AquaLab 4TE Series User Manual

5 MENUS AquaLab
5 Menus
At the top of the display screen there are three tabs: Measurement,
Configuration, and Data. These tabs indicate the three menus you
can access. To change between the tabs press the right most button
below the document icon.
The enter icon is the Read or Enter button. Once the latch is set
to the Read position, the document icon will switch to an “X” icon,
which allows the user to stop the current reading. During a reading,
pressing Enter again will restart the reading.
5.1 Measurement Tab
The Measurement tab, as seen above, is the main screen which dis-
plays each time you turn on your AquaLab. If this screen does not
appear, refer to Chapter 12 for troubleshooting instructions. As
mentioned earlier, the water activity and sample temperature are
displayed on the screen.
Pushing the right or left arrow keys will change the display to a tem-
perature Equilibrating screen. This screen shows the temperature
difference between the sample temperature and the lid temperature.
