9 CALIBRATION
9.1 Calibration Specifications
9.1.1 Gas
Calibration span gas cylinders should have at least ± 5% accuracy and have a
current date stamp. Gas generators should have a current dated cell installed.
The type of gas mixture, how old the gas is and what temperature it has been
stored at will affect repeatability during field calibration.
IMPORTANT NOTES:
• Carbon dioxide sensors require 99.9% nitrogen (N
2
) for a true zero.
• If the cGas Detector has a splash guard you will need to flow the nitrogen
for approximately 4 minutes BEFORE you enter the Calibrate Zero menu.
