Capable of setting any resistance value with 61/2 digits! High-precision resistors that are less affected by external noise.
The 6-dial decade precision variable resistor "ADR6 Series" features a precision resistor section, a rotary switch section, an output terminal section, and a double shield section, allowing for the setting of any resistance value with a resolution of 61/2 digits, making it a high-precision standard resistor. The resistance element uses our ultra-precision metal foil resistors, and the rotary switch connects three parallel clip-type contacts with extremely low and stable contact resistance. In the output terminal section, wiring using flat copper wire with low thermal resistance minimizes thermal electromotive force, and the adoption of a double shield structure helps mitigate external noise, resulting in a product that achieves high precision and high stability. 【Features】 ■ Achieves accuracy of 0.005% + 2mΩ ■ Resistance temperature coefficient of 5ppm/°C or less ■ Aging change of 50ppm/year or less (when left at room temperature) ■ High reliability through the use of low contact resistance switches and 1 dial with 3 parallel connections ■ Uses low thermal electromotive force terminals ■ Double shield structure makes it less susceptible to external noise *For more details, please refer to the PDF document or feel free to contact us.
