screen for 3 seconds and then be replaced by the measured oxygen percentage value.
CALIBRATE
Press and hold this button for 5 seconds to start the calibration procedure.
CALIBRATION PROCEDURE
The calibration procedure can be run in two parts – a simple 21% recalibration or a 21–100 % span
calibration. To run a span calibration you must have a guaranteed source of 100 % oxygen, such as
from an oxygen bottle or hospital oxygen line.

5) Release the button
6) After a second or two the 21 % value will be shown on the screen. If the actual value is not
21 then perform a 21% calibration as above.
With all units, restoring the factory values and performing a 21% calibration will restore the unit to
+/-5 % accuracy. For full +/- 1 % accuracy, perform a full 21–100 % span calibration.

MAINTENANCE
Changing the battery
1) Whenthebatterylevelislow,thescreenwillashslowlyaboutonceevery2seconds.
 Iftheashingiscontinuousthenthebatteryisbelowtheminimumlevelandshouldbereplaced.
2) Undo the back cover of the device by undoing the securing screws in the corner of the backplate.
Remove the battery from the battery holder and replace with a long life, low drain 1.5 volt alkaline
battery. Replace the backplate and tighten all the corner securing screws.
Replacing the 22 mm Adaptor seal
1) There is an O-ring seal in the 22 mm Adaptor that prevents the leakage of gas from the
anaesthetic circuit. If this seal becomes damaged or is lost it must be replaced. Use a small
screwdriver to ease out the old seal and then press the new seal into place.
