15OFFSET: This function helps set a non-zero offset to the zero calibration. It is useful when zeroing the analyzer with a background gas that is different than the sample.

16CAL-INDEPD: Not generally accessed buy the end user. Forces analyzer to be in independent calibration mode.

17STANDBY: Remove power to outputs and displays, but maintain power to internal circuitry.

Any function can be selected at any time. Just scroll through the MAIN MENU with the DOWN/UP keys to the appropriate function, and ENTER it. The analyzer will immediately start that function, unless password restrictions have been assigned. (Password assignment is explained further on.)

All of these functions are described in greater detail in the procedures starting in section 4.3. The VFD screen texts used to illustrate the procedures are reproduced in a Monospaced type style.
