To change the width of the R Wave:
1. Push  or  to highlight the Width value.
2. Push .
3. Push  or  to adjust the width. Each push of a key increases or decreases
the width 20 ms for each key push when the value is 20 ms or above and
2 ms when the value is 20 ms or less. The Product simulates an R Wave
width of 8 ms to 200 ms.
4. When the amplitude is set, push  to enter the value and go back to the
R Wave Detection screen.
Set QRS Detection Test Values
The QRS Detection wave group supplies a signal that you can adjust the width of
the QT interval. This QRS Detection wave includes the R and S waves with
relative amplitudes as specified in EC-13. The R wave is 0.875 of the waveform
amplitude and the S wave is negative at 0.125 of the waveform amplitude. The R
wave up slope is 0.4375 of the waveform width. The R wave down slope is 0.5 of
the waveform width. The S wave up slope is 0.0625 of the waveform width.
To generate a signal for an QRS detection test:
1. Push  to show the ECG screen on the display.
2. Push  or  to highlight the Wave Group value.
3. Push .
4. Push  or  to highlight the QRS Detection value in the wave group list.
5. Push  to show the ECG: QRS Detection screen in Figure 10 on the
display.

You can change the rate, amplitude, and width of the QRS wave.
To change the rate:
1. Push  or  to highlight the Rate value.
2. Push .
3. Push  or  to highlight 30, 60, 90, 120, 200, or 250 bpm in the list.
4. Push  to set the rate and go back to the ECG: QRS Detection screen.
