C1 process input
C1.1
meter size
Select from size table.
Range: DN25...1000 mm / 1...40"
C1.2
calibration
C1.2.1
zero calibration
Display of current zero calibration value.
Query: calibrate zero?
Setting: cancel / automatic / default
Automatic (shows the current value as the new zero calibration value).
C1.2.2
GK
Select GK value (see nameplate of the measuring sensor).
Range: 0.5000...10.000
C1.3
filter
C1.3.1
limitation
Limitation of all flow values, before smoothing by time constant,
affects all outputs.
Range: -100.0….+100.0 m/s
C1.3.2
flow direction
Define polarity of flow direction.
Select: normal (according to the arrow on the measuring sensor) /
backwards (in the opposite direction to the arrow)
C1.3.3
time constant
Averages measurement
Increasing value improves stability but delays the reaction.
Master setting, overrules time constent settings of all outputs.
xxx.x s
Range: 0.0…100 s
C1.3.4
low flow cutoff
Sets output value of all outputs to zero. "0" appears in display.
x.xxx ± x.xxx m/s
Range: 0.0…10 m/s

C1.4
plausibility
Changes in values outside error limit are only accepted when number
of measurements exceeds counter limit (C1.4.3).
C1.4.1
error limit
Measurement is ignored if value exceeds the error limit.
One ignored value = counter +1.
Measurements within the error limit decrease the counter
(see C1.4.2).
Range: 0…100%
C1.4.2
counter decrease
Multiplier for every measurement within the error limit to decrease
the counter.
Range: 01…99
C1.4.3
counter limit
Above this value measurements will not be ignored.
Range: 000…999
C1.5
simulation
C1.5.1
volume flow
Query: sim. volume flow.
Select: cancel / set value (select value, start simulation? yes / no).
