7.4.1.4.2 Zero calibration
With this method, the sensor should be removed from the sample and exposed to pure N
recommended to use the specially designed portable calibration device for this purpose.
Press Start to start the calibration.
A screen is displayed showing the measured values and length of time the sensor has been under
calibration. These values are continually refreshed.
The value % last calibration is an informational message showing the difference between the
current and previous sensor calibrations.
The Signal within range and Stability reached boxes indicate whether the calibration is within
acceptable limits. When both boxes indicate YES, press Finish to accept the new calibration. If one
or both boxes continue to show NO you can still perform a calibration but it is not recommended
and the calibration should be aborted by pressing the Cancel button.
Description
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
Select Zero calibration or High level adjustment. If using a high range
sensor you also 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.
