Step 1:
Line up the DUT’s LED
with the PD of AECG100.
Step 2:
Confirm the position of the
DUT’s LED and AECG100’s PD
are lined up: Connect AECG100 to the computer and power
on AECG100. Download, install and execute the AECG100
software on the computer, and see if the pulse signals are
visible on the PD
’s
sampling tab. If so, the LED of the DUT is
lined up with AECG100’s PD.
Step 3:
Confirm the positions of the
DUT’s PD and AECG100’s LED:
Execute the AECG100 software, and under PPG test mode,
set DC=500mV AC=30mV BPM=60, and check if DUT can get
the heart rate of 60 BPM.
。
If so, then the relative positions
of DUT’s PD and
AECG100’s LED are correct.
。
If not, try to modify the DC value by adding or
reducing 50mV and check again to see if DUT can get
the heart rate of 60. If the heart rate is still not found,
