Chapter 4 Operation
While the cell fills with zero air, the Zero Purge screen indicates the time remaining.
Press ENTER to shortcut the purge.
CAUTION: The zero process requires five volumes of air (about 11 liters) to completely
flush the cell. Shortcutting this step will result in an incomplete purge and incorrect
readings during analysis due to an invalid baseline value.
The instrument automatically begins the zeroing process. Wait while the zero
measurement is taken. The screen displays the percent done. Use the up and down arrow
keys to toggle the measurement views.
