• Sensor. This displays the TDL sensor as the active sensor on the Measurement tab. This
configuration option is not editable.
• Mode. Select to choose between Single, Continuous, Custom, or Low-Emitting mode
(Figure30). The current mode settings appear at the top of the screen with the number of
tests appearing first, followed by the stability value (∆a
w
).
Figure30 Mode options
 Single mode reads the sample once.
 Continuous mode reads the sample until the chamber lid is opened or the test is
stopped using the CANCEL button.
The AQUALAB reads the sample, displays results, and begins another read cycle without
further action from the user. The machine signals the completion of each reading with a
beep. A timer on the screen tracks the cumulative read time.
All readings taken during Continuous mode are saved on the instrument memory if the
autosave feature is turned on (default).
 ISO 18787 mode reads the sample until the water activity change is equal to or less than
0.0003 a
w
per minute.
 Custom mode reads a sample multiple times until a set level of stability is achieved. For
example, the instrument could be set to read the sample until four consecutive tests are
within ±0.001 a
w
of each other.
Use RIGHT and LEFT to change between the Readings or ∆a
w
settings.
Use UP and DOWN to change to select the number of readings (2 to 9).
Use UP and DOWN to select the ∆a
w
value (any number from 0.0005 to 0.0200) (Figure31).
