Changing the Size of the ECG Wave
If any of the displayed ECG waves is too small or clipped, you can change the size of one or all of the
ECG waves on the screen.
Changing the adjustment factor only changes the visual appearance of the ECG wave on the screen. It
does not affect the ECG signal analyzed by the monitor.
Comparing the wave size to the 1 mV calibration bar on the ECG wave segment can help you to get an
idea of the true ECG signal strength. If you choose a fixed adjustment factor, the 1 mV calibration bar
will be the same size for all the displayed ECG waves. If you choose AutoSize, or an individual size
using the Size Up / Size Down keys, the calibration bar may be a different size for each wave.
