IntroductIon
The AA01 CO
2
calibration accessory is designed for field calibration of any CO
2
sensor
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 CO
2
device.
The calibration process normally takes about 5 minutes.
In general, Veris CO
2
sensors use a time-weighting factor, which saves the lowest
concentration of CO
2
measured in a selectable time period, and then use that
information to calculate the ambient or base level CO
2
concentration. This calculation
allows your Veris CO
2
sensor to improve its accuracy over time.
To use this instruction guide, first identify the shape of CO
2
sensor 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.
