When switched on the electrosurgical unit reports on the LCD display (PROGRAM section) the code of used deepware and
performs automatically a test to establish the correct operation of itself and of the connected accessories as well. In case
anomaly is found, a description of the error is visualized on the LCD display and in the same time an alphanumeric message is
shown coded according to the chart codes brought in the chapter MAINTENANCE. This test lasts about 10 seconds. At the
end of the control the equipment restores last use operational conditions, and activate the signal of alarm OC (open circuit).

The neutral electrode's circuit is continually watched by a special circuit (Skin Plate Electronic Control) that prevents danger of
burns to the patient due the loss of contact between the reference plate and the patient skin. The circuit is also watched to avoid
that the variation of the characteristics of conductibility of the plate can provoke reduction of conductibility of the circuit, and
therefore danger of burns to the patient.
The value of impedance found in the circuit of the neutral electrode is shown (by OC alarm lightening) to the operator that, if
he considers it suitable to the job to develop, he accepts it by pressing the OK push button (the written ‘YES’ appears on the
display). If the value of impedance is excessive its acceptance it is not acknowledged by the microcontroller of the equipment
(written ‘UP’ appears on the display), therefore the signal OC is not extinguished and the delivery of power has not allowed.
If the impedance value is accepted, the impedance indication is recognized and
the display and OC indicator are extinguished
.
If the shown impedance is accepted, but the impedance increases respect the accepted value, the unit avoid the delivery, shows
the OC condition, without acoustic signal (only present during delivery) and shows the new impedance value
.
The operator can
