to turn off the AC filter.
——Select【DFT filter】: Select On/Off to turn on/off the baseline drift filter.
When the unstability of baseline is found, it is suggested to open the baseline
drift filter in order to eliminate the drift of baseline or the other interference
without any distortion of ECG wave, greatly enhance the ability of resist the
drift of baseline and also convenient for the interpretation of the waveform,
DFT will shown in the chart paper when the baseline drift filter is on, the
frequency of baseline drifter filter with the value of 0.05Hz will displayed
when the baseline drift filter is off.
——Select【EMG filter】: Cut-off frequency is optional. Options: 25Hz, 35Hz
or 45Hz.
——Select【Lowpass filter】: Cut-off frequency is optional. Options: 75Hz,
100Hz or 150Hz.
After setup of filter, select 【OK】.
Caution: The setups of EMG filter and lowpass are mutually exclusive, i.e.
only one setup is effective at the same time.
