Unacceptable errors:
When any computed solution contains a northing or easting error greater than 21 meters; when
more than 2 of the 20 solutions contain a northing or easting error greater than 17. 5 meters;
when any C error is greater than 0. 1; or when any two C errors exceed 0. 06.
(1) Place the ∆R handwheel in DETENT.
(2) Set the HR counter to 1, 000 meters.
(3) Set in values of ∆ t, HW, RL, and EL as given in chart II.
