After the overload test is performed, a period of 24 hours shall elapse prior to taking electrical characteristics (final) measurements. 2. The polarization voltage during moisture the moisture resistance tests is applied with the positive lead connected to the coil terminals tied together, and the negative lead connected to the metal strap. 3. DC resistance shall be the last measurement taken in the electrical characteristics test sequence. Changes from previous issue. The margins of this specification are marked with vertical lines to indicate where changes from the previous issue were made. This was done as a convenience only and the Government assumes no liability whatsoever for any inaccuracies in these notations. Bidders and contractors are cautioned to evaluate the requirements of this document based on the entire content irrespective of the marginal notations and relationship to the last previous issue.
