Log calibrations and accuracy checks

Anyone can log an accuracy check from the Instruments list. Full calibration records are added by admins, and both are permanent.

FourFoxes tracks two kinds of instrument events: quick accuracy checks and full calibrations. Each instrument can carry its own cadence for both, and the Accuracy check and Calibration columns on the Instruments list show when the next one is due.

Log an accuracy check (any role, including Production Team)

  1. Open Food Safety, then Instruments.
  2. On the instrument's row, click Log check. When a check is not due, the row's button shows its next step instead; open the row's ⋯ menu and choose Log accuracy check.
  3. Enter the Actual reading and the Result: Within tolerance, Out of tolerance, or Adjusted.
  4. 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.
  5. Click Save accuracy check. It records now unless you open Adjust time and set an earlier time.

Add a full calibration record (admin or owner)

On the Calibration page, click Add calibration record. Pick the instrument, then enter the date and time, method, reason, event type (Accuracy check or Full calibration), result, target and actual readings, unit, and any notes. Click Save Calibration Record. The button shows Saving... and ignores a second click, so a double-click does not create a duplicate. Future times are rejected. When an instrument is Suspect or its calibration is due, overdue, or never logged, admins and owners also see a Calibrate button on its row on the Instruments list, which opens this form with the instrument already picked.

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 get a nightly email digest when instruments come due or go overdue. It is on by default. Each admin or owner can turn off Calibration reminders for themselves under Email alerts on Account Team.

To hand the records to an inspector, click Export PDF or Export CSV on the Calibration page. The export matches the filters you have applied and covers up to one year. Exporting requires the Member role or higher.

A routine accuracy check: last time's method, reason and target carry over, so you enter the reading and the result.
Out of tolerance benches the instrument

Recording an out-of-tolerance result takes the instrument out of service on the spot. Plan the recheck before you log it mid-shift.
