ATTENTION: Supply the SpO
2
simulator form a 12V source with the positive pole on
the cover and the negative pole on the pin, see the bottom of the apparatus!!!
The SpO
2
simulator has etalons available - “artificial fingers” with different nominal
values of SpO
2
. Try to attach the available etalons one by one to the simulator and place the
pulse oxymeter clips on them with a SpO
2
scanner. For each SpO
2
value of the etalon
gradually set all the pulse rate defaults on the simulator. Compare and record the selected
SpO
2
values and pulse frequencies with values on the pulse oxymeter. When attaching the
pulse oxymeter clips on the etalons, be patient and try to attach them as precisely as possible
to the beginning of the “artificial finger”. A demonstration of the SpO
2
simulator setting with
attached pulse oxymeter on the etalon is presented in Fig. 4.6.

Ad task 2)
Connect the analogue pulse oxymeter edutool (Fig. 4.7 on the left) via contact plugs to the
power supply +5 V and to the symmetrical power supply ±15 V. Attach the specialized probe
with a finger clip to the CAN 9 connector. Perform the edutool calibration; the switch being in
position 2 and the clip without inserted finger. The courses in the check points K11 and K12
should have the same amplitude (eventually adjust via variable resistors). If the output values
at both the channels remain different, their ratio gives us the correction constant. Use the
measurement probe on the oscilloscope to gradually display and compare the signals from the
check point of the analogue pulse oxymeter. The individual check points have the following
