Abstract: The means to measure battery electromotive force with potential difference meter of low electromotive force box is introduced in the paper. Laboratorial results show this means has high accurate, reliable reproducible, and simple operating, with which the same results were obtained as those by board potential difference meter do. And then, its valid count is 6 digits, RSD is 0.044%. And the method is reliable for measuring electric source electromotive force.

Key words: LOW ELECTROMOTIVE FORCE, BOX POTENTIAL DIFFERENCE METER, ELECTROMOTIVE FORCE
