4. Validation
This allows the adjustment and validation of zero and detector sensitivity once
calibration is completed.

Operating mode
Detector selection
1. Select the detector to be calibrated with the help of the Previous detector
and Next detector keys and press Validate.
Zero calibration
1. The Zoom command is active.
2. Select the area of interest of the curve with the and keys. Press
Zoom + up to the activation of the Zero command. Adjust the position of
the cursor so as to make the “OK” appear, in turn indicating that the range
selected is sufficiently stable.
3. Press to select the term Zero.
4. Confirm the zero calibration by pressing Validate zero.
5. The term Sens (for sensitivity) is active from now on.
If sensitivity is not to be calibrated, press and END; until you see the
message “Do you only want to calibrate zero for the detector?”, then press
Validate calibration. Only the zero calibration of the detector will have
been carried out.
If sensitivity is to be calibrated, proceed directly to the following paragraph.
Sensitivity calibration
1. The Sens command is active.
2. Select the area of interest of the curve with the and keys. Press
Zoom + up to the activation of the command Sens. If applicable, adjust the
position of the cursor so as to make the “OK” appear, in turn indicating that
the range that has been selected is sufficiently stable.
3. Confirm the sensitivity calibration by pressing Validate Sens.
Record the calibration
1. The message “Do you want to validate zero and detector sensitivity?” is
displayed. Press Validate calibration to confirm the adjustment of zero
