr”−values), the time interval cannot be
smaller than the response time of the filter. This taken into acount automati-
cally, the parameter ”StiLL” will then indicate only the minimum time period
for the standstill criterion.
•
The settings 0, 10 and 20 have the effect that no standstill testing takes
place. Processes that depend on a standstill (taring, printing, summing) are
always executed.
•
With an activated special filter (setting ”F_FiL” = 8 or asf8−command), the
time interval has been significantly extended when compared to the filter
settings 0..7, it depends on the parameter ”Icr”. Using the value of ”StiLL”
only the step width can then be set (e.g. the settings 04, 14 and 24 are of
equal value). The standstill test is always active, the settings ”StiLL” = 00,
10, or 20 are treated as ”StiLL” = 01.
•
The user must set a value in accordance with the calibration regulations.
