Caution:

You have to

·flow enough zero gas through the analyzer

·look for a stabilized signal

before starting the zero gas calibration.

Note:

You can go back to the menu "Basic Controls" with the F2 key.

Zero gas calibration is running

Note:

You can abort the procedure at any time with the F2 key.

Change to the main menu

Press

Alternative:

If you want to continue with the span gas calibration after the zeroing is done, you can go back to the basic controls with the F2 key or the -key.

(The spanning will be described in the next chapter: 4.2.2).
