Base line Filter
Base line drift is caused by a patient‟s breathing. ECG signal is overlapped on a large
parabola. If you want to set Base line drift, select „ON‟. Otherwise, select OFF. The set
value appears on the bottom part of the printed form indicating 0.1HZ- when set to ON,
and 0Hz- when set to OFF.


AC Filter
In addition to ECG, other signals such as power noise, base line drift by respiration and
electromyogram may be recorded in the output signals.
There are three types of the noise filter; 60Hz, 50Hz and OFF. When set to OFF, noise is not
eliminated. Set to 50Hz, it indicates to filter 50Hz power noise. Set to 60Hz, it means filtering
60Hz power noise.
When the system is powered by battery, power noise is not generated, so you may have
clear ECG signal if set to OFF. In Europe where the power noise is 50Hz, the system is set to
50Hz. In other nations including Korea and the U.S., it is set to 60Hz.
The status of the set filter can be checked on the bottom part of the printout, indicating
AC 60Hz, AC 50Hz or AC OFF.
