4. Important Pre-Settings
4.1 Temperature Control
4.1.1 Adjustment of Temperature
External regulations (ISO, AOAC etc) or internal guidelines request a water acti-
vity measurement at a specific temperature (i.e. 25°C). The LabMaster-aw neo
allows a measurement temperature setting between 0°C (32°F) and 60°C (140°F).
To set or change a temperature value, go to Chamber Settings -> Temperature
control and enter the requested temperature in the pop-up keypad.
Deleting the current temperature value sets temperature control to „OFF“
Note: If target temperature has not been reached, a „stability check tempera-
ture“ is activated, stability can not be reached , thus measurement is delayed. A
Retarded (temp) message appears below the stable indicator bar in that case.
Important!
To avoid condensation of water, place sample in measurement chamber only
after target measurement temperature has been reached.
Hints:
• Ideally, measurement temperature should not be lower than sample tempe-
rature. By this, condensation can be excluded.
• If stable parameters are set correctly, a short time condensation (humid
sample, max. 4°C over measurement temperature) can occur and is not an
issue.
