The Outline
AX-1152D can measure the ultra low resistance from 0.0000mΩ to 1.5000kΩ with high speed, high accuracy.
The unit has DOUBLE Measuring Mode can cancel to measure the thermo electro motive force that caused an error especially when measures ultra low resistance, and specail auto zero circuit, available to measure high accuracy, and high stability.
The unit is indicated the measured value as a digital and outputs signal outside to judge HI, GO, LO decision. It can be switched a measuring speed, selectable from AVERAGE/DOUBLE/SLOW/FAST.
And Contact check circuit and check circuit for measuring current and abnormal voltage are standard equipment, improved the reliability for the measurement furthermore.
The unit can be equipped either one GP-IB/RS-232C/centronics as an option.
