Span gas ; Each sample gas having
concentration 90 to 100% of
its measuring range (recom-

externally and calibration is carried out
on the same calibration gas line:
Zero gas ; Dry air or atmospheric air
Span gas ; For other than O

• Indoor use (Select a place where the equipment does
not receive direct sunlight, draft/rain or radiation from hot
substances. If such a place cannot be found, a roof or
cover should be prepared for protection.)
• Avoid a place where unit receives heavy vibration
• Select a place where atmospheric air is clean
