Message/Problem
Gas pressure failure
detected.
Verify that gas bottles
are securely tightened.
Calibration slope
error on: __________
Check sensors and
gas bottles for correct
placement and usage.
Press √ (OK) to
substitute default
calibration values.
Meaning and Corrective Action
This error message occurs if the calibrator gas pres-
sure drops off, indicating either a loose gas bottle or
a calibrator leak. Try tightening both gas bottles in
the calibrator. If the problem persists after retrying,
a calibrator failure error message will appear with a
specific code for leak failure. In this case, you will
need to contact your Terumo Technical Service repre-
sentative to arrange for repair. You have the option of
continuing use of the system without the calibration
process or trying another calibrator (if available).
The specific microsensors failing calibration slope
range appear in the blank. This includes one or more
of the following: arterial pH, PCO
pH, PCO , PO . This may be caused by incorrect

installation of gas bottles, damaged or mishandled
sensors, contaminated calibration solution, or poor
placement of sensors onto gas nozzles. Make sure a
Gas A calibration gas bottle is in the Gas A (orange)
port and a Gas B calibration bottle is in the Gas B
(blue) port. Check the sensor(s)/cable-head(s) for
correct sensor engagement and correct placement
in the calibrator. If you suspect the sensor has been
damaged or improperly handled, replace the sensor.
Retry calibration. If all of the above is checked and
the problem persists, even with fresh sensors, save
the failed sensor(s) and the printer failure report and
contact your Terumo Technical Service representa-
tive. You have the option of using the calibration
default values by pressing the √ (OK) key.
Note: If you press the √ (OK) key to substitute
default calibration values, then a message stating
"Calibration completed." will appear.
Note: If you are calibrating both arterial and ve-
nous BPMs and only one side fails, the passing side
will retain its new calibration data. If you decide to
continue use without replacing the failed sensor,
default calibration data will be applied to the failed
sensor (only). In this case, it is recommended that
you return to the configuration selection screen and
exclude the failed sensor/BPM from use.
