Abstract :
We present results of a systematic study of the pressure dependence of the 1.018 V and 10 V outputs of fifteen Fluke 732B electronic voltage standards. Fourteen have relative pressure coefficients near 1.9 parts in 10/sup 9//hPa but one has coefficients an order of magnitude smaller and of the opposite sign. Pressure dependence can produce significant errors in all instruments studied.
