Your advantages

  • Defined accessories for special measuring tasks
  • Intuitive user prompting with help function which provides support for pending measuring tasks
  • All decisive measuring functions can be quickly selected with the rotary switch.
  • Especially wellßsuited for mobile use, even at construction sites and in industrial environments, thanks to the compact, impact-resistant housing with integrated rubber protector
  • Also suitable for international use thanks to extensive setting options for language etc.


Testing of the effectiveness of protective measures at stationary electrical installations per IEC 60364-6 (DIN VDE 0100-600), EN 50110-1 (DIN VDE 0105-100) and other country-specific standards. For example, general electrical installations with alternating or 3-phase current, public facilities, public authorities, universities, service providers in accordance with DGUV A3 etc.
  • Technical characteristics
    • Defined accessories for special measuring tasks
    • Broad-range measuring device for all alternating and 3-phase electrical systems with voltages from 65 to 500 V and frequencies of 15.4 to 420 Hz
    • Loop and line impedance measurement with DC bias magnetization
    • Measurement of insulation resistance using nominal voltage, with variable or rising test voltage
    • Low-resistance measurement with automatic polarity reversal
    • Testing of residual current devices and special RCCBs (selective S, SRCDs, PRCDs, Schukomat, Sidos, types G/R, AC, A, F, B, B+ and EV)
    • Measurement of earth resistance (loop)
