53 KHz (± 3KHz)
Less than 500 mV AC
50-2000 ohms (one ohm resolution)
± 5%
(a) Internal 500 ohm Test Resistor
(b) Impedance in all Lesion Modes and in Stimulation
Mode when stimulation is off
(c) Audible Tone available where frequency varies
with impedance over full impedance range (50-
2000 ohms). Audible tone is adjustable and
mutable
(d) Warning on screen if impedance is less than 50
ohms or greater than 2000 ohms
Biphasic square wave with negative edge leading. This
wave is available in a variety of frequencies and widths.
