Mode
It requires connecting the PPG-2R-940, PPG-2R-880 or PPG-2TF-660
module to initiate SpO
2
test mode. SpO
2
test mode can be separated into
2 sections. The upper section is for waveform selection and test parameter
setting; the lower section is for waveform playback display and setting.

BPM:
Adjust for different heart rates. The value is from 10 BPM
to 300 BPM.
(2)
R Value:
The R Value is the ratio of RED LED PI percentage and
Infrared LED PI percentage. Selecting PI (R) means changing the
SpO
2
value by altering the PI of the red LED; selecting PI (IR) means
changing the SpO
2
value by altering the PI of the infrared LED.

Level Equation Adjustment:
Default equation is
the Webster linear empirical calibration formula: SpO
2
level (%) =
110.0
–
25.0*R, where R is the R value from (2).
For known R curve, users simply adjust the SpO
2
value (by
indirectly changing the RED or Infrared parameters) to ensure the
DUT SpO
2
value changes along with that of AECG’s. Key
