In connection with very precise digital voltmeters the model 1282 resistors are used as measuring resistors for accurate registration of direct and alternating currents up to 200 A. The compact construction supports universal application. The exceptional low temperature coefficient extends the scope of application a second time.

A typical application is the wide range of quality and reliability testing. Regular measurements give a reliable information of the quality level of parts, instruments and systems.

Technologies already approved with our precision and calibration resistors - which especially guarantee a secure conduction of the dissipation heat - have been transferred to the precision high capacity resistors. Those are designed on four-wire measurement principle. The voltage path is equalized to the customized value and to an accuracy of 0.02 %, (with reference temperature = 23 ?C).
