5. Операция
Follow these steps for accurate water activity measurement:
- Подготовить Sampль: Разместите свой sample into a clean, dry sample cup. Ensure the sample fills the cup adequately without overflowing.
- Поместите Sampль: Расположите сample cup onto the base of the meter. The magnetic sample holder will secure it in place.
- Равновесие: Решающий шаг: После размещения sample and closing the meter, allow sufficient time for the sample to equilibrate with the sensor. This process can take several hours, or even overnight, depending on the sample type and environmental conditions. Do not turn on the meter immediately.
- Включение питания: Как только сample has equilibrated, turn on the meter while it is still closed on the sampле.
- Измерение считывания: The LCD screen will display the water activity (aw) and temperature. Allow the reading to stabilize before recording the final value.
- Выключение: The device features automatic and manual shut-off options. To manually turn off, press and hold the power button.
