PRODUCT OVERVIEW
The AA01 CO2
calibration accessory is designed for field calibration of any CO2
sensor
produced by Veris Industries, regardless of age. It comes complete with calibration
gas, a gas regulator, tubing, and fittings. The calibration process normally takes
about 5 minutes.
In general, Veris CO2
sensors use a time-weighting factor, which retains the lowest
concentration of CO2
measured in a selectable time period. That information is then
used to calculate the ambient or base level CO2
concentration. This calculation allows
a CO2
sensor to improve its accuracy over time.
To use this instruction guide, first identify the shape of the CO2
sensor inside of your
Veris device (rectangular or pear), and then turn to the applicable section of this
instruction manual for the instructions.
Note: For all calibrations, when connecting the gas regulator assembly to the gas
bottle, verify there is at least 10 lbs of pressure remaining in the bottle. The CO2

sensor cannot be calibrated correctly with less than 10 lbs.
