Descriere

Multifunction, digital measuring instrument for testing of earthing and lighting protection systems, PE conductor continuity testing and DC insulation resistance measurement on low voltage electrical installations in accordance with EN 61557.

 

MEASURING FUNCTIONS

  • Measurements on earthing and lightning protection systems include: standard 4-wire method, standard 4-wire method with current clamps and 2-clamp method without junctions disassembling.
  • Specific earth resistance (soil resistance).
  • DC insulation resistance measurement with test voltages from 50 V up to 1000 V in 10 V steps. Measuring range up to 30 GOhm.

 

OTHER FEATURES

  • mains voltage and frequency measurement
  • clamp current measurement
  • varistor testing.

Internal memory with a capability to store up to 1000 test results that can later be transferred to a personal computer.

 

SOFTWARE

Software package EarthLink compatible with Windows operation systems allows download of test results from the instrument to a personal computer.
