Why does AquaLab Measuring Instruments display no moisture content reading?
This message on your AquaLab Measuring Instruments means the water activity or temperature for that reading is beyond the scope of the moisture sorption isotherm. Ensure that the sample water activity and the instrument controlling temperature are within the scope of the selected moisture sorption isotherm model.
How to fix 'Contaminated mirror' message on AquaLab 4TEV Measuring Instruments?
If the AquaLab Measuring Instruments displays the message “Contaminated mirror,” it means the mirror used for dew point measurements requires cleaning. Follow the cleaning instructions.
What to do if AquaLab Measuring Instruments displays aw below instrument detection limits?
If your AquaLab Measuring Instruments displays aw below instrument detection limits, it means the sample is too dry for the instrument to read accurately. If your sample has a water activity that is less than the detection limits of the instrument, this message appears. You can also try cleaning the mirror and chamber and measuring the sample again.
Why is moisture content not correct on AquaLab 4TEV Measuring Instruments?
If the moisture content displayed on AquaLab Measuring Instruments is not correct, it may be because the model selected is not correct for the product being tested. Toggle through the available models to find a more appropriate one. If the model is correct but still not giving correct moisture content values, it may be necessary to generate a new model for the product or update an existing model.
How to fix AquaLab 4TEV that does not turn on?
If your AquaLab Measuring Instruments does not turn on, check to make sure your power cord is securely attached to the back of the instrument and plugged into the power outlet. A power surge may have caused a fuse to blow, follow instructions to change the fuses. If the fuse blows again, a failed component may be causing the problem.
What does 'sample is too hot' mean on AquaLab 4TEV?
This warning on your AquaLab Measuring Instruments indicates that your sample temperature is too high for the instrument to equilibrate with it in a reasonable amount of time. Only measure samples that are at the same temperature as the instrument.
What does 'aw below instrument detection limits' mean on AquaLab Measuring Instruments?
This message on your AquaLab Measuring Instruments means the sample is too dry for the instrument to read accurately or the mirror may be dirty. If your sample has a water activity that is less than below the detection limits of the instrument, this message will come up. Try cleaning the mirror and chamber and measuring the sample again.
Why is the moisture content displayed not correct on AquaLab 4TEV Measuring Instruments?
If the moisture content displayed is not correct on your AquaLab Measuring Instruments, the model selected may not be correct for the product being tested. Toggle through the available models to find a more appropriate one. If the model is correct but not giving correct moisture content values it may be necessary to generate a new model for the product or update an existing model.
Why does AquaLab 4TEV Measuring Instruments show no moisture content reading?
If the AquaLab Measuring Instruments displays the message no moisture content reading, make sure that the sample water activity and the instrument controlling temperature are within the scope of the selected moisture sorption isotherm model because the water activity or temperature for that reading is beyond the scope of the moisture sorption isotherm.
Why are water activity readings too high or low on AquaLab 4TEV Measuring Instruments?
If your AquaLab Measuring Instruments displays water activity readings on verification standards that are too high/low and a linear offset adjustment cannot be made any higher/lower, it may be because the thermopile in your chamber or the chamber mirror may have become contaminated.
