An easy-to-use, high-performance instrument, the Chauvin C.A 6255 10A micro-ohmmeter tests the quality of connections with precision (resolution of 0.1 µΩ) through the use of low resistance measurements. Housed in a rugged construction-site type case with cover, the C.A 6250 is a self-contained instrument powered by a rechargeable battery with built-in charger.

It provides 7 measurement ranges, from 5 mΩ to 2,500 Ω, that can be accessed and selected directly on the front-panel rotary switch. It uses the 4-wire measurement method, with automatic compensation of spurious voltages.

This device is compliant with safety standard IEC 61010-2-030 and the leads are compliant with IEC 61010-031, for voltages up to 50 V with respect to earth in category III.

3 Measurement Modes

NON-INDUCTIVE MODE - for measurements on resistors with a time constant of a few ms (contacts, metallisation, etc.).
INDUCTIVE MODE - for measurements on inductive components (transformers, motors, etc.).
NON-INDUCTIVE MODE - with AUTOMATIC trigger: for measurements on resistors without a time constant: for repetitive measurements in production, helping to gain considerable time.

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.

FEATURES

Automatic detection of the presence of an external AC or DC voltage on the terminals
3 different measurement modes depending on the nature of the resistance to be measured,
Protection of the operator when a resistance having a large inductive component (motor, transformer, etc.) is measured.
Measurement up to 2,500 Ω, resolution 0.1 μΩ.
Programming of alarm thresholds.
Measurement temperature using a Pt100 jack on the front panel,
Function for automatic calculation of the resistance at a reference temperature
Extended memory making it possible to store approximately 1,500 measurements,
Indication of the level of memory use.
Indication of battery charge condition.
Automatic switching of the backlighting to standby to save battery power,
RS 232 interface to print the results on a serial printer or export them to a PC.
