Description
Opens the patient data entry window.
Changes the speed of the waveform on the display and printout.
Measurement is in millimeter per second (mm/s) and includes
the following options:
25 mm/s
l
50 mm/s
l
5 mm/s
l
12 mm/s
l
NOTE:
The ECG reports are printed at a speed of 25 mm/s or 50
mm/s only.
This changes the magnitude of the signal. Measurement is in
millimeter per millivolt (mm/mV) and includes the following
options:
2.5 mm/mV
l
5 mm/mV
l
10 mm/mV
l
20 mm/mV
l
10/5 mm/mV

For the 10/5 setting, limb leads appear at 10 mm/mV and
precordial leads appear at 5 mm/mV.
The larger the selected measurement, the larger the waveform
appears. Only the appearance of the waveform changes; signal
strength is not affected.
