Red The lead is disconnected or not receiving a usable signal.
No color (unlit) No ECG data is being acquired.
Table 14: Hookup Advisor Lead Quality Status Indicators
Indicator Description
Red Shows a leadfail condition or extreme baseline shifts.
The red indicator is always the left circle of the indicator. It flashes on and off
approximately each second and contains an X mark. The two circles to the right
are black.
A message displays with information to help you resolve the problem.
Yellow Shows muscle artifact, power line interference, baseline wander, or electrode
noise.
The yellow indicator is always the middle circle of the indicator and contains a
dash. The left and right circles are black.
A message displays with information to help you resolve the problem.
Green Shows acceptable signal quality.
The green indicator is always the right circle of the indicator and contains a
checkmark. The two circles to the left are black.
A message displays showing that the signal lead quality is good to acquire an
ECG.
NOTE :
The background color of the Start ECG icon is green, when the Hookup Advisor
status is green. The background color of the Start ECG icon is blue, when the
Hookup Advisor status is red or yellow.
If a leadwire is disconnected, the overall status shows as failed (red). To determine
which leadwire has failed, you need to understand which electrodes are used to form
a lead. For example, if RA is the reference electrode and it is not connected, all the
electrodes display as failed.
If the Acquisition Module is disconnected during ECG acquisition, the
Hookup Advisor
does not display the lead status or messages and ECG acquisition is stopped. An
error message showing that the acquisition module is disconnected displays in the
waveform area of the Acquisition screen.
CAUTION :
ELECTRICAL INTERFERENCE - Electrostatic discharges may interfere with the
acquisition of ECG recordings. The acquisition module could be temporarily
disconnected with an error message displayed due to an ESD event. The device
