Gossen Metrawatt PROFiTEST MTECH (M520O) Features:

  • 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)

  • 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; Type B

Testing of RCCBs in IT systems

Special Features:

  • stands for direct incorporation of the Profitest Master into DDS-CAD planning software.
  • Display of approved fuse types for electrical systems
  • Energy meter start-up testing
  • Calculation of cable lengths for common copper wire cross-sections
  • Measurement of biasing, leakage and circulating current up to 1 A, as well as working current up to 150 A with the WZ12C current sensor clamp as an accessory
  • Phase sequence measurement (including highest line-to-line voltage)
  • 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
