MONITORING
One (or more) of
the sensor
electrodes is not in
contact. The
relevant electrode
number will
appear instead of
the parentheses.
Press the center of the
electrode listed on the BIS
sensor to initiate contact
and enable monitoring.

UNABLE TO
MEASURE
ELECTRODES {0}
The system is
temporarily
unable to measure
data from one of
the electrodes on
the sensor. The
relevant electrode
number will
appear instead of
the parentheses.
If the issue does not correct
itself, replace the sensor.
LOW
POSSIBLE PIC
PROBLEM
Replace PIC or
check cable
using sensor
simulator
Ground electrode
impedance is high
and impedance of
other electrodes is
low.
Defective PIC.
1. Test another PIC with
sensor simulator.
2. If failure persists, replace
simulator and retest.
3. If failure persists, replace
PIC.
LOW
POSSIBLE PIC
PROBLEM
Replace PIC
One of the
electrodes (other
than ground) has
high impedance.
Defective PIC.
Defective sensor
simulator.
1. Test another PIC with
sensor simulator.
2. If failure persists, replace
simulator and retest.
3. If failure persists, replace
PIC.
