F2 Sweep Speed Changes the speed of the waveform on the display and
printout. Changing the measurement also changes the
speed of the wiper bar on the display.
Measurement is in millimeter per second (mm/s) and
includes the following options:
 25 mm/s
 50 mm/s
 12.5 mm/s - 5 mm/s
 12.5 mm/s
When the option includes two measurements (12.5
mm/s - 5 mm/s), the first speed is for the display and
the second speed is for the printout.
F3 Gain Changes the magnitude of the ECG signal on the
display or in the report. Measurement is in millimeter
per millivolt (mm/mV) and includes the following
options:
 5 mm/mV
 10 mm/mV
 20 mm/mV
 40 mm/mV
 2.5 mm/mV
 Automatic
The larger the selected measurement, the larger the
waveform appears. Only the appearance of the
waveform changes; signal strength is not affected.
NOTE
If Automatic is selected, the system calculates the
best gain based on the peak-to-peak amplitudes of
all displayed leads and the selected display
format.
F4 Low Pass Filter Toggles through the Low Pass Filter options: 20 Hz,
40 Hz, 100 Hz, and 150 Hz. It defaults to the setting
selected on the Stress Setup window. (See “Stress
ECG Settings” on page 9-13 for more information.)
If the ADS filter type was selected in Stress Setup, this
softkey appears regardless of whether the filter is on or
off. If the FRF filter type was selected in Stress Setup,
this softkey appears only if the filter is off.
F5 ECG Filter Type Toggles on and off the ECG filter type (ADS or FRF)
selected on the Stress Setup window. In addition, if the
FRF filter type was selected, toggling the filter off also
displays the Low Pass Filter softkey.
