Chauvin Arnoux CA6255 10A Micro-ohmmeter

The Chauvin Arnoux CA6255 10A Micro-ohmmeter can be used to investigate the quality of connections via taking low-resistance measurements.

In order to take low-resistance measurements, this instrument utilises a four-wire measurement method and features seven resistance ranges, three of which have a 10A current. The CA6255 Micro-ohmmeter has an overall measurement range of 1 µΩ to 2500 Ω with a resolution of 0.1 µΩ, ensuring that this instrument can be used for a wide variety of applications.

Furthermore, adding to this product’s accuracy and reliability is its automatic compensation of stray voltages and temperature compensation function (this function also enables the user to take comparative results). Moreover, the Chauvin Arnoux CA6255 10A Micro-ohmmeter includes three measurement modes which make taking measurements of various components simple and reliable. These modes are:

• Non-Inductive Mode: allows the user to take measurements on resistors with a time constant spanning milliseconds, for example, contacts, metallization
• Inductive Mode: optimised for taking measurements on inductive components such as transformers and motors.
• Non-Inductive Mode with Automatic Trigger: allows the user to take measurements on resistors without a time constant. This mode also facilitates repetitive measurements in production, improving the instrument’s (and therefore the user’s) efficiency.

These modes allow the user to tailor the micro-ohmmeter to his/her needs, whilst its multiple measurement tests ensure that this instrument can be used to obtain a comprehensive array of resistance readings.  The Chauvin Arnoux CA6255 10A Micro-ohmmeter can be used to:

• Perform chassis-earth continuity tests
• Test surface and metallization conditions
• Determine the quality of contacts (switches, relays)
• Measure the resistance of cables and windings
• Check the heating of motors and transformers
• Calculate resistance at a reference temperature (using the temperature compensation function and a PT 100Ω Probe – NOT included)

Each of the measurements obtained via these tests is displayed on the micro-ohmmeter’s large, backlit LCD display. Adding to this product’s convenience is its alarm function which allows the user to set upper and lower measurement parameters, the CA6255 will then issue an audible alarm if either of these values is breached.

Furthermore, its internal memory can be used to store up to 1500 measurements. The Chauvin Arnoux CA6255 10A Micro-ohmmeter stores these measurements in an ordered manner using two indices: OBJ (object) and TEST (test), ensuring that the user can easily interpret the recorded data.

This data can also be exported to a PC. The included MOT module of the DataView® software allows the user to recover and backup the measurement data recorded in the Chauvin Arnoux CA6255 10A Micro-ohmmeter.  This data can then be used to create reports or may be exported into an Excel document and/or pdf file. Finally, the MOT module of the DataView® software can be used to manage databases and configure the Chauvin Arnoux CA6255 10A Micro-ohmmeter.

This combination of measurement functions, features and modes, as well as its easy-to-use design makes the Chauvin Arnoux CA6255 10A Micro-ohmmeter suitable for a variety of applications, from measuring the resistance of cables to checking the heating of motors and transformers.
