ADJUSTMENT
6.3.3
One-point adjustment via the serial interface (command COXY1)
This adjustment calculates and sets a new gain or offset parameter value (depending on
the reference concentration used).
1
Enter the password,
see “Entering the password (PAS)”, page 37
2
The analog output can be held during an online adjustment with the command
ADJUST
ON
.
Input:
3
When adjustment conditions (gas pressure, humidity and CO
2
concentration) are
different from the operating conditions of the measuring device, set the ambient
parameters of the measuring device to the adjustment environment for the adjustment
duration. These settings must then be changed back to represent the process
conditions when the TRANSIC111LP is reinstalled in its operating environment. Further
information on setting the ambient parameters of the TRANSIC111LP can be found in
Section 5.
4
Enter command
COXY1
and confirm with the Enter button.
5
Connect the gas inlet and let the gas flow in.
6
The adjustment starts. The following commands are now available for selection:
–
Enter
- output the most current measuring result
–
R + Enter
– continuous output of measuring results. Press Enter to terminate output
mode.
–
Esc
– to terminate the calibration
7
Wait until the measured value has stabilized. Enter the span gas concentration and
press
Enter
. The new gain or offset parameter value is calculated and displayed.
The following is displayed after entering the command
COXY1
:
8
Now enter command
SAVE,
see “Save parameters (command SAVE)”, page 58
, and
press
Enter
. The new values are stored in EEPROM.
