For switching the simulated input resistance in inspections! Achieving a significant reduction in inspection time and errors through automation!
The "ADR Series" is a digital precision variable resistor that allows for resistance value switching from a computer. It enables the automation of inspections, replacing traditional dial-type resistors, significantly reducing inspection time and human error, making it suitable for tests and inspections that require switching simulated input resistances. In addition to setting resistance values from the numeric keypad on the main panel, it also has built-in data for platinum resistance thermometers according to JIS standards (JIS C1604/IEC60751), allowing for temperature-based input. The resistance element uses our ultra-precision metal foil resistors, which excel in temperature characteristics and long-term stability, achieving high precision and high stability. 【Features】 - Computer control via GP-IB and RS-232C connection - Miniaturization compared to conventional models - Utilizes ultra-precision metal foil resistors internally - High-speed switching to any resistance value in under 100ms - Achieves 61/2 digits with an accuracy of 0.01% + 2mΩ *For more details, please refer to the PDF document or feel free to contact us.

Company information
Alpha Electronics has been providing engineers around the world with "high stability, high precision, and reliability" since 1978 as a manufacturer of Bulk Metal® Foil Resistors. Metal foil resistors are adopted as key components in various products that require precision and reliability, such as automatic test equipment (ATE), precision measuring instruments, electronic scales, aerospace, laboratories, calibration equipment, industrial instruments, semiconductor manufacturing equipment, medical devices, and high-end audio. Our excellent metal foil technology allows us to supply standard resistors that can be used in typical room temperature environments. Alpha Electronics is participating in a joint development program for metal foil resistor standard resistors with the National Metrology Institute of Japan (NMIJ). We aim to connect our solid steps in technology, reliability, and development to the future, striving to be a company with technologies and roles that resonate with the next generation, and we will continue our relentless challenges.
