E.2.1
Output and Calibration
The measurement output interval can be specified. Entries from 1 sec to 36000 sec are
possible. The factory default setting for the AQSync is 1 sec. Clicking on this value
brings up a keyboard that allows you to enter a different output interval, if desired.
Calibration values for slope and offset (in ppm) can be entered by clicking on the current
setting to bring up a keyboard. A calibration for CO
2
is carried out at the factory of the
CO
2
instrument manufacturer, and new values would only be needed if a new calibration
is carried out by the user or during factory servicing.
E.2.2
Zeroing
The CO
2
instrument’s zeroing frequency and the duration of the zero is pre-set in the
AQSync. The factory settings are for zeroing every 6 hours for a duration of 40 seconds.
Shorter times between zeroing and/or longer durations of zeroing would exhaust the
module’s soda-lime scrubber too quickly. See the
and in Appendix 1 for more information.
E.3
Ozone Module Settings
The ozone instrument in the AQSync is based on 2B Tech’s Model 108-L Ozone Monitor
and many of the features are the same. For more information about this measurement,
please consult the website for the Model 108-L:
https://twobtech.com/model-108-l.html
The Model 108-L user manual is linked on the webpage. Calibration values for slope
and offset (in ppb) can be entered using this screen (clicking on a number brings up a
keyboard). An ozone calibration is carried out at the factory for your AQSync, and new
values would only be needed if a new calibration is carried out by the user or during
factory servicing.
