* Remark 1:Heart rate test range is different in standalone mode and PC mode. In PC software mode, heart rate range is from 30 to 300BPM; in standalone mode, heart rate value can be set to 30,60,70,80,90,120,150,180,210,240BPM, plus user can manually select 3 of them as preset parameters.
* Remark 2:Lumen accuracy would be ±10Lux when the light source is lower than 400Lux.
* Remark 3:We suggest user to observe PD’s analog signals via connecting HRS200’s BNC port to the oscilloscope. Under High Resolution Mode, user requires to check “LED Off” option to switch off HRS’s LED and no optical signals will be sent then.
