IMPORTANT:
Adjusting the calibration values impacts the displayed moisture readings. A change in the
moisture readings will have an impact on control. It is best to return the DM510 to manual control
before making adjustments to the sensor calibrations.
Inlet calibration bias (offset)
Outlet 1 calibration bias
(offset)
Outlet 2 calibration bias
(offset)
The displayed value is a bias or offset applied to the combined
temperature and dielectric signals returned from the DM510
moisture sensor. Adjusting this value has a direct impact on the
displayed moisture value on the
‘Main Operations Screen’
The
DM510 calibration procedure also has an impact on this and other
values when calibrations are performed.
Before adjusting this value cancel any calibration in progress and
note the displayed bias value.
Example Inlet calibration adjustment.
DM510 Inlet reading
=
26.5%
Manual test
=
21%
The DM510 needs to read 5.5% lower.
26.5 - 21 = 5.5
Reduce the
‘Inlet calibration bias (offset)’
value by
5.5
8
–
5.5 = 3.5
Outlet adjustments are similarly made. To increase the displayed
moisture reading the displayed bias value will need to be
increased by the required amount. To decrease the displayed
moisture reading the displayed bias value will need to be
decreased by the required amount. It should be noted that the
bias value could be a negative value.
