With automatic adjustment, the device selects the amplification so that the ECG
curve with the greatest amplitude overwrites 50% of the area available on the
screen. Consequently, individual, greater ECG swings can be displayed.
With manual adjustment, the amplification affecting the amplitude display can
be selected (x 0.25 / x 0.5 / x 1 / x 2).
The millivolt mark (in form of a rectangular impulse) is located at the left margin
of the curve field (mV-mark). Its height depends on the set amplification of the
ECG curve. The mV mark shows an amplitude height of 0.5 or 1 mV for
comparison, so that the amplitude of the ECG curve displayed can be
determined. The millivolt mark is also shown on the paper printout on the left
besides the ECG curve.
The selected amplification applies to all ECG curves displayed.
1. Select the ECG curve and open the curve context menu
2. Select the required amplification in the curve context menu and confirm.
The ECG curve will be displayed with the required amplification. Once the
selection has been made, the program leaves the curve context menu
automatically.
The sweep speed of the screen representation can be selected for the
configured ECG curves.
The following sweep speeds can be set:
• 12.5 mm/s
• 25 mm/s
• 50 mm/s
The selected sweep speed applies to all ECG curves displayed.
1. Select the ECG curve and open the curve context menu.
2. Select the required sweep speed in the curve context menu and confirm.
The program quits the curve context menu automatically and the ECG
curve is displayed with the required sweep speed.
The device adjusts the ECG filters automatically. The filters can be modified
manually if necessary for displaying the ECG curve.
The standard setting of the ECG filters in monitoring mode is 0.5 - 25 Hz.
The quality of the ECG depends among other factors on the ECG filter settings.
See chapter 7.4.4 Filter Settings (Persons Responsible for the Device), p. 165
for information on the filter settings.
See chapter 10 Procedure in Case of Malfunctions, page 233 for instructions on
improving the ECG quality.
