12. TECHNICAL DATA
CEFAR PRIMO PRO is a nerve stimulator (TENS) with two independent channels. It has seven preset pro-
grams and three custom programs. Programs and amplitude can be individually set for each channel.
Treatment with electrical stimulation requires the stimulation current to penetrate the resistance of the
skin and the electrode, about 1500 ohms. CEFAR PRIMO PRO 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 10% from the set value.
The stimulator operates on either two non-rechargeable 1.5 V AA batteries or two rechargeable 1.2 V AA
batteries, recharged in a separate charger.
