The SPS 4000 works in conjunction with the Oxymitter 4000’s CALIBRATION RECOM- MENDED feature to perform an autocalibra- tion. This feature automatically performs a gasless calibration check every hour on the Oxymitter 4000. If a calibration is recom- mended and its contact output signal is set for “handshaking” with the sequencer, the Oxymitter 4000 sends a signal to the se- quencer. The sequencer automatically per- forms a calibration upon receiving the signal. Thus, no human interface is required for the automatic calibration to take place.
