Instant Response Technology, an automatic adjustment, applies to the bipolar
mode, the cut modes, and the low 2 and low 3 coag settings. It does not apply to
the low 1, high 1, and high 2 coag settings. As tissue resistance increases, the
generator produces constant current followed by constant power followed by
constant voltage. The generator controls maximum output voltage to reduce
capacitive coupling and video interference, and to minimize sparking.
