OTQ Test Process (QR)
1. Check if the app scan method is QR.
2. Scan the OTQ with the in-app camera.
3. If the scan is successful, the measurement of the corresponding OTQ will begin.
4. Scanning one more time will end the measurement of the corresponding OTQ.
* The measurements can be accumulated by repeated scanning with the same OTQ.

OTQ-N Test Process (NFC)
1. Check if the app scan method is NFC.
2. If you are using the device for the first time, set the interval you want.
3. Touch the round scan button to tag NFC on the back of your phone.
4. If you scan it again, you can see the measurement history of the OTQ-N, and if you touch the upload button, you can finish the measurement of the OTQ-N.
* The measurements can be accumulated by repeated scanning with the same OTQ-N.
* You cannot change the interval set during the first use to the next measurement.
