The E13-22 is a basic, two-pole, resistively regulated, battery powered aversive electric stimulator, designed for finger stimulation. The unit features series resistance-regulation.
Series resistance-regulated stimulators can never deliver more current than the total circuit resistance predicates. The set accuracy is controlled by use of a fixed series resistor. The regulation is +/- 10% over a 10K to 30K subject resistance change and is designed for long session use. Being battery operated, it is fully isolated for subject and operator safety. The remote operate control input is optically isolated to simplify operation from any signal source from 5 to 30 VDC and to preserve total isolation. The output stimulus configuration consists of a series of low current pulses the frequency of which is set to 50 pulses per second.
