Description
Not available for this sensor.
When Auto-End is enabled a manual calibration will complete automatically when the
parameters defined in Stop parameters are reached. Press on Configure to set the
manual calibration parameters. If the calibration fails, the previous calibration
parameters remain unchanged and a warning message displayed.
If checked this keeps the last measured value and stops updating the outputs during
the calibration or verification process. This avoids sending invalid information to any
connected device. At the end of a calibration, this hold remains on for a further
10 minutes to allow the system to stabilize.
Make sure this is disabled by unchecking the box as it is not relevant for this sensor.
If this button is pressed you can view or change the existing values or restore the
default values. It is highly recommended to leave these parameters at their default
values. These values apply to manual calibrations with the Auto-End parameter
enabled.
Description
have the option of 100% humid air calibration.
Note: If zero calibration or 100% humid air calibration is selected, no other parameters
are required. The following are only required for high level adjustment.
Set to In line sample, Gas bottle or Factory parameters. If factory parameters is
selected, the Ksv value is displayed but can be changed.
These additional parameters are required if in line sample or gas bottle has been
selected as the calibration sample:
This is automatically set to Liquid if in line sample has been selected as the calibration
sample, or Gas if gas bottle has been selected.
Either Partial or Dissolved are available for an in line sample. If gas bottle was selected
this is set to Fraction.
The list of available units depends on unit type selected above.
Select Water for the for the K1100 sensor (default) or Beer for the M1100 sensor.
Enter the reference value for calibration.
