Section 11), you may download all readings taken during continuous
mode to the AquaLink 4 software.
Custom Mode: Custom mode allows a sample to be read mul-
tiple times until a desired level of stability is achieved. The user
determines how many consecutive tests they want to be within a
given water activity stability setting. For instance, the customer can
choose to have four consecutive tests be within ±0.001 a
w
. The in-
strument continues to run tests until it records four consecutive tests
that are within ±0.001 a
w
and then stop and report the value of
the final test. If autosave is turned on, all test readings save to the
instrument memory, but only the final reading appears on the main
measurement screen. If the AquaLab is connected to a computer us-
ing AquaLink 4 (see Section 11), AquaLink 4 downloads all readings
taken during a custom mode test.
On the Mode screen at the top of the page, the current mode settings
appear with the number of tests appearing first, followed by the sta-
bility value (∆a
w
). Pressing enter with the custom mode highlighted
allows you to change the number of tests and stability settings.
To change the number of readings, use the right/left arrow buttons
to highlight the number under Readings, and then use the up and
down buttons to change to any value between 2 and 9.
