… Limas23 – Replacing the UV lamp (EDL)
4. In the menu tree, click on ‘Limas23 UV Detector 1’ and double-
click on the ‘Limas23 Configuration Parameters’ in the
‘Detector’ window in the ‘Correction Functions’ tab.

5. Enter the serial number of the new lamp in the ‘Limas23
Configuration Parameters’ dialog (without using the three
leading digits ‘111’) and close the dialog by clicking on ‘OK’).

6. In the ‘File’ menu, click the ‘Send module data’ command and
send the changed data record to the gas analyzer.
Adjusting the zero point of the electronic SO

cross-
sensitivity correction
An electronic SO
2
cross-sensitivity correction can be configured
in a gas analyzer that only measures the sample component NO
(‘Limas cross-sensitivity correction’ is activated in the ‘Detector’
window under ‘Correction functions’).
In this case, SO cross-sensitivity correction must be adjusted
before

the intensity normalization:
1. Wait for the gas analyzer to warm-up.
2. Feed in zero gas and wait until the display of measured value
is stable.
3. Click on Optima TCT Light the ‘Calibration’ command in the
‘Overview’ menu.
4. In the ‘Calibration – Overview’ window, click on the ‘Limas
cross-sensitivity zero gas’ function.

5. Select the detector and start the calibration by clicking
the
icon. Perform the calibration step by step.
6. Then carry out the intensity standardization for the
measured component NO.
