Impedance Window Indications

1) Bar: Impedance between each electrode connected to human body and GND electrode is expressed as height. (Unit: k Ω)
2) Background color – green: Voltage accuracy during bioelectrical potential measurement is less than 0.1%.
3) Background color – purple: This means that the voltage accuracy is not guaranteed by 0.1% when measuring the bioelectrical potential.
4) The QEEG-64FX must have an impedance of less than 100k Ω for precise measurement of the vital potential voltage.
