Nerve Integrity Monitor
Stimulus Range: Stim 1 and Stim 2
0-3 mA, a minimum of ±12 V
compliance (tested into a 4K load)
Stim 1

compliance (tested into a 2K load)
Load Impedance Range: as long as the load impedance X
stimulation current is less than or equal to the compliance
voltage.

Stimulus Output Accuracy: ± .01mA (or ± 10% of reading at 1 K load) over Stimulus Range.
Stimulus Adjustment: Dedicated Side Control knobs and Graduated Touch Screen Control with display of
command current and delivered current.
Stimulus Measurement Accuracy: ± .02mA (or ± 10% of reading at 1 K load) over Stimulus Range.
Internal Fuse: 32mA Type F, 250 V 5 x 20mm (It must be Xomed #8253075, other similar
fuses may not give the same degree of protection). Order 8253075 Fuse Kit for
replacements.
