  2. Reduce spares, save the new first-use date and rebuild.
  3. Check the saved After values before downloading the rebuilt label. Replace the older physical label.

Calculation and observed tool result

Before

Start 2026-11-01 + 14 days = 2026-11-15. Follow product instructions and actual condition.

Recorded quantity: 3 items.

After

Start 2026-11-15 + 14 days = 2026-11-29. Follow product instructions and actual condition.

Recorded quantity: 2 items.

What the result means

The replacement accessory is reviewed on November 29.

Limits of this example

Remove the obsolete label so scanners do not read the previous accessory’s dates.

A mistake to avoid

Resetting the date without subtracting the used spare would overcount reserves.
