All electrical specifications are given for an impedance of 1500 ohms per channel (60mA) and for 1000
Ohms per channel for 99.5 mA.
outputs: Two independent and individually adjustable channels that are electrically isolated from each
other.
Pulse shape: Constant asymmetric rectangular current with pulse compensation for TENS programs
to eliminate any direct current component to prevent residual polarisation at skin level. Symmetric for
P10 NMES program.
Maximum pulse intensity: 99.5 mA in Constant Current mode or 99 V in Constant Voltage mode for
neurostimulation. 30 mA for electroacupuncture.
Pulse intensity increments: Manual adjustment of stimulation intensity from 0 to 99 mA in minimum
increments of 0.5 mA for Constant Current Mode, 0 to 99 V in 1 V increments for Constant Voltage
mode for electrostimualtion. 0,1 mA – 30mA steps 0,1 mA for electroacupuncture (5 V for first step).
Pulse width: 60 to 400 μs.
Frequency: 1-120 Hz
Maximum electrical charge per pulse: 80 micro coulombs (2 × 40 μC, compensated)
