■THE OUTLINE■

AX-1155B is available to measure the super-low resistance with high speed and high accuracy from 0.00mΩ to 15.000Ω(% measurement : 1mΩ〜10kΩ) In addiition, it is possible tom make the measurement the measuring object accumulately and stable, because they have DOUBLE MEASURING MODE and special AUTO-ZERO circuit that it is available to measure them after cancelation of thermoelectromotive force for error factor when the measurement is made low-resistance especially. This checker is displayed the measured value, judged HI, GO, and LO, and then the signal is output. The measuring speed is changeable and it is selectable AVERAGE/DOUBLE/SLOW etc. And as CONTACT CHECK CIRCUIT and measuring current/abnormal voltage check circuit are equiped as standard, this checker become higher the confidence. And it is available to equip the interface of GP-IB, RS-232C, or Centro Output as optional function.
