GENERAL INFORMATION
94121x rechargeable Nickel-metal hydride (NiMH) battery (4.8 V / ≥ 1200 mA/h).
Battery chargers: only battery chargers with the part number 6830xx can be used to recharge the batteries supplied with the
stimulator.
Product and accessories expected service life: 5 years
Electrode shelf life: refer to electrodes bag
NEUROSTIMULATION
All the electrical specications are supplied with an impedance from 500 to 1000 ohms per channel.
Channels: four independent and individually adjustable channels, electrically isolated from each other.
Impulsion form: constant rectangular current with pulse compensation to eliminate any direct current component to prevent
residual polarisation at skin level.
Maximum pulse intensity: 120 mA.
Pulse intensity increments: manual adjustment of stimulation intensity from 0 to 999 (energy) by minimum increments of 0.5 mA.
Pulse amplitude: from 60 to 400 μs.
Maximum electrical charge per pulse: 96 microcoulombs (2 x 48 μC, compensated).
Standard pulse ramp-up time: 3 μs (20 %-80 % of maximum current).
Pulse frequency: 1 to 150 Hz.
