EDO 4 ENABLES TO CARRY OUT TESTS FOR:  -Dielectric strength;  -Continuity of the   equipotential circuit;  -Insulation resistance;  -Residual voltage in    accordance with the directions of the IEC  roduct rules and with the EC directives.

EN 60439-1 (CEI 17-13/1) 
Concerning electric boards, type AS and ANS. 

CEI 23-51 
Concerning electric boards for domestic use and similar. 

EN 60204-1 (CEI 44-5) 
Concerning appliances electric equipment 
 

EDO  4  is totally  microprocessor  run,  thus  enabling  to  get  all   the measures  in true effective value (TRUE RMS). Every command to be given to EDO4, except for high voltage regulation during the dielectric strength test, goes through the 8 buttons of the front switchboard only. 
With      EDO4     microprocessor    it    is    possible   to   switch  scale automatically   (if  provided  for),     to    support     the     precision     of measurements with a software and to set measurements either with a software or with a hardware. 
EDO4  can  also  store  2000 tests already done. It is possible to print stored  results  by  linking  a  parallel  printer  to  the connector already present  on the appliance, even after it has been switched off. Remote control  allows  EDO4  programming  through  PLC or  by any external keyboard.  EDO4   allows  a  PC  to  be  linked  through  a serial gate 
RS232. The employed display is of an alphanumeric kind, backlighted with 4 lines and 40 columns. The following table shows all the feasible parameters to input and the precision of measurements.
