Figure 69: Use Calibration Curve Interface
After adjusting parameters of RED or Infrared LED, R value and
SpO
2
level are changed simultaneously
. Press “Play” to have
AECG100 output optical signals.
(6)
Degree:
Change the degree of polynomial between linear and
quadratic when not using the SpO
2
table.
(7)
PI value:
PI refers to the Perfusion Index (PI). Fix AC value to
adjust DC and PI values, or fix DC value to adjust AC and PI
values.
(8)
Output DC
(Fine-Tune)
:
As ambient light and inner electrical
circuit offset of DUT would affect the DC value received by DUT,
users can fine-tune the Output DC to minimize the influence. The
default value is 0.
(9)
AC value:
To simulate the artery volume change of artery
diastolic phase and systolic phases.
(10)
DC value:
To simulate reflected optical signal of the average
artery and vein volume change from skin tissue, bone, and
muscle.
(11)
Parameter Lock and Adjustment:
Lock AC value to adjust PI and
DC value or lock DC value to adjust PI and AC value.
(12)
Table
(Upon clicking “
Use SpO
2
Table
”
): An SpO
2
level matching
table is built by entering AC and DC values of RED and Infrared
LEDs, along with the SpO
2
values resulted from DUT. These
parameters are used to adjust the intercept and slope of the linear
(Degree 1) or quadratic (Degree 2) equations.
