4.4.1 Zero Cal

The Zero button on the front panel is used to enter the zero calibration
function. Zero calibration can be performed in either the automatic or manual
mode. In the automatic mode, an internal algorithm compares consecutive
readings from the sensor to determine when the output is within the accept-
able range for zero. In the manual mode, the operator determines when the
reading is within the acceptable range for zero. Make sure the zero gas is
connected to the instrument. If you get a

Press Zero to enter the zero function mode. The screen allows you to
select whether the zero calibration is to be performed automatically or manu-

settling. Stop when
Press Enter to begin zeroing.
The beginning zero level is shown in the upper left corner of the dis-
play. As the zero reading settles, the screen displays and updates information
on (unless the Slope starts within the acceptable zero range and does
not need to settle further).
Then, and whenever Slope is less than 0.08 for at least 3 minutes,
instead of Slope you will see a countdown:
These are five steps in the zeroing process that the system must complete,
AFTER settling, before it can go back to Analyze .
The zeroing process will automatically conclude when the output is
within the acceptable range for a good zero. Then the analyzer automatically
returns to the Analyze mode.
