Slowly turn the control knob anti-clockwise until the ball in the flow
indicator is between the two marks. This will then supply a gas flow
of approximately 0.25 l/min. Apply this flow for 25 seconds and then
use the calibration button tool to depress the calibration button.
The sounder will beep and the display will flash three times as the
calibration is recorded. The "GAS" legend will then be displayed.
Turn off the gas supply and the unit. When the cell has expired it will
be impossible to obtain a correct calibration and all the legends and
the three lights will flash five times with no beeps after the calibration
button is depressed. The "GAS" legend will be displayed as before
and the unit must be turned off before recalibration is attempted.
Important Notes:
 Only certified calibration gas (20 ppm) from a reputable source
should be used.
 Ensure that no CO is present on the sensor for 3 minutes before
starting the calibration procedure.
 Ensure that the instrument and gas cylinder have stabilized
at room temperature before calibrating.
 In order to stop any gas leak from the can after calibration,
ensure that the control knob is tightened firmly.
