*Important Calibration Information:
This instrument comes with a ‘manufacturer's certificate of conformity’. It is important to understand that this does NOT constitute a ‘traceable calibration certificate’. A certificate of conformity merely states that the equipment has been designed and produced to meet the requirements of its intended application.
Where calibration of an instrument is possible, we will offer this as a separately purchasable item and may be selected from the drop-down box above. You will be sent a full traceable calibration certificate produced in our laboratory and applied with your details as required.

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.

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

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 resistance varies according to the temperature. For reliable supervision allowing the comparison of measurements that 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 CA6255 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.
