parameters move down one, the current trip is put in (Pr
10.20
=
{tr01,
0.51}
) and the oldest trip is lost from the bottom of the log. Descriptions of the
trips are given in Table 5-8 below. All trips are stored, including HF trips numbered from 20 to 29. (HF trips with numbers from 1 to 16 are not stored in
the trip log.) Any trip can be initiated by the actions described, or by writing the relevant trip number to Pr
10.38
. If any trips shown as user trips are
initiated, the trip string is "txxx", where xxx is the trip number.
