The Outline
AX-150A can measure a wide range of resistance from 1mΩ to 99.9MΩ,ultra fast speed, high accuracy. The unit can be shown the measured value as a digital indication, and also outputs a signal outside to judge HI/GO/LO. It can be switched a measuring speed, selectable from 2 types of FAST, a type of SLOW.
The unit can be equipped Contact-check function as an option: When measures 4 terminals, if either one occurs contact failure, judges a detect regardless of its measured value, and outputs failure signal outside and C.E. (Contact-check error) signal all together.
The behavior of Contact-check is selectable from premeasurement/postmeasurement/OFF with a switch of a behind panel.
Also it sets [a checking circuit of an abnormal measuring current] has always watching a measurement current, outputs NG judgment when terminal trouble of contact condition occurred during measurement.
Either shift output-solenoid power supply or BCD date can be placed as an option.
