F-0021 The inspection sheets that kept a note of the counter difference

(Said to be copied from a binder of monthly elevator inspection sheets. The car carries an instrument that counts the trips it makes, and the remote monitoring side tallies the same count; the copy includes the reconciliation of the two. Entries are excerpted.)

2014-01-20　10:10-11:40　Unscheduled
Inspection at the request of the management association (running at night). Hoisting machine, controller, door operation, leveling: no abnormality. A query of the operation data likewise returned nothing. The car-side counter and the remote tally count the same number by design. Readings noted for reference; from the next visit, the increase since the previous inspection will be reconciled against the remote figure.

The machine-room key is borrowed at the caretaker’s office. Number two.
The door rails take in grit. Clean them at the start of the month.
The caretaker is new. Introduce yourself.
Spare car lights are on the upper shelf of the storeroom.
That is all.
