Span values can be changed if using different gas cylinders than those listed. Changes can be made using
MSA Link software and through calibration cylinder setup.
*For most accurate results, calibration with ClO
**Zero cal time is one minute if a catalytic combustible sensor is installed - 30 seconds if not.
LEL values, if not listed here, are according to EN 60079-20-1. Local regulations may
differ.
