Polarization
NOR
For such polarization setting red plug is a
positive electrode, and black plug is a
negative electrode.
REV
For such polarization setting red plug is a
negative electrode and black plug is a
positive electrode. Warning means that such
a setting is the reverse of commonly
accepted way of marking polarity.
ALT
Automatic polarization switch in the half
performed treatment.

amplitude
-
0,3 – 140 mA in CC mode
Regulation step:
• 0,1 mA in the range of 0,3-10 mA
• 0,5 mA in the range of 10-140 mA
1,5 – 100 V in CV mode, max. 80 mA
Regulation step:
• 0,5 V in the range of 1,5-100 V
Remark: see Table 8.1.
Due to the limitations arising from IEC 60601-2-10, the value of the maximum amplitude depends on the pulse
duration. Permissible values are presented in the table.

Triangular pulse currents
Triangular pulse current consists of a sequence of saw-shaped pulses and independently adjusted times of pulse
and pause. It is used to stimulate denervated muscles (struck by flaccid paralysis) and smooth muscles. It is also
applied in electrodiagnostics to determine the I/t curve.
