Description
PASS
Green An electrode PASSES the sensor check if
the impedance for that electrode is less
than 7.5 kiloohms. The ground
electrode (electrode 2 for a two-channel
sensor and electrode G for a four-
channel sensor) must be less than 30
kiloohms to pass.
HIGH
Red An electrode is labeled HIGH if its
impedance value is above 7.5 kiloohms
(30 kiloohms for the ground electrode).
If the sensor check displays this result
for a particular electrode, pushing the
electrode to create better contact
between the electrode and the patient’s
skin may help the electrode pass the
sensor check.
NOISE
Gray If the signal from the electrode goes
beyond the measurable range, NOISE
will be displayed. This notification may
appear if pressing sensor during check
or in the presence of large external
stimulus.
POOR
CONTACT
Red If the impedance check indicates that
the electrode is not in contact with the
patient, the sensor check will indicate
that that electrode is in POOR
CONTACT. If the sensor check displays
this result for a particular electrode,
pushing the electrode to create better
contact between the electrode and the
