IntroductIon
The AA01 CO2calibration accessory is designed for field calibration of any CO2sensor
produced by Veris Industries, regardless of age. It comes complete with calibration
gas, a gas regulator, tubing, and fittings, which can be configured to easily calibrate
your CO2device.
The calibration process normally takes about 5 minutes.
In general, Veris CO2sensors use a time-weighting factor, which saves the lowest
concentration of CO2measured in a selectable time period, and then use that
information to calculate the ambient or base level CO2concentration. This calculation
allows your Veris CO2sensor to improve its accuracy over time.
To use this instruction guide, first identify the shape of CO2sensor inside of your
Veris device (rectangular or pear), and then turn to the appropriate section of this
instruction manual for the specific instructions on how to calibrate your particular
device.
When connecting the gas regulator assembly to the gas bottle, verify there is at least
10 lbs of pressure remaining in the bottle.

NOTE: This product is factory calibrated. The typical CO2sensor calibration interval
is 5 years, depending on specific site installation factors. As of the date of this
document, compliance with ANSI/ASHRAE 62-2001 requires minimum on-site
accuracy verification intervals of 6 months or per the building operation and
maintenance manual. Accuracy verification should be performed using either a
comparison to a known reference or the CO2gas calibration kit available from Veris
Industries as model AA01.
WARNING: CO2sensor calibration requires a gas calibration kit. Performing calibration
without a gas kit will cause erroneous readings. Consult factory for calibration kit.
Select 0 ppm Cal Gas option.4.
Continue flowing gas through the sensor. Estimated calibration time is 5 minutes.5.
Unit returns to run mode when calibration is complete.
