Some Lead without Waveform
Printout
If you acquire the ECG data
immediately after the leadwires are
applied to the patient, the ECG
traces may not display because the
ADS is not stable yet. Normally it is
necessary to wait for the waveform
of each lead to be stable if all leads
are in good contact before ECG
measurement.

AC Interference
Symptom: There is an overlap
of 50Hz sine wave with
certain amplitude and
regularity on the ECG traces,
and obvious jitter appears on
the ECG baseline.
Check the following aspects of the
device for solving problems:
 The device is properly
grounded.
 The electrodes and leadwires
are correctly connected.
 Enough conductive paste is
applied to the electrodes and
the patient's skin.
 Patient bed is properly
grounded.
 Patient not come into contact
with conducting objects such
as metal parts of the patient
bed.
