What to do if I get a 'Missing aw calibration!' error on my METER Laboratory Equipment?
The 'Missing aw calibration!' error on the METER Laboratory Equipment (AQUALAB TDL) indicates that calibration is needed at the current measurement temperature due to the temperature sensitivity of the tunable diode laser measurement technique. You can perform an optional factory calibration, or the user can make an offset or multipoint calibration.
Why is the moisture content displayed not correct on my METER Laboratory Equipment?
If the moisture content displayed on your METER Laboratory Equipment is incorrect, there are a few potential reasons. First, the selected model may not be right for the product you're testing. Try toggling through the available models to see if a more appropriate one gives a better reading. If the model is correct but the moisture content is still off, you might need to offset the model. If the model is correct and an offset doesn't work, you may need to create a new model or update an existing one for the product.
How to fix an AquaLab Measuring Instruments that does not turn on?
First, check that the power cord is securely attached to the back of the instrument and plugged into the power outlet. If it still doesn't turn on, a power surge may have blown a fuse. To change the fuses: * Unplug the power cord. * Locate the panel where the power cord plugs in; the fuse box is on the right side of that panel. Press in on the release tab and pull the fuse-holder out. * Pull the broken fuse(s) out and replace with a 1.25-A 250-V fuse. * Replace the fuse-holder and push it into the fuse-well until the release tab snaps in place. * Connect the power cord and turn your instrument on. If the fuse blows again, contact METER for repairs, as a failed component may be causing the problem.
What does it mean when my METER Measuring Instruments says 'Firmware is corrupted'?
If the error message “Firmware is corrupted” appears on the screen, the firmware on the instrument needs to be reloaded. The instrument must be serviced by METER to download new firmware.
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.
What does crystal failure mean on METER Measuring Instruments?
If the message '(Crystal failure)' appears on the screen, the crystal that runs the firmware is having trouble starting. Try cycling the power to solve the problem. If the message continues to appear, METER needs to service the instrument.
Why does my METER Measuring Instruments display no moisture content reading?
If the screen displays no moisture content reading, it 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.
Why doesn't moisture content show up on the screen of my METER Measuring Instruments?
If moisture content does not appear on the screen, it may not have been activated. Go to the Configuration tab, select %Moisture, and select the appropriate model. If no models appear in the moisture content screen, reload them using AquaLink 4 software.
What does it mean if my METER Measuring Instruments says sample is too hot?
If the screen displays a warning that the sample is too hot, it means the sample temperature is too high for the instrument. Ensure you only measure samples that are at the same temperature as the instrument.
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.
