AquaLab 12 TROUBLESHOOTING
13. PROBLEM:
Ran test with wrong model.
SOLUTION:
1. On the measurement screen, toggle to the correct model using
the up and down arrow keys. The moisture content value will
be updated to correspond with the model selected.
2. If the correct model is not available, the model may not be
loaded on the instrument.
(a) To determine which models are loaded on the instrument,
cycle to the menu tab, select Moisture Content and then
the loaded models will appear.
3. If the correct model is not available, load the appropriate model
using AquaLink 4 Software. The AquaLab DUO can hold a
total of 100 models at any one time. You may need to re-
move a model using the Software or use the delete option in
the %Moisture Calibration menu before you can add a new one.
Any model that is removed from the instrument with AquaLink
4 will be stored and may be reloaded again later.
14. DUO PROBLEM:
Moisture Content displayed is not correct.
SOLUTION:
1. Model selected may not be correct for the product being tested.
(a) Toggle through the available models to find a more appro-
priate model.
(b) If the model is correct but not giving correct moisture con-
tent values it may be necessary to generate a new model
for the product or update an existing model. For informa-
tion about generating a model, contact Decagon Devices
for updating a model, refer to Chapter 10: DUO Opera-
tion.
