This section contains instructions for the
through 7, fig. 16) to zero, if required, by turn-
operation of the test stand under conditions of
i n g the adjustment screw (located below lens
moderate temperature and humidity. Every or-
on center part of meter) clockwise to swing the
ganization equipped with this item must thor-
p o i n t e r to the right, or counterclockwise to
oughly train its personnel in the procedures for
swing the pointer to the left.
o p e r a t i n g this item. For operation under un-
usual conditions, refer to paragraphs 103
cuitry for a direct-driven generator (97b) and
through 106.
