Hi-accuracy calibrator replaces older units

摘要

The Model 526 V/I dc source/calibrator delivers voltages from ±100 nV to ±110 V that are accurate to within 20 ppm/year, and currents from ±100 nA to ±110 mA accurate to within 50 ppm/year. Resolving 1 ppm and stable to 5 ppm, the calibrator uses a remote programming protocol that is fully compatible with earlier Krohn-Hite 522 and Analogic 8200 calibrators, and so can directly replace them in system and production applications.
