Message/Problem
Chosen blood gas
module configuration
does not match
placement of cable-
heads in calibrator.
Verify proper placement.
Insufficient gas
pressure for Gas A (or
Gas B).
Replace bottle.
No gas flow through
sensor(s): A or B
Verify proper placement
of sensor(s) and cable-
head(s) in calibrator and
that vent cap(s) have
been loosened.
Meaning and Corrective Action
This occurs if the calibrator detects a different
number of cable-heads in the calibrator than what
was chosen during configuration selection. Check
the circles over the gas bottle level indicators in the
calibration screen. A green circle over the "A" and/or
"B" indicator signifies a fully engaged cable-head and
sensor in the associated calibrator pocket(s). A grey
circle indicates no engagement. Check to make sure
each cable-head and sensor is connected correctly
and captured securely in the calibrator pocket. Verify
the number of modules being used. If the error per-
sists, contact your Terumo Technical Service repre-
sentative to arrange for repair.
Note: If the monitor configuration chosen has only
one BPM while two are physically present, either one
will be accepted by the system and will not cause this
error message.
One or both of the gas bottles in the calibrator has
insufficient gas to complete the calibration process.
Replace the empty gas bottle(s).
The calibration gas is not flowing freely through the
sensor during calibration. The "A" or "B" designation
indicates which calibration pocket is affected. This
can be caused by closed venting caps, blocked gas
ports or blocked filter/sparger assemblies. Make
sure the large blue venting cap(s) on the top of the
sensor(s) are loosened and that the blue luer cap(s)
on the filter(s) are removed. Check to make sure the
sensor/cable-head(s) are securely captured in the
calibrator pocket(s). Check the calibrator gas port for
blockage. If there's any blockage, clean the port gen-
tly with a wet cotton-tipped swab. Press the √ (OK) to
retry. If the problem persists, replace the sensor(s)
and try again. You have the option of pressing the X
(Cancel) key to exit Calibration and continue use of
the system without completing calibration.
Caution
• If you suspect a blocked filter/sparger
assembly, it is recommended not to try to
remove it or clear it. This could result in a
loss of sensor chamber sterility.
