Calibration

1.
The need for calibration is based upon physical component changes that occur during use. The module requires
its first calibration after 1200 operating hours or one calendar year, whichever comes sooner, and then after each
4000 operating hours or once a year, whichever comes sooner. The message Calibration Due appears when the
hourly limit is reached. It is advisable to calibrate in the one-year maintenance program especially if the monitor is
used for intermittent, short term use typical of patient monitors.
