AECG100 | User Manual
For ECG, the data range is [-5, 5] mV.
For PPG, there are no limits for the range of the raw data, but you can
scale the range to [0, AC], which can be adjusted in AECG100 PC
software. If we set AC level for 10mV in AECG100 PC software, this
means the [0, AC] becomes [0,10]. Then AECG100 PC software will
automatically calculate the sample data value to a specific AC value by
the following formula:
[Data Value / (Maximum Data Value
–
Minimum Data Value)] *
Maximum AC Level
For example, if we setup AC level = 10mV while the maximum data
value is 12.500 and the minimum data value is 0.000, the sample data
0.021 will become [0.021/(12.500-0.000)]*10 = 0.0168 mV.
