Parameter labels display, but
without alarm status or data.
Parameter does not display label
or data.
Parameter does not display label
or data.
ECG Solutions
Problem
CHK LEADS message.
CHK LEADS message is
displayed with ECG waveform.
Displayed heart rate too low.
Displayed heart rate too high.
Possible Causes
AC power may not be
connected.
Sensor or cable is not connected
to monitor.
Parameter is "not available" in
power-up defaults.
Sensor or cable is not connected
to monitor.
Possible Causes
Electrodes may not be
conductive enough to provide
signal.
LEAD SEL softkey may be set
incorrectly (3-lead or 5-lead).
ECG patient leads and/or cable
are not connected.
Lead I, II, or III is being
monitored with 5-lead cable
installed and selected. One or
more leads not used for ECG
waveform is disconnected (e.g.
Lead II is being monitored and
LA is disconnected.
Insufficient R-wave amplitude.
Amplitude of ECG waveform is
too high.
10-1
Action/Solution
Verify AC ON light is on.
Connect appropriate sensor or
cable to monitor.
Contact service personnel to
change power-up status.
Connect appropriate sensor or
cable to monitor.
Action/Solution
Confirm electrode placement
and skin preparation and
adhesion.
Verify LEAD SEL is set for
correct lead configuration.
Confirm connections at lead
block and monitor.
Confirm electrode placement
and skin preparation. Confirm
leads are connected at lead
block. Make sure cable is
connected to monitor. If
possible, use 3-lead cable when
monitoring Leads I, II, or III.
Use ECG SIZE to increase
waveform size.
Select an ECG vector that
provides an R-wave amplitude at
least twice the T and P-wave.
Use ECG SIZE function to
decrease waveform size.
