Calibration
Calibration will remain stable to within 2% over one month and
typically to within 10% over 6 months. CareFusion supplies calibration
gas (20ppm CO in air) and recommends that the unit is recalibrated on
a 6 monthly basis. See page 35 for calibration accessories.
To carry out the calibration locate the calibration switch on the right
hand side of the instrument as shown below.
Push the slide switch to the CO - PPM position and wait for the unit to
display zero.
