MS-10 Diagnostic model current controlled Muscle stimulator with digital display of output current. Constant current is maintained independently of contact resistance.  Constant current pulses of Controllable amplitude and duration are precisely generated at .01, .03, .1, .3, 1, 3, 10, 30, 100, 300, 1000 ms at one pulse per second and is provided with a current meter giving direct indication of current even while treatment is being given, thus eliminating the need for switching the patient to meter circuit each time the current is to be estimated.  The unit can be used to plot intensity dur
