1、SOFT_ADT_IR用红外进行活体检测性能上会比绿灯差，建议选择绿灯活体检测SOFT_ADT_Green。

参考配置见:HR_SPO2_NADT_ADT_V4300.ini(可联系代理商获取)

2、目前暂不建议调整活体检测的相关阈值，可以适当调整下ADT阈值即可。

Set Wear On/Off Threshold

Step1: If there are multiple IR LED or PD, please contact GOODIX RD to get device for best LED/PD selection

Step2: Find 5 subjects, for every subjects, wear the device on wrist (Including left hand and right hand) for 10

seconds, record average value for ADT raw data (subjects must be yellow skin people). The average value for the 5

subjects mask as A0L, A0R, A1L, A1R…A4L, A4R, average the above data and mark it as A.

Step3: Place the device to air for seconds, record average value for ADT raw data. The average value mask as B

Step4: WEARON_THRD = B + ((A – B) * 0.437 )

Step5: WEAROFF_THRD = B + ((A– B) * 0.437*0.9)

Step6: Set threshold parameters (At page ADT).
