[Filter] : ECG waveform filter mode. Options: Monitor, Diagnostic,
Surgery and ST.

[Monitor]: use under normal monitoring conditions.

[Diagnostic]: use when diagnostic quality ECG is required.

[Surgery]: use when the signal is distorted by high
frequency or low frequency interference. High frequency
interference usually results in large amplitude spikes
making the ECG signal look irregular. Low frequency
interference usually leads to drifting or rough baseline. The
surgery filter reduces artifacts and interference from
electro-surgical units. Under normal measurement
conditions, selecting this filter mode may suppress certain
features or details of the QRS complexes.

[ST]: recommended for ST monitoring.
[Gain] : ECG gain, to set the size of each ECG waveform.
The base gain is 10mm/mV.
Factor options: x 1/4, x 1/2, x 1, x 2and Auto.

[x 1/4]: make the height of 1mV ECG signal waveform
become 2.5mm.

[x 1/2]: make the height of 1mV ECG signal waveform
become 5mm.

[x 1]: make the height of 1mV ECG signal waveform
become 10mm.

[x 2]: make the height of 1mV ECG signal waveform
become 20mm.

[Auto]: let the monitor choose the optimal adjustment for all
the ECG waves. When ―Auto‖ is selected, the monitor will
automatically select one of the above six options and
update it timely.
[Notch Filter] : The notch filter removes the line frequency
interference. The notch filter can only be switched on or off when the
ECG filter mode is set to ―Diagnostic‖. In other filter modes, the notch
filter is always off.
Set notch filter frequency according to the power line frequency of
your country. To set notch filter frequency, follow the steps below:
1. Press [Main Menu]

press
[Enter].
2. Select the [Module] tab.
