Oxymitter 4000

c. Operation

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.
