OPPO Watch 2 pressure measurement function:
The pressure measurement of OPPO Watch 2 is converted by calculating your heart rate variability (HRV), and the statistics of heart rate variability need to be measured by the PPG sensor of the watch, so when measuring the pressure, the green sensor on the back of the watch will be turned on.
Setting method:
After the watch is normally connected to the mobile phone, enter the watch menu interface in full intelligent mode, open the "stress" APP (smiley face icon), and follow the prompts on the page.
