Each of these models unites before itself two instruments: instrument for measuring the insulation resistance and instrument for checking dielectric strength of isolation (insulation test at the point of the breakdown).

• For the safety of operator the possibility of remote control and control besides instrument with the aid of the panels (option 9613 and 9614)
• Measurement of insulation resistance with a test stress of up to 1 kV (DC 500 [v]/of 1000 c)
• Testing dielectric strength to 5 kV (ACE 2500 [v]/of 5000 c)
• Standard interfaces ([Vneshn]. entrance, output, external switch, RS-232C, GB-IB (option for 3153))
