Problem
Possible Cause
Corrective Action
See
No waveform on
display. Trace
frozen &
communication
error.
Wrong com port
selected.
Select the correct com port in
PC-SAM setup menu.
2-3
3-6
No waveform on
display. Trace
frozen & no
communication
error.
No power to the ERT
Control/Gating Module
or communication
problem.
Check the power and serial
connections
2-1
2-2
Sweeping waveform
but no ECG signal.
No communication to
the ERT Module.
Check power to the ERT
Module & fiber optic cable
connections. Look for red light
in the fiber optic driver.
2-2
Sweeping waveform
but no ECG signal.
Lead off. Check lead attachment. 4-2
Sweeping waveform
but no ECG signal.
Offset voltage too large.
Check offset voltage in system
info window. Check for faulty
temp probe by disconnecting
the probe from the ERT
Module & check for needles in
muscle.
9-1
4-7
ECG waveform but
no heart rate
display.
R-detect parameters
incorrect.
Set correct values.
3-9
Excessive artifacts
on ECG without
scanning’
Movement of leads in
magnet bore.
Check for vibration or air flow.
Tape leads and/or ERT
module.
4-1
Excessive artifacts
on ECG while
scanning’
Movement of leads or
module in magnet bore.
Check for vibration. Tape leads
& ERT module to restrain
