The Outline
AX-175A can easily measure a wide range of resistance from 0.1Ω to 99.9MΩ, ultra fast speed, and high accuracy.
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 two types of FAST, a type of SLOW.
Contact-check function as a standard equipment: When measure 4 terminals, either one contact failure occurs, judges a defect, outputs a defective signal with C.E (Contact Error) signal outside regardless of its measured value at the same time.
The behavior of contact-check is selectable from premeasurement/postmeasurement/OFF.
Besides, a checking circuit to observe an abnormal measuring current always has set, and outputs NG judgment when terminal trouble of contact condition occurred during measurement.
Shift circuit, solenoid power supply corresponds to DC24V (high speed operation can be by setup), and quality product counter are built in.
