Impedance Variations
The Simulator replicates impedance variations of 0.2, 0.5,
1.0, 2.0, and 3.0 and 2000 delta Ohms. Use the LA/LL
switch on the top panel to select which lead will have the
respiration signal on it. This will not affect the baseline
operation.
The variation can be set through direct code entry, as
below, by keying the preset code and pressing ENTER.
You can also use the SCROLL keys
to cycle
through the other presets before pressing ENTER.
