 Bipolar mode in coagulation by pedal foot-switch or (with a particular selection) by automatic start/stop system, according to the conditions of the tissue
(impedance sensing); adjustable activation delay from 0.5sec to 5sec;
Typical working values: 0-30 = non activated system; less than 900 = start; from 1000 to 1700 = stop;
 Functioning memorisation system with 10 memories;
 Setting: by keys buttons for the functioning and the powers (indicated on the display in centesimal scale);
 Functioning control circuit: by twin microprocessor;
 Self-control and self-diagnosis circuit with delivery stop system, acoustic signal, visualization of the fault code;
 Neutral electrode safety circuit with acoustic signal (loud and intermittent), luminous signal (red), and visualization of the code;
 Protection against liquids: standard, non protected enclosure;
 Cooling system: by convection, without fan – Discontinuous functioning: max. 1 hour (10s ON/30s OFF);
 Shelf-life: 5 years;
 Dimensions and weight: (LxDxH) 38x35x17cm – 15Kg;
 Mains cable: 3m long, section 3x1mm

For broadcasting stations which use frequencies less than 800MHz, the distance can be established by using the equation: A: d = 4√P
For broadcasting stations which use frequencies between 800MHz and 2.5GHz, the distance can be established by using the equation:
B : d =2.3√P
P = Nominal power of the transmitter in watt (W), established by the manufacturer.
