How do you check impedance?

Zeto headset uses active electrode technology; that is, it amplifies and boosts the signal right above the electrode. Therefore, our system can handle impedances above 100 mOhm. Our real-time signal quality indicator presents a continuous picture of the electrode contact with the skin plus external interference that may affect a particular electrode, which gives a more complete picture than just electrode impedance at the start of the recording. A prominent color change allows users to decide if they wish to intervene or wait for signals to calm down.
