„ GAIN Used to adjust the amplitudes of ECG waveforms for all leads.
Option:

2, AUTO
If GAIN is set to AUTO, the gain will be adjusted by the monitor
automatically. Each waveform is followed by a 1mV scaling line,
the height of which is proportional to the amplitude of the
waveform.
„ RHYTHM
Used to select the name of the rhythm lead. Option: I, II, III,
aVR, aVL, aVF, V1, V2, V3, V4, V5 and V6.
„ CATCH When the waveform is long enough, you can select this label to
freeze all waveforms except the rhythm lead waveform, and this
label changes to RELEASE; Press it again, the frozen waveforms
will be unfrozen, and this label becomes CATCH again.
When the waveforms are not long enough, if you select this label,
a dialog box will appear prompting that the analysis cannot be
done due to the inadequate data.
„ RECALL When the waveforms are frozen, you can select this label and
rotate the control knob clockwise or counterclockwise to review
the waveforms.
„ ANALYSIS When the waveforms are frozen, you can select this label to
perform the 12-lead analysis. During the analysis, the monitor
does not respond to any operation. At the end of the analysis, the
analysis result will be displayed on the screen.
