  • Current measuring range: 0,1pA upto 1mA
  • Adjustable measuring voltage from 1V upto 500V
  • Manual or automatic range selection
  • Signalling limit by contact and beeper
  • Thermo-Voltage compensation
  • Automatic zero control
  • Adjustable timer from 10 upto 300 s
  • RS 232-interface incl. cables and PC-Software
