What to do if AquaLab 4TEV Measuring Instruments shows a warning that the sample is too hot?
To avoid this problem with AquaLab Measuring Instruments, ensure that you only measure samples that are at the same temperature as the instrument.
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.
Why moisture content does not show up on AquaLab 4TEV Measuring Instruments screen?
If the moisture content does not show up on the screen of AquaLab Measuring Instruments, it means moisture content has not been activated. Toggle to menu tab, select moisture content, and select the appropriate model.
What to do if verification is not correct on AquaLab 4TEV?
If verification is not correct on AquaLab Measuring Instruments, it may be because the sample chamber and mirror need to be cleaned. Also, verify and adjust for linear offset.
Why are the readings slow or inconsistent on AquaLab Measuring Instruments?
If you are getting slow or inconsistent readings from AquaLab Measuring Instruments, it could be because the temperature difference between the sample and the block chamber may be too great, the sample needs to equilibrate to instrument temperature before a fast, accurate reading can be made. The sample chamber may be dirty. Some products absorb or desorb moisture very slowly. Your sample may contain volatiles. A fan blade in the block chamber may be broken or bent.
What to do if I ran test with wrong model on AquaLab 4TEV Measuring Instruments?
If you run a test with the wrong model on AquaLab Measuring Instruments, toggle to the correct model on the measurement screen using the up and down arrow keys. The correct model may not be loaded on the instrument. To determine which models are loaded on the instrument, cycle to the menu tab, select Moisture Content and then the loaded models appear.
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.
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.
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.
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.
