    Product Code
    The Chauvin Arnoux CA6255 is a micro-ohmmeter (otherwise known as a “ductor” or “low ohmmeter”) with a really high accuracy as it has a resolution going down as low as 0.1μΩ. This makes it a great unit for use in checking the low-resistance quality of your connections and bonds.

    Advantages of the CA6255:

  • Optimized current generator on inductive objects
  • Measurement up to 2,500Ω, resolution 0.1μΩ
  • Automatic compensation of stray voltages
  • Calculation of R at a reference temperature – Pt100Ω probe
  • Automatic discharge after test
  • Programmable alarms
  • Storage of up to 1,500 measurements
  • PC communication

  • An easy-to-use, high-performance instrument, the CA6255 micro-ohmmeter tests the quality of connections with precision (resolution of 0.1 µΩ) through the use of low resistance measurements.

    4-wire measurement method, 1 µΩ to 2,500Ω (7x ranges, 3x with a 10A current) with automatic compensation of stray voltages at input terminals.

    Three measurement modes available depending on the application:

  • 1. Inductive – use on inductive components (transformers, motors, etc.)
  • 2. Non-inductive – for measuring resistors with a time constant of a few ms (contacts, metallization, etc.)
  • 3. Non-inductive with automatic trigger:
  • - for measurements on resistors without a time constant
  • - for repetitive measurements in production, saving considerable time

  • Other features include:

  • Temperature compensation function for comparative results
  • Programmable alarms
  • 1,500 measurement storage capacity
  • Large backlit LCD display with a wide range of symbols and indicators
  • 50 V CAT III rated
  • Power supply: NiMH rechargeable battery
  • Dimensions: 270 x 250 x 180 mm; weight: 4 kg

  • The CA6255 is suitable for measuring the following applications:

  • Chassis-earth continuity tests
  • Surface and metallization conditions
  • Quality of contacts (switches, relays)
  • Resistance of cables and windings
  • Heating of motors and transformers
