3.13 Using the Nellcor Sensor Port
Inside every sensor manufactured by Nellcor (Tyco) is a unique resistor which is used by Nellcor-
technology oximeters in selecting a particular SpO
2
calibration curve (R-Curve) to match the oxygen
saturation characteristic of the sensor. The Nellcor Port located at the top of the
Oxitest Plus 7
enclosure (DB9 female) allows temporary connection of Nellcor sensors to the
Oxitest Plus 7
, so
that the sensor’s calibration resistor can be measured and the SpO
2
calibration curve corresponding
to the resistor selected. Use of the Nellcor Port thus facilitates high-accuracy testing of both
disposable and re-usable Nellcor sensors, with an accuracy of ±1 to 2% across the entire range of
simulated SpO
2
levels (35% to 100%).
At power-up reset, or when a Nellcor or Nellcor OEM pulse oximeter is selected from the
Oxitest
Plus 7
Pulse Ox menu, the default Nellcor "R-Curve" is selected. After selecting the Nellcor N-
200, for example, the Manual Mode display would appear as follows on the LCD:
N-200 NO SIGNAL
97% 60 BPM 100%
As long as the STATUS display remains in the
NO SIGNAL
state, the Nellcor port is sampled by
Oxitest Plus 7
.
To use the Nellcor Port, perform the following steps:
