Field CommentGain Sets the amplitude of the ECG signal. Measurement is in millimetersper millivolt and includes the following options:• 2.5 mm/mV• 5 mm/mV• 10 mm/mV• 20 mm/mV• 40 mm/mV• AutomaticThe larger the selected measurement, the larger the waveform. Onlythe representation of the waveform changes; signal strength is notaffected.NOTEIf Automatic is selected, the system calculates the bestgain based on the peak-to-peak amplitudes of all dis-played leads and the selected display format.Speed Changes the speed of rhythm printing and the wiper bar movementacross the display.Measurement is in millimeters per second (mm/s) and includes thefollowing options:• 5 mm/s (rhythm) / 12.5 mm/s (display)• 12.5 mm/s• 25 mm/s• 50 mm/sContinues on the next pageOperator Manual 12.2 Resting ECG Setup2053535-002 Revision T MAC 2000 ECG Analysis System 109/198
