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. 
 4-wire measurement method, 1 µΩ to 2,500 Ω (7 ranges, 3 with a 10 A current)
 automatic compensation of stray voltages at input terminals
 3 measurement modes available depending on the application: inductive, non-inductive and non-inductive with automatic trigger
 temperature compensation function for comparative results
 programmable alarms / 1,500-measurement storage capacity
 large backlit LCD display offering a wide range of symbols and indicators
 50 V CAT III
 Power supply: NiMH rechargeable battery
 Dimensions: 270 x 250 x 180 mm; weight: 4 kg
