FourFoxes tracks two kinds of instrument events: quick accuracy checks and full calibrations. Each instrument carries its own cadence for both, in days, and the list shows when the next one is due.
Log an accuracy check (any role, including Production Team)
- Open Food Safety, then Instruments.
- On the instrument's row, click Log accuracy check.
- Enter the actual reading and the result: Within tolerance, Out of tolerance, or Adjusted.
- The first check on an instrument also asks for the method, reason, target reading, and unit. Later checks reuse those from last time, so a routine check is two touches.
- Click Save accuracy check. It records now unless you adjust the time.

Add a full calibration record (admin or owner)
From the Calibration page, add a record with the date and time, method, reason, target and actual readings, unit, and result.
What happens on the result
- Out of tolerance automatically sets the instrument's status to Suspect. Monitoring records taken with a suspect instrument are flagged in the HACCP master log.
- A later passing check or calibration returns the instrument to Active.
Calibration records cannot be edited or deleted after submission. Reviews (a trained-individual sign-off, typed with your full name) are permanent too. Admins and owners who opt in get a nightly email digest when instruments come due.
Recording an out-of-tolerance result takes the instrument out of service on the spot. Plan the recheck before you log it mid-shift.
