| Electrical Gear --- Stim-4 ---Technical Specifications |   |
Channels : Dual
Pulse Amplitude Adjustable 0-80 mA peak into 500 ohm load each channel. Constant current.
Pulse Rate (Adjustable) 2 Hz - 150 Hz
Pulse Width (Adjustable) 30 - 260
Modulation Mode Pulse width is automatically varied in a cyclic pattern over an interval of nominally 6.5 seconds. Pulse width decreases linearly over a period of .5 seconds from the control setting value to a value which is 60% less. The narrower pulse width will continue for 2 seconds, then increase linearly over a .5 second period to its original value. Pulse is maintained for 3.5 seconds, then the cycle is repeated.
Burst Mode Bursts consist of nine pulses at maximum pulse rate. Bursts occur twice every second.
Wave Form Asymmetrical Bi-Phasic square pulse.
Voltage 0- 34 Volt @ 500 ohm load
Max Charge per 20 micro coulombs pulse
Battery 9 volt battery (alkaline, or nickel - cadmium rechargeable.)
Battery life Approximately 50 hours at nominal range settings
Size 23.5x65x95mm
