TECHNICAL DATA
CEFAR PRIMO is a nerve stimulator
(TENS) with two independent channels
and 9 pre-set treatment programs. The
stimulator has buttons for setting of
program and amplitude for each channel.
An automatic key lock is activated 20 sec.
after the amplitude has been set.
CEFAR PRIMO EASY is a nerve
stimulator (TENS) with two non-
independent channels and 3 pre-set
treatment programs. The stimulator has
buttons for setting of program, amplitude
and timer. An automatic key lock is
activated 20 sec. after the amplitude has
been set.
The stimulators run on either two non-
rechargeable 1.5 V AA batteries or two
rechargeable batteries, recharged in a
separate charger. Treatment with electrical
stimulation requires the stimulation
current to penetrate the resistance of the
skin and the electrode, about 1500 ohms.
CEFAR PRIMO and CEFAR PRIMO
EASY can penetrate this resistance and
maintain a current of up to 60 mA. With
a change in load from 100 to 1500 ohms,
the stimulation current changes less than
5% from the set value.
