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 well suited 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.
  • 4-wire measuring method – no compensation of the measurement cables is required


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. Testing of electric charging stations per EN 61851-1 (DIN VDE 0122-1), for example general electrical installations with alternating or 3-phase current, public facilities, public authorities, universities, service providers in accordance with DGUV regulation 3 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+, EV and MI)
    • Testing of RCCBs in IT systems
    • Measurement of earth resistance (mains operation)
    • Standards-compliant testing of charging stations per IEC 61851 in combination with the PRO-TYP I/II test adapter
    • Automatic test sequence function
    • Bluetooth and USB interfaces
    • Push-print function – transmission of the measured value after measurement
  • Particularities

    Innovative, global operating concept

    • Quick access to measuring and test functions via the rotary switch and softkeys


    • No time-consuming replugging of the measurement cables is required

    Modern data management

    • Comprehensive data management concept in combination with user software including customer and measurement data administration, test sequences, report generation and more

    Unique storage concept

    • Creation of system structures – customers, systems, machines, distributors, RCDs, electrical circuits, earth electrodes, equipotential bonding rails, operating equipment and individual measuring points

    Push-print function

    • Transmission of the measured value via Bluetooth/USB after measurement has been completed

    Test sequences

    • Preparation of individual test sequences for quick and reliable testing of electric equipment

    Universal interface

    • Bidirectional data exchange (USB), connection of a barcode scanner, Bluetooth/USB: push-print function
