6WHS Refer to the following table. Correct the possible cause identified by the INOP
message and verify that the INOP disappears.
Prompt: insert trans-
ducer in chamber
appears when the
transducer is in the
chamber and the cal-
ibration is started.
Microswitch in Calibra-
tion chamber is faulty.
Replace the Calibration chamber.
Calibration has
passed, but readings
fluctuate more than
2.0 mmHg (0.3kPa)/
30 seconds.
Membrane/electrolyte
worn out.
Re-membrane the transducer and restart
the calibration. If the values still fluctuate
more than 2.0 mmHg (0.3kPa)/30 sec-
onds, replace the transducer.

tc UN-PLUGGED
Parameter is ON and unplugged
from rack.
Perform Step 5 on page 5-3.
tc EQUIP MALF Malfunction in the transducer or the
module.
Refer to the related Task Window mes-
sages in Table 5-2 on page 5-4.
tc NO TRANSDUC No transducer is connected to the
module.
Connect transducer to module.
tc CHANGE SITE The site timer in the module has
expired.
Change application site and restart
timer.
tc CAL FAILED Calibration failed due to out of
range or unstable signal during cali-
bration.
For more information on the calibration
of the module, refer to tcpO2/tcpCO2
Module sectionof the 8VHU¶V5HIHUHQFH

tc CAL REQUIRD Calibration is required before apply-
ing the transducer to the patient.
Run a Calibration as described in
tcpO2/tcpCO2 Module sectionof the
8VHU¶V5HIHUHQFH0DQXDO
Note: if the message is still displayed
after calibration, run the calibration
again. If you get the same message
again, replace the module.
tc CAL RUNNING A calibration is running. Wait until calibration is finished.
tc STABILIZING The transducer has not yet reached
the selected temperature and/or the
skin is not ready to be measured.
Wait until measurement site has
warmed up and values become stable.
tc CHECK TIME Site timer due to expire in 15 min-
utes or less.
Change application site and restart
