The Outline
AX-163B can easily measure a wide range of resistance from 0.00mΩ to 125MΩ, high speed, and high accuracy.
The unit is installed microprocessor to judge the measured value for HI/GO/ LO, outputs signal outside.
The measured value is indicated as ±10.000％/－99.99％～＋25.00％, or resistance value (max.12500 count).
The unit can be switched a measuring speed, both FAST and SLOW can set an integral time each range.
Contact-check function as a standard equipment: When measure 4 terminals, either one contact failure occurs, judges H decision, and outputs HI signal with C.E (Contact Error) signal outside regardless of its measured value at the same time.
The Contact-check is selectable from premeasurement/postmeasurement/OFF.
Besides, a check function to observe the measuring electrical current/electrical voltage always has set, when bad contact situation occurs during measurement, outputs to judge NG decision. Printed-out (based on centronics), RS-232C interface, and set date transfer functions are equipped as standard. Printed-out can be memorized 10,000 of the measuring date, the unit can be measured even though during printing out. Besides it also can be printed out a result of statistical analysis date for 100 unit of its measuring date.
RS-232C (GP-IB is an option) can be set measurement condition such as output the measuring date, standard resistance or limit value, and others.
The function of transfers the setup date can easily and quickly transfers another AX-163B for the same value of a range, standard, limit, is very useful when use two units together (joint cable is sold separately)
Besides, for setup of a measuring range to handle a key of front panel is only put in a standard resistance value to select automatically an appropriate range built in microprocessor so as to remove the burden of setup a range.
Moreover, a content of the setup keeps by battery backup even the power source OFF.
