Item No.: LM8565

Installation tester for testing protective circuity according to DIN VDE 0100, RCD type B

A wide-range measuring instrument makes it possible to use the testing device for all alternating current and three-phase supplies with voltages from 65 to 500V and frequencies from 15.4 bis 420Hz.

  • Loop and line impedance measurement
  • Measurement of the insulation resistance with the nominal voltage, or with a variable or rising test voltage
  • Low-resistance measurement
  • Earth resistance measurement
  • Location isolation measurement
  • Universal connection system
  • Display of approved circuit breaker types for electrical installations
  • Testing the start-up of energy consumption meters
  • Computation of line lengths for standard cross-sections of copper conductors
  • Measurement of bias, leakage and compensating currents up to 1 A as well as operating currents
  • Measurement of the rotating field direction (phase sequence, maximum phase-to-phase voltage)
  • Measurement of the contact voltage without tripping the circuit breaker
  • (In this case, the contact voltage relative to the nominal residual current is measured with 1/3 of the nominal residual current.)
  • Trip testing with nominal residual current, measurement of the tripping time 

Special testing of systems and/or RCD circuit breakers

  • Testing of systems or RCD circuit breakers using a rising residual current with a display of the trip current as well as the contact voltage at the instant of tripping.
  • Testing of RCD circuit breakers with: ½ × IΔN, 1× IΔN, 2× IΔN, 5× IΔN
  • Testing of RCD circuit breakers that are intended for pulsating DC residual currents; testing is performed with positive or negative half-waves
  • Testing of RCD circuit breakers with adjustable residual current in order to determine the contact voltage and the trip current (selective S, SRCDs, PRCDs, Schukomat, Sidos, type G/R, AC, A, A-EV, F, F-EV, B, B+, B-MI)
  • Testing of the alternating current and direct current tripping of universal current sensitive RCDs (type B)

Evaluation software

  • The software captures all the important data for reporting in accordance with DIN VDE 0100 Part 600
  • Test reports (ZVEH) can be generated automatically
  • Distribution structures with circuit/RCD data are individually definable
  • Created structures can be saved and loaded into the tester if necessary
  • The tester and the PC can exchange data bi-directionally via a USB connection
  • Data may be exported as EXCEL, CSV and XML
  • USB interfaces
  • Push-print function – transmission of measured value after successful measurement
