Description
This parameter defines the beginning
of the display range.
This parameter defines the end of the
display range.
A
This parameter defines the channel for
differential pressure measurement at
the filter.
A
This parameter is used to define the
channel for volume flow measurement.
A
This parameter defines the approxim-
ate formula for the volume flow meas-
urement.
This parameter defines the limit value
for the clean filter.
This parameter defines the limit value
for the dirty filter.
This parameter can be used to set an
offset for the characteristic curve.
This parameter determines the upper
limit value for the volume flow.
This parameter determines the lower
limit value for the volume flow. The
measured value is 'frozen' when the
volume flow falls below the limit value.
