Parameters in the Measurement
Mode CA, CF and CK
Function
Average-Time
Standard Setting:
10
Setting Range: 1…20
The time (in seconds) for the generation of the
average value can be set with this parameter.
Filter-Upper-Limit-Offset
Standard Setting:
5
Setting Range: 1….20
With the setting of 20, this parameter
must be disabled for Mode CK !
Too high measurement values generated due to
metal wipers or blades are filtered out. The
offset value in % is added to the dynamically
calculated upper limit.
Filter-Lower-Limit
Standard Setting:
2
Setting Range: 1.….20
With the setting of 20, this parameter
must be disabled for Mode CK !
Too low measurement values generated due to
insufficient material at the probe head are
filtered out. The offset value in % is subtracted
from the dynamically calculated lower limit with
the negative sign.
Upper-Limit-Keep-Time
Standard Setting:
5
Setting Range: 1...100
With the setting of 100, this parameter
must be disabled for Mode CK !
The maximum duration (in seconds) of the filter
function for Upper-Limit-failures (too high
measurement values) can be set with this
parameter.
Lower-Limit-Keep-Time
Standard Setting:
30
Setting Range: 1...100
With the setting of 100, this parameter
must be disabled for Mode CK !
The maximum duration (in seconds) of the filter
function for Lower-Limit-failures (too low
measurement values) for longer-lasting
"material gaps", ie the time in which no material
is located on the probe, can be bridged.
Kalman Filter-Parameter in
Measurement Mode CK:
Q-Parameter
Standard Setting:
1x10
-5
Setting Range: 0.01…1
x10
-7
This Kalman filter parameter
Q
is used to
characterize the systemic measurement error. It
is recommended to leave this parameter to the
default setting!
R-Parameter
Standard Setting:
0.033
Setting Range: 0.01 ….. 0.1
This Kalman filter parameter
R
is used for
smoothing the measurement error. The lower
this parameter, the faster is the response to
smaller changes in the moisture readings. The
higher this parameter is the more smoothed the
measured value, but with a delayed reaction
time. It is recommended to leave this parameter
to the default setting!
K-Parameter
Standard Setting:
0.01
Setting Range: 0.01 ….. 0.2
This Kalman filter parameter
K
is used for a pre-
dynamic behaviour of the Kalman Filter for
higher changes in the moisture reading, i.e. the
reaction rate of the measurement signal can be
affected hereby. The K-parameter is related to
the Average-Time. It is recommended to leave
this parameter to the default setting!
