The plastic tubing supplied with the gas should be pushed firmly
over the reducing connector.
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 if
the meter does not read 20ppm use the calibration tool to push the
calibration switch.
The unit will then beep 3 times, store the new calibration value, and
display the following:
The gas supply should then be turned off.
If the signal from the CO sensor is too low a new calibration value
will not be stored and the display will show:
The most likely cause for this is an expired cell but may also be
caused by depressing the calibration switch with no gas applied.
Ensure that the concentration of calibration gas is correct (20ppm),
that the connections to the gas cylinder are secure, and that the gas
cylinder is not empty, and then repeat the calibration procedure.
