PPG Heart Rate Simulator Test System | User Manual
Usage in standalone mode
1.
Setting Mechanism
Optical measurement is quite sensitive against the distance and angle. Before HRS
unit is in use, please secure the particular distance and angle between HRS diffusion
film and DUT PPG sensor.
2.
Power Supply
HRS200 can be powered via USB interface or
Three AA batteries.
3.
Heart Rate Measurement
Please use BPM button to select and simulate
heart rate. In standalone mode, HRS200
provides 30, 60,70,80,90,120,150,180,210,240
BPM for selection. The default heart rate
value is 60 BPM.
4.
Preset Setting (Mode A/B/C)
In standalone mode, there are limitations of adjusting DC Level, PI value, and heart
rate. User can adjust those parameters via PC software and save up to 3 preset
settings (Mode A/B/C). User may directly choose preset setting via pressing the mode
button.
5.
Default Test Parameters
Characteristics of photodiode vary from one to another. This might cause certain DUT
being not able to use HRS 200 default test parameters. If this occurs, please use
HRS200/ PC software. In the main function page, user can adjust and find out
the ideal DC level and PI value. Aft
er that, user can click “Save to
HRS” button to save
as default parameters.

6.
Observe Analog Signals of Photodiode via HRS200 BNC Port
If user would like to observe DUT LED’s waveform, user can connect HRS200 to the
oscilloscope via HRS200’s PD BNC port. When connecting, user can directly
observe
HRS200’s hardware signals and i
t gives a higher accuracy compared with HRS software
or HRS SDK.

Default parameters for shipments are DC Level = 5, PI = 2.
