B. Movement
Artifact
Analogous to the clinical environment, poorly attached sensors can result in movement between the oximeter
sensor and the FingerSim™ causing erroneous oximeter SpO
2
and Pulse Rate readings. Be sure to attach the
sensor to the FingerSim™ so that the emitting and detecting diode are vertically aligned and in direct contact
with the white transmissive surface about ¼” to ½” from the tip of the FingerSim™. Route the sensor cable in
such a way that it is not influencing the sensor attachment to the FingerSim™. For sensors with cables directed
to the back of the finger, route the cable through the notches in the bottom of the holder (see Figure 9).

Sensor Alignment and Position
The light absorption characteristics of the FingerSim™ are specified for light passing directly through the
FingerSim™. Be sure to vertically align the emitter and detector over the white transmissive surfaces about ¼”
to ½” from the tip of the FingerSim™. Misalignment or positioning on the black edges can cause erroneous
readings.
VI.
CHECK OUT
Before each use, visually inspect each FingerSim™ carefully. Do not use the FingerSim™ if the calibration date
marked on the color coded handle has elapsed. Do not use the FingerSim™ if it is cracked and/or leaking fluid.
CAUTION
: The SpO
2
simulation by the FingerSim™ is temperature dependent. See Charts 6, 7 and 8 for the
appropriate adjustment. Allow at least one hour stabilization at room temperature before using.
