VII. OPERATING
INSTRUCTIONS
A.
Insert the FingerSim™ into the Holder
Carefully insert the short, flat, color coded end of the FingerSim™ into the slot provided at one end of the
FingerSim™ Holder. Grasp the sides of the color coded end and gently press the FingerSim™ into the Holder
until it reaches the stop of the holder (see Figure 10).
CAUTION:
Improper insertion of the FingerSim™ into the Holder can cause breakage. Insert the
FingerSim™ as shown in Figure 10.
CAUTION:
If the FingerSim™ is used without the recommended Holder, one must be very careful to
prevent movement between the sensor and the FingerSim™. Be sure no forces are applied to
the sensor or sensor cable (i.e. do not hold the sensor, or touch the sensor or cable) while
squeezing the color coded end of the FingerSim™ to generate the pulse signal. Motion
between the sensor and the FingerSim™ may cause erroneous SpO
2
and/or Pulse Rate
readings.
WARNING:
FingerSim™ are fragile and must be handled with care, they contain glass.

B.
Attach the Sensor
Attach the sensor under test to the FingerSim™ the same way you would to a patient’s finger. When testing a
finger clip sensor be certain the FingerSim™ is inserted all the way to the stop of the sensor. Position flex
sensors such that the emitter and detector are vertically aligned between ¼” and ½” from the tip of the
FingerSim™.
CONTRAINDICATION
: Do not use with reflectance or ear clip sensors. Use only with transmittance type,
finger or toe sensors.
Route the cable in such a way that it does not influence the sensor under test. For sensors with cables directed to the
back of the finger, route the cable through the Holder in the notches on the bottom (see Figure 11).
Some oximeter systems may generate readings during sensor attachment due to the relative motion between the
FingerSim™ and the sensor. Allow 30 seconds for stabilization before going on to the next step.
