Odom, M K

The Primary Standards Laboratory (PSL) presently uses a manually operated dc bridge to calibrate standard platinum resistance thermometers (SPRTs). The PSL will replace the dc bridge with a computer controlled ac bridge. The two bridges are compared for calibrating SPRTs. The results show that the two bridges are interchangeable within <3m/degree/C in the PSL environment. 5 refs., 9 figs., 7 tabs.
