    The only time that these monitors can accurately read per- centages is when the total pressure does not vary over time between calibrations and use. For this reason it is important to calibrate the MX300-I Oxygen Monitor (with R17MED oxygen sensor) at regular intervals. It is recommended that the Monitor be calibrated prior to each use or every 8 hours, and at the same pressure the monitor normally operates after calibration.

    2.3.4 Discrepancy in Readings When a discrepancy in oxygen readings is detected, the Monitor’s readings should be verified by checking the MX300-I battery condition and calibration using 100% oxygen. If the Monitor can be calibrated, the unit is assumed to be in good working order.
