1962 Science 16 Mar. 950/3 Nanovoltmeter (above) has 13 full-scale d-c ranges from ±0.1 μv to ±100 mv.]
1964 Science 3 July 79/3 Direct-current nanovoltmeter..has full-scale sensitivities of from 10 nanovolts (1 nanovolt = 10−9 volt) to 100 mv.
1968 New Scientist 22 Aug. 391/1 The other problem is how to take just a few microvolts from the national standard of one volt, and to infer its correctness to a few parts of a nanovolt (10−9V).
1994 Physica C. 235–40 3103 Voltage..abruptly changes at some current value with the width of several ten nanovolts.
