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 CO
2
gas calibration kit available from Veris
Industries as model AA01.
