What does pressure sensor failure mean for METER Laboratory Equipment?
The 'Pressure sensor failure' on your METER Laboratory Equipment indicates that the pressure sensor used for water activity measurements isn't working correctly, and METER needs to service the instrument.
Why are the readings slow or inconsistent on my METER Measuring Instruments?
Slow or inconsistent readings on your METER Measuring Instruments can occur due to several reasons. The sample chamber might be dirty, so refer to Section 6 for directions on cleaning the sample chamber. The temperature difference between the sample and the block chamber may be too great; the sample must equilibrate to instrument temperature before a fast and accurate reading can be made. Also, some products absorb or desorb moisture very slowly, and in this case, nothing can be done to speed up the process.
What to do if verification is not correct on METER Measuring Instruments?
If verification is not correct, start by cleaning the sample chamber and components as described in Section 6. If verification is still incorrect after cleaning, perform a linear offset adjustment.
Why is the moisture content displayed not correct on my METER Measuring Instruments?
The displayed moisture content may be incorrect if the selected model is not appropriate for the product being tested. Try toggling through the available models to find a more suitable one. If the model is correct but still gives incorrect moisture content values, consider generating a new model for the product or updating an existing model.
How to correct the model on METER Measuring Instruments?
If you ran a test with the wrong model, toggle to the correct model on the measurement screen using the up and down arrow keys. The moisture content value will update to correspond with the selected model. If the correct model is not available, cycle to the Configuration tab, select %Moisture, and the loaded models will appear. If the model is still not available, load the appropriate model using AquaLink 4 Software.
Why is moisture content not showing up on the Measurement tab of my METER Laboratory Equipment?
If moisture content isn't showing up on the Measurement tab of your METER Laboratory Equipment, it might not be activated. Go to the Configuration tab, choose '%Moisture,' and then select the right model.
What to do if I get a 'Remove sample. Sample is too hot!' error message on my METER Laboratory Equipment?
The 'Remove sample. Sample is too hot!' error message on your METER Laboratory Equipment means the sample's temperature is too high for the instrument to stabilize quickly. Make sure your samples are at the same temperature as the instrument.
Why does the Measurement tab display no moisture content reading on my METER Laboratory Equipment?
If the Measurement tab on your METER Laboratory Equipment displays no moisture content reading, it means the water activity or temperature for that reading is outside the scope of the moisture sorption isotherm. Verify that the sample water activity and the instrument's controlling temperature are within the range of the selected moisture sorption isotherm model.
How to fix a METER Laboratory Equipment (AQUALAB) that does not turn on?
If your METER Laboratory Equipment (AQUALAB) doesn't turn on, a power surge might have blown a fuse. First, check that the power cord is firmly connected to both the instrument and the outlet. To replace the fuse: * Unplug the power cord. * Find the power cord panel and locate the fuse box on its right side. Press the release tab and pull out the fuse holder. * Replace the broken fuse with a 1.25-A, 250-V fuse. Important: Using any other fuse type can damage the instrument and void the warranty. * Put the fuse holder back in until the release tab clicks. Then, plug in the power cord and try turning on the instrument again. If the fuse blows again, a component may have failed, and the instrument needs repair.
What does pressure sensor failure mean on METER Measuring Instruments?
If the message '(Pressure Sensor failure)' appears on the screen, it indicates that the pressure sensor used during water activity measurements is not functioning correctly. METER needs to service the instrument.
