Calibration Unit
A reference gas cylinder inside the calibration unit is used to calibrate the sensor. Use
the Start/Stop key ( ) on the unit’s front panel to start or stop the flow of reference
gas. The gauge on the front panel shows the actual pressure in the gas cylinder.
Replace the cylinder when the pointer indicates LOW.
WARNING:
Gas cylinder contents are under pressure. Do not
puncture. Do not store or use near heat or an open
flame.
Never discard the container into fire or an incinerator.
Exposure to temperatures above 54°C (154°F) may
cause the contents to vent or the container to burst.
Remove the safety valve before discarding an empty
gas cylinder.
