Firmware is corrupted. See
Manual for options.
error message
The rmware on the instrument is corrupted and needs to be
reloaded. To download new rmware to the AQUALAB 4 models, the
instrument must be serviced by METER (Section4.4).
Ran test with wrong model
On the measurement screen, toggle to the correct model using the
UP and DOWN button (Section2.5). The moisture content value
updates to correspond with the model selected. Use SAVE to save
the updated moisture value.
If the correct model is not available, the model may not be loaded
on the instrument.
To determine which models are loaded on the instrument, cycle to
the Conguration tab, select Moisture and the loaded models will
be listed.
If the correct model is not available, load the appropriate model
using AquaLink 4 software (Section2.5.2). The AQUALAB DUO can
hold a total of 100 models at any one time.
Moisture content displayed
is not correct
(AQUALAB DUO)
The model selected may not be correct for the product being tested.
Toggle through the available models to nd a more appropriate
model.
If the model is correct but not giving correct moisture content
values, it may be necessary to offset the model. See Section2.5.4
for detailed instructions.
If the model is correct and an offset does not work, it may be
necessary to generate a new model for the product or update an
existing model. For information about updating or generating a
model, contact Customer Support.
Moisture content does
not show up on the
Measurement tab
(AQUALAB DUO)
Moisture content has not been activated.
Toggle to the Conguration tab, select %Moisture, and select the
appropriate model.
If no models appear in the %Moisture screen, reload models using
AquaLink 4.
If %Moisture is not an active selection, the DUO feature may not be
active. Contact Customer Support to learn how to upgrade to a DUO.
Message on the
Measurement tab displays
no moisture content reading
(AQUALAB DUO)
When a moisture content reading is not shown, the water activity or
temperature for that reading is beyond the scope of the moisture
sorption isotherm. This can happen under the following two
conditions:
• The isotherm equation calculates a moisture content that is less
than 0% or greater than 100% with the given water activity.
• The control temperature is signicantly different than the iso-
therm temperature. Make sure that the sample water activity and
the instrument controlling temperature are within the scope of
the selected moisture sorption isotherm model.
