Temperature readings
Take each unit's reading as often as its setting asks (twice a day by default): at opening and in the afternoon, for example.
A fridge holds food at 4 °C ± 2 °C, so 6 °C at most; hot holding keeps food above 60 °C (Resolución 2674 de 2013, art. 18). The freezer's −18 °C is the app's setting.
When a reading is out of range, write what was done straight away. Take another reading afterwards to show the unit is back in range.
