Calibration configuration
Calibration configuration
This option can be invoked directly from the main calibration menu by selecting the
Configuration
option, or by pressing the
Modify
button in either the zero calibration or high level adjustment screens.
The process sets all the parameters used for sensor calibration.
•
Auto-calibration
: This option is not available for the K1200 sensor.
•
Manual-calibration Auto-End
: On by default. When 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 (refer to
Configure manual calibration on page 60
for details).
If the calibration fails, the previous calibration parameters remain unchanged and a warning message
displayed.
•
Hold during calibration or verification
: On by default. 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 for a further 10
minutes to allow the system to stabilize.
•
Zero calibration bottle
: Ensure this is
disabled
by unchecking the box as it is not relevant for the
K1200 sensor.
If the
Stop parameters
button is pressed on the main configuration screen, 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 and not change them.
These values apply to manual calibrations with the
Auto-End
parameter set.
•
Start period
: is the minimum time period that must elapse before measurements are considered
valid.
•
Number of points
: is the minimum number of measurements that must be taken.
•
Stop criteria
: is the maximum allowable signal standard deviation value to ensure an accurate
calibration.
Configure manual calibration
This option sets the parameters required for manual sensor calibration.
•
Calibration mode:
•
Zero calibration
•
High level adjustment
•
In 100% humid air calibration (available for high range sensors only)
If zero calibration or
100% humid air calibration
is selected, no other parameters are required to
be set. However, the following parameters must be set if high level adjustment has been
selected.
•
Calibration sample
: 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.
•
Medium
: 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.
•
Gas unit type
: Either
partial
or
dissolved
are available for an in line sample. If gas bottle was
selected this is set to
fraction
.
•
Gas unit
: The list of available units depends on unit type selected above.
•
Liquid
: This defaults to
water
for K1200 sensors.
•
Reference value
: Enter the reference value for calibration
Press
OK
to return to the main calibration screen.
