Problem/Message Explanation
Sample Freeze Error... This message can be displayed for a number of
reasons. Check your technique and the condition of
your sampler. If neither of these is the source of the
problem, you should check your sample and block
probe numbers. If this does not solve your problem,
contact Advanced Instruments for Hot-Line Service.
Sample Pre-freeze... Test another aliquot of that sample in a clean
sample tube. Check/correct the probe bin
numbers. Correct the stir/freeze wire alignment
and adjustment as necessary. Try to minimize the
effects of materials that tend to cause premature
crystallization. Make sure samples contain no
bubbles or froth before testing. Decrease the
sample stir amplitude, if necessary, to avoid
generating bubbles before the freeze buzz occurs.
If this does not solve your problem, you should
check the probe bin number and obtain service if
necessary.
Sample Probe Failure Switch the instrument off, then on. Check the
sample probe by running the A/D tests. If the error
message does not persist and other error messages
are not displayed, ignore this message. Otherwise,
contact Advanced Instruments for Hot-Line Service.
Sample Probe Open? Switch the instrument off, then on. Make sure the
sample probe is plugged into the main board.
Check the sample probe by running the A/D tests.
If the error message does not persist and other
error messages are not displayed, ignore this
message. Otherwise, contact Advanced Instruments
for Hot-Line Service
Standards Reversed?
Repeat Calibration
This message will appear during the calibration
procedure if the instrument detects that the low
and high calibration standards may have been
mixed up and were entered in the wrong order.
Retry the calibration, being sure that the standards
are correct.
