A filter sets the upper frequency limit for the ECG waveform displayed on the
Filter
Acquisition screen and the printout. Selecting a filter eliminates signals that exceed
that frequency. The smaller the filter selected, the more signal is filtered out. For
example, a filter of 40 Hz displays only signals less than 40 Hz; signals greater than 40
Hz are ignored.
Gain indicates how many mm represent 1 mV of waveform data on the screen and
Gain
printout. You can change the gain to modify the display or printout of the waveform
to your preference. Changing the gain changes the amplitude of the waveforms. A
higher gain makes the amplitude of the waveform appear higher; a lower gain makes
the amplitude of the waveform appear lower.
The 10/5 mm/mV setting is used to display the limb leads (I, II, III, aVr, aVI, and aVf) at
10mm/mV and chest leads (V1 to V6) at 5 mm/mV. This is done to reduce or prevent
waveform overlap in the chest leads, while avoiding tiny waveforms in the limb leads.

Speed indicates the speed the ECG waveform displays on the screen and rhythm
Speed
printout. You can change the speed to render the waveform slower or faster to aid
in viewing or analysis of the waveform. A faster speed makes the waveform display
more stretched out; a slower speed makes the waveform display closer together.
