acupoints F 3 button to enter measurement function, and analysis; if detected waveform characteristics cannot be effectively captured waveform observation, the re-change related settings, repeat these steps until test results were satisfactory.

Holds back the F3 key to enter the survey function, analyzes is measured the profile characteristic; If the capture profile cannot observe effectively, then changes the correlation establishment, duplicates above sequence of operation, is satisfied until the test result.

Pressing the F3 function key to enter the measurement, analysis of the measured waveform characteristics if capture waveforms cannot be effectively observed, you change settings again, repeat the steps above until satisfied with the test results.
