Chauvin Arnoux Microhmmeter CA6255 

An easy-to-use, high-performance instrument, the C.A 6255 micro-ohmmeter tests the quality of connections with precision (resolution of 0.1 µΩ) through the use of low resistance measurements.

As part of their 125 year celebration Chauvin Arnoux have taken some of their more popular products and bundled them with free gifts. The CA6255 comes with a complimentary copy of their Dataview software, normally selling at $495.00 extra.

Typical Applications:

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

CA6255 Microhmmeter Comes Supplied With:

  • 1 set of cables 3 m long terminated by Kelvin clamps
  • 1 Euro mains power lead 2 m long
  • 9 user’s manuals (1 per language)
  • 9 simplified user’s manuals (1 per language)
  • MOT (Micro-Ohmmeter Transfer) data transfer software on CD-ROM
  • 1 x RS232 communication cable
  • FREE Dataview Software

Key Features:

  • Optimized current generator on inductive objects
  • Measurement up to 2,500 Ω, resolution 0.1 μΩ
  • Automatic compensation of stray voltages
  • Calculation of R at a reference temperature – Pt100 Ω probe
  • Automatic discharge after test
  • Programmable alarms
  • Large backlit LCD display offering a wide range of symbols and indicators.
  • Storage of up to 1,500 measurements
  • Communication with a PC
  • Large number of measurements:

VERIFICATION OF MECHANICAL CONNECTIONS

To make them easier to use and to permit new applications, new retractable 10 A KELVIN test probes are now available as accessories.

Temperature Compensation

The value of a resistance varies according to the temperature. For reliable supervision allowing the comparison of measurements which are comparable because they were made in the same conditions, it is a good idea always to express a measurement in terms of a given reference temperature. You can perform this calculation by simply pressing a key.

Programmable Alarms

Because an audio signal is sometimes all you need to interpret and assess a measurement, it is possible to activate a high and/or low alarm. If it is overshot, a buzzer sounds (adjustable volume).

Extended Measurement

The C.A 6255 is equipped with an internal memory capable of storing 1,500 measurements. They are memorized with two indices, OBJ (object) and TEST (test), which store the results in an ordered manner.
