What causes abrupt power loss in Advanced Instruments A2O Measuring Instruments?
If you lose power to your instrument, check that your outlet is providing the correct amount of power. Check that your cord is firmly plugged into both the instrument and the outlet. Visually inspect the fuses, and change as necessary.
What to do if the Advanced Instruments A2O show “Sample Did Not Freeze…”?
If Advanced Instruments Measuring Instruments shows the message “Sample Did Not Freeze…”, test another aliquot of that sample in a clean sample tube. Try testing samples known to be within the range of the instrument.
What to do if Advanced Instruments Measuring Instruments show “No Plateau”?
If your instrument was unable to detect a freezing plateau, and was therefore unable to give a result, check your technique and try again. If the message persists, contact Advanced Instruments Hot-Line Service.
What to do if Advanced Instruments Measuring Instruments show “Sample Pre-freeze…”?
If the Advanced Instruments Measuring Instruments displays a “Sample Pre-freeze…” error, test another aliquot of that sample in a clean sample tube. Make sure samples contain no bubbles or froth before testing. Try to minimize the effects of materials that tend to cause premature crystallization. When testing samples contained in ampules, use a lint-free cloth or swab to carefully remove any liquid film present at the ampule opening. Check/correct the probe bin numbers. When testing low mOsm samples using the Full Range, switch to the Low Range and test another sample. If this does not solve your problem, contact Advanced Instruments Hot-Line Service for instructions on verifying the block probe resistance.
What to do if Advanced Instruments A2O show “Recalibration Needed”?
This message indicates that you need to re-calibrate your instrument. Recalibrate closely following the instructions. If the error message repeats, contact Advanced Instruments Hot-Line Service.
How to troubleshoot a blank print from the Internal Printer of Advanced Instruments A2O?
If the Internal Printer of the Advanced Instruments Measuring Instruments advances paper and appears to be printing, but the paper is blank, check to make sure the paper roll is properly installed. The paper must be feeding from the bottom of the roll.
What to do if Advanced Instruments A2O results are not repeatable?
If you observe that the results from Advanced Instruments Measuring Instruments are not repeatable (too scattered), check the fluid levels in the osmometer and primary carousel tubes to determine whether an insufficient sample volume was dispensed. Also, check the system fluid level, the fluid tubing and connections.
What to do if Advanced Instruments Measuring Instruments results are lower than expected?
If the results from the Advanced Instruments Measuring Instruments are lower than expected, or the last result in a series of replicates is lower than prior results, check the fluid levels in the osmometer and primary carousel tubes to determine whether an insufficient sample volume was dispensed.
