2.1 Power supply: one 9 V alkaline battery.
2.2 Current consumption: max – 85 mA.
2.3 At a load (see Fig.1) SCENAR performs:

generation of two-phase stimuli without a DC-component (see
Fig.2) with a waveform depending on the skin impedance under
the electrode (see Fig.3 through 5);
 control of the stimulus’ 1 st
phase duration (see Fig.2) within
(4 ± 2) to (500 ± 50) µsec, meanwhile the amplitude of the first
pulse of the stimulus’ 2
nd
phase at L1 load (see Fig.1) varies from
(1.7…2.8) V to (100…150) V. Amplitude control step – max 1 V.
