Calibration Menu Screen

Pressing the CALIBRATION key on the Service Menu Screen brings up
the Calibration Menu Screen. This menu allows the TSR to perform
calibration for the Oxygen Analyzer sensor and the Breathing Pressure
Monitor. Figure 2-5 shows a typical Calibration Menu Screen. The four-
digit numbers in the left column show the current values, while the
numbers in the right column show the values stored from the previous
calibration.
For a valid zero calibration of the Oxygen Analyzer sensor, the two
offset readings should be between 125 and 145, and the difference
between Cell A and Cell B should be no greater than 8. Pressing the
O2MED key stores the values, and the message OXYGEN OFFSET
READINGS STORED appears on the screen. Refer to Section 5 of this
manual for the complete calibration procedure.
For a valid calibration of the Breathing Pressure Monitor, the pressure
span reading at 60 cm H
the BAROMED key stores the value, and the message PRESSURE
SPAN READING STORED appears on the screen. Refer to Section 5 of
this manual for the complete calibration procedure.
