7. LEAD (ECG)
A single action key which selects the ECG lead to be displayed. Each depression of the key
selects and displays the next ECG lead from the list. The list wraps around after the last entry
is selected. Choices are: I, II, III, aVR, aVL, aVF or V.
8. SIZE (ECG)
A single action key which selects the size of the displayed ECG waveform. Each press of the
key selects and displays the next ECG size which wraps around after the last size is selected.
A vertical bar is placed in front of the ECG waveform. This vertical bar is used as a reference
to determine the size of the displayed ECG waveform.
9. FREEZE (Screen)
A single action key which enables or releases the screen freeze function. The freeze key
stops or starts all waveforms, except when waveform 2 is used for cascaded ECG. When this
is the case, pressing the freeze key the first time causes the currently displayed ECG
waveform data to be transferred to waveform 2 and frozen. Waveforms 1 and 3 continue to
move. Pressing FREEZE again causes waveform 2 to return to cascaded ECG. The freeze key
is also used to enter the user configuration menu. See “User Configuration Mode” on
page 1-153 for further details.
10. ZERO 1 (IBP) (Optional)
A delayed action key which zeros the current pressure in the BP1 channel. If the transducer
zero process is unsuccessful, “UNABLE TO ZERO” is displayed in the IBP1 data window. This
window is only available when a pressure transducer is present.
11. ZERO 2 (IBP) (Optional)
A delayed action key which zeros the current pressure in the BP2 channel. If the transducer
zero process is unsuccessful, “UNABLE TO ZERO” is displayed in the IBP2 data window. This
window is only available when a pressure transducer is present.
