In the menu "Zero/span calibration" you can set up and start the calibration of the analyzer. The procedure and the menus are the same as described for the analyzer module in chapter 5.1.1 (p. 5-5).

How to calibrate:

1)Select the measurement range:

·Press the ENTER key or the → -key in the line "Measurement range number" to enter the parameter. Select the range you want to calibrate with the − -key or the ↓ -key and confirm it with ENTER. The zero gas concentration and the span gas concentration of the range selected will appear in the corresponding lines, automatically.

2)Select the gas component:

·Go to the line "NO/NOx toggle!" with the ↓ -key and select the gas component you want with the ENTER key or the → -key. The component selected will appear in the line "Measurement gas", automatically.

3)Zeroing:

·Change to the submenu "Analyzer zero" with the F3 key (ZERO).

·Pay attention to the notes on the screen !

·Flow enough zero gas through the CLD.

·Wait for a stable signal (look at the headline of the display). Then, start the zero gas calibration with the F3 key (ZERO). The running procedure will be the same as it is described detailed in chapter 4.2.1 of the basic controls (p. 4-22pp).

·Go back to the menu "Zero/span calibration" with the F2 key or the ← -key after the zero gas calibration will be done (Messages on the display: READY/CAL OK).
