Performing Pressure Calibration
Note: The following calibration procedure assumes that two cables and two pressure
transducers or probes will be used. When two pressure transducers are in use, three
pressures will be displayed: one for each probe and the difference between the two
pressures. The Console will support use of a single pressure probe. However, when
only one pressure probe is used, no differential pressure reading will be displayed.
Note: The pressure monitoring system has a functional range of (-) 150 mmHg to
(+) 900 mmHg with a display resolution of 1 mmHg. If one channel exceeds either
limit, the values displayed on the specific channel as well as the difference will be
invalid, which is indicated by either “
∨∨∨∨
” for values below -150 mmHg and “
∧∧∧∧
”
for values above 900 mmHg. If one channel is invalid, then the difference will be
displayed as dashes: “----“.
A. Assuming the pressure monitoring system has been activated and calibrated,
a measured value can range from (-)150 to (+)900 mmHg. If the System has been
activated or the Console is powered or rebooted, the sensors are no longer
considered to be calibrated. This is indicated with the three letters
CAL
instead of
the numbers. The probes may be calibrated/recalibrated at this time.
B. Select either
NEW
or
PREVIOUS
. By electing to use the previous calibration
constant (
PREVIOUS
), you are acknowledging that the last calibration value stored
was within acceptable limits. By selecting
NEW,
you are prompted to vent the
transducer to atmospheric pressure to establish the transducer offset point. By
pressing
CAL P1
and/or
CAL P2,
the specific channels are calibrated. Always
close the transducer vent before returning transducer into service.
C. The pressure monitoring system is now ready for use.
