On / Off - The Myogram filter reduces muscle induced noise. The use of the Myogram
filter can reduce the signal amplitudes by 20%. Average cycles and measurements
are not affected by this filter. The setting here defines if the filter is applied by default
or not applied.
On / Off - The baseline filter (SBS Baseline stabilizer) greatly reduces the baseline
fluctuations without affecting the ECG signal. The purpose of the this filter is to keep
the ECG-signals on the baseline of the printout and screen. The setting here defines
if the filter is applied by default or not applied.
50 Hz / 60Hz - The mains filter is an interference filter that suppresses AC interference
without distorting the ECG. Select between OFF (not recommended), 50 Hz, or 60 Hz,
according to your local mains supply frequency. 50 Hz for international ; domestic
should be 60 Hz unless other Operator/user instructions provide for changing the HZ
on the device.
The filters are switched On or Off during a recording with the Filter key icon at the top
of the screen. When the filters are switched on, the filter icon is highlighted.
The default setting (on or off) when the acquisition screens are entered is defined in
the ECG settings (see page 59).
