INSTALLATION TESTER FOR PROTECTIVE CIRCUITRY ACCORDING TO DIN VDE0100, RCD TYPEB
The inclusion of a facility for wide-range measurement makes it possible to use this test meter for all AC and three-phase mains networks with voltages from 65 up to 500 V and frequencies from 15.4 to 420 Hz.
- 1 Tester
- 1 Earth contact plug unit (PRO-Schuko)
- 1 2-pin measurement adapter
- 1 Lead for enhancement to 3-pin adapter (PRO-A3-II)
- 2 Crocodile clips
- 1 Carry belt
- 1 Set of batteries (8 x LR6)
- 1 Brief instruction manual
- 1 Full instruction manual (on CD-ROM)
- 1 DKD calibration certificate

- Manufactured by Metrawatt: Profitest MTECH
- Measurement of loop and mains impedance
- Measurement of insulation resistance at nominal voltage, with variable or increasing test voltage for low-current measurements
- Measurement of earth resistance
- Measurement of in-situ insulation
- Universal connection system
- Display of authorised fuse/protection components for electrical installations
- Start test for energy consumption meters
- Calculation of line length for commonplace cross-sections of copper conductors
- Measurement of advance, leakage and compensating current up to 1 A as well as operating currents
- Measurement of direction of rotating field (phase sequence, maximum line voltage)
- Measurement of contact voltages with no tripping of switches.
(The contact voltage is measured relative to the nominal residual current and at 1/3 its value.) - Trip tests at nominal residual current/ measurement of tripping time
Special testing of installations or RCD circuit breakers
- Testing of installations and RCD circuit breakers via increasing residual current with display of tripping current and contact voltage at the moment of tripping.
- Testing of RCD circuit breakers at the following currents: ½ × IΔN, 1× IΔN, 2× IΔN, 5× IΔN
- Testing of RCD circuit breakers suitable for pulsating direct current. Testing can be done on positive or negative half-waves
- Testing of RCD circuit breakers with adjustable residual current to determine contact voltages and tripping current
- Testing of tripping by AC or DC with RCDs (type B) which respond to all current types
Evaluation software
- The software acquires all the key data for logging in accordance with DIN VDE 0100 Part 600
- Test logs (ZVEH-format) can be generated automatically
- Distribution structures including circuit and RCD data can be defined individually
- Structures defined in this way can be stored and loaded into the tester when needed
- Tester and PC can exchange data in either direction via a USB link
- Data can be exported in EXCEL, CSV and XML formats
