Calibration: checking that thermometers and displays read correctly
Who this page is for: Owner, Branch manager, Supervisor
Calibration records checks that a measuring instrument itself reads correctly against a known reference. Owners, branch managers and supervisors open it from Settings > Calibration. The list shows each check, newest first, with the instrument, the date, the values and the result.
How do I check a thermometer?
Section titled “How do I check a thermometer?”- Put the thermometer in a cup of crushed ice and water and wait.
- In Calibration tap Log a check, choose the check (probe or infrared thermometer) and the instrument.
- Type what it reads in the ice water.
- Swipe Swipe to log check.
The app decides the result from the number: a probe passes within ±1 °C of 0 °C, an infrared thermometer within ±2 °C.
How do I check a fridge, freezer or hot-holding display?
Section titled “How do I check a fridge, freezer or hot-holding display?”Measure the inside with a probe you trust.

How do I check the dishwasher’s final rinse?
Section titled “How do I check the dishwasher’s final rinse?”Run a thermo-strip through a wash cycle. It should change colour (82 °C). Tap Log a check, choose the dishwasher check, choose pass or fail yourself and swipe Swipe to log check.
What happens when a check fails?
Section titled “What happens when a check fails?”An issue opens by itself on the Issues tab, because every reading taken with that instrument since its last good check is now in doubt. Fix or replace it, check it again, and close the issue.
“Nothing to check yet”
Section titled ““Nothing to check yet””The branch has no thermometer, fridge, hot-holding unit or dishwasher in its equipment. An owner or branch manager adds them in Settings > Branches or in the setup wizard.
How often should I check?
Section titled “How often should I check?”Follow your restaurant policy. Inspectors expect thermometers to be checked regularly, and again after a drop or any doubt.
Can I change a check after saving it?
Section titled “Can I change a check after saving it?”No. A check is never edited once saved. Log a new one.
