A practical checklist

  1. Record the meter replacement as a dated maintenance event.
  2. Preserve the old and new observed readings in notes with their sources.
  3. Label later readings as coming from the replacement meter where confusion is likely.
Illustrative recordA worked example

Repair · October 1. Notes: “Meter replaced; old display read 3,120 h, replacement starts at 0 h.” A later 25 h service entry says “Replacement meter reading.” It does not imply the machine has only 25 lifetime hours.

What to avoid

The app does not calculate lifetime hours across meter replacements. Keep any external calculation and assumptions explicit.
