in section 5.3.3, Pre Bump Test, first.
1. To begin calibration, go to the menu, and select the sensor to be calibrate, then select
“ADAPTi al”. Refer to Section 5.3.4.1 for details of the Calibration Menu.
2. The operator will be asked to provide a background gas concentration. Use the arrow
keys to adjust the rightmost digit while pressing enter to commit each digit. Repeat this
for all digits.
a. It is recommended that prior to calibration to manually set the ventilation system
to reduce the background gas concentration to near zero.
b. It is recommended to use a trusted secondary measurement device (such as a
handheld gas meter) to obtain an accurate reading of the background gas
concentration. Enter this value for the background gas concentration when
prompted.
c. If background gas concentration cannot be reduced to near zero or if the
background gas concentration cannot be established, apply pure nitrogen gas to
the sensor prior and during the finding zero stage of calibration. Enter 0 for the
background gas concentration when prompted.
