Applications

The C.A 6292 is ideal for a wide range of sectors, including:

  • Electricity distribution,
  • Maintenance and repair firms
  • Railways,
  • Metallurgy,
  • Electrical equipment manufacturers (cut-off systems, circuit breakers, etc.).

It can be used for multiple applications:

  • Contact resistance testing on MV/HV cells
  • Verification of the quality of the contacts on the circuit breakers, switches, relays, etc.
  • Resistance testing on busbars, cables, windings, etc.
  • Continuity testing on rails, axles and welds
  • Checking of surface condition and bonding/metallization
  • Testing of cut-off devices

Ergonomics

The C.A 6292 micro-ohmmeter is a portable measuring instrument supplied in a rugged, waterproof site case. Its clearly-identified connection terminals limit the risk of errors and allow quick connection of the measurement leads.

The measurement results are displayed instantaneously on the backlit LCD screen for easy reading. The C.A 6292 can be configured directly using the rotary knob on the instrument or via a PC by means of the USB link.

Safety & reliability

The C.A 6292 allows measurement in total safety, for both people and equipment. In order to eliminate any risks due to inductive phenomena, the BSG method maintains earthing on both sides of the object measured.
