selection. If a sensor address in brackets (n) is selected, no measure-
ment is initiated. Measuring channels without sensor can thus be
preconfigured.
Activate sensor?
The sensor can be deactivated if a malfunction occurs. The settings
remain stored.
Offset:
The fraction value of the sensors in the air is trimmed to 100 units and
allows the sensors to be replaced without having to recalibrate. The
sensor must be dry and may not come into contact with any material
(only air). The fraction value of the sensor is then read off in the test
screen. The difference to 100 yields the offset.
Example:
Offset = 0 testscreen shows 112,
Offset = -12 testscreen shows 100
Batching cross-section:
Allows weighted mean value calculation, as well as a curve switching
with fine batching.
Measuring range:
Range for the issue of measured values and display in whole percent
units!
Lower
threshold
/
upper
threshold:
The thresholds concern the working range of the mean value calcula-
tor. A stray value or an interruption in the material flow is therefore not
included in the mean value. In the „..MW continuous“ measuring mode,
this halt function can be deactivated as required. „hold“ will then not be
reset.
Delay time:
The mean value calculation is initiated when the measured value is
within the thresholds and a delay time has elapsed. The material flow
may undergo „transient oscillation“ during the delay time. The duration
of the required delay time can be established via "take sample".
Continuous time:
Memory of the continuous mean value calculation. A larger value ef-
fects a stabilisation of the measuring value, however also a signal de-
lay in the measuring modes „..MW continuous“. Set the value as low as
possible!
Hold:
This parameter is the default and may not be changed without consult-
ing ACO.
