Safety Tester for electrical installations - PROFITEST Master Series

Test Instrument for VDE 0100 / IEC 60364.6
A broad-range measuring device allows for use of the test instrument in 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
Measurement of insulation resistance using nominal voltage, with variable or rising test voltage
Low-resistance measurement
Earth resistance measurement
Standing-surface insulation measurement
Universal connector system
Testing of residual current devices (RCCBs)

Measurement of contact voltage without tripping the RCCB.
Contact voltage is measured with reference to nominal residual current using 1/3 of the nominal residual current value.
Tripping test with nominal residual current, tripping time measurement

Special testing for systems and RCCBs

Testing of equipment and RCCBs with rising residual current including indication of tripping current and contact voltage at the moment the RCCB is tripped
Testing of RCCBs with: ½ × IΔN, 1× IΔN, 2× IΔN, 5× IΔN
Testing of RCCBs which are suitable for pulsating residual direct current; testing is conducted with positive or negative half-waves.
Testing of RCCBs with adjustable residual current for determining contact voltage

Testing for special RCDs

Selective S, SRCDs, PRCDs (Schukomat, Sidos and others), types G/R, AC, A and B
Testing of RCCBs in IT systems

Press releases

  • New METRISO G500 and METRISO G1000 Insulation Measuring Instruments

    METRISO G 500 and METRISO G 1000 insulation measuring instruments have been designed for master tradesmen, technicians and engineers from industry and the commercial trades in the areas of R&D, final inspection, type testing, routine testing, quality control and periodic testing.

    The instruments are compact and rugged, and are thus ideally suited for on-site use. They include features and functions which assure good legibility of test results at the backlit display, as well as excellent value for the money. They allow for convenient compensation of various measurement cable lengths during low-resistance measurement. Convenient two-hand operation is quick and practical - just suspend it from the neck strap and get straight to work.

    METRISOs can be checked by the user at any time for correct functioning - in accordance with VDE 0105-100 (EN 50110-1) thanks to the integrated 10 MOhm test resistor. The insulation measuring instruments can be used for measurements in accordance with the standards (EN 61557), as well as non-standard measurements (e.g. 1 mA varistor test in lightning arresters) and, at the same time, they're available as voltmeters for up to 500 or 1000 V.

    For even more operating convenience, an optional cable with remote triggering, a signal lamp and measuring point illumination are also available. The needs of those responsible for quality, auditing technicians and authorized inspectors have thus been met. A DKD calibration certificate is included as a standard feature.

  • PROFITEST PV - Peak Power Measuring Instrument and Characteristic Curve Tracer for Photovoltaic Systems

    With auto-ranging up to 1000 V / 20 A / 20 kW

    The PROFiTEST PV allows for the measurement of characteristic I-U curves, as well as individual photovoltaic modules and strings.

    With the help of a patented process, the instrument is capable of ascertaining peak power, internal series resistance and internal parallel resistance directly on-site “with only one measurement and without entering module data”, which are then indicated at a high resolution color graphic touch-screen which is suitable for use in sunlight.

    Troubleshooting in PV systems, as well as documentation of system quality, are executed quickly and economically during initial start-up and subsequent testing without a long learning curve.

    This simple yet decisive test assures safety for the customer and eliminates consequential costs for the installer.

    Measured peak power can, for example, also be used in order to determine peak ratio. Beyond this, acquired characteristic curves make it possible to draw further conclusions regarding the electrical characteristics of the measured module or string.
