Problem/Message Explanation
Printer advances paper
and appears to be
printing, but the paper
is blank.
Check to make sure the paper roll is properly
installed per the instructions in Step 5 — Load
printer paper (Figure 1). The paper must be feeding
from the bottom of the roll, as shown in Figure 1.
RAM Failure This message indicates a memory error with the
system RAM. Try restarting your instrument and
ignore if it does not reoccur. Your instrument may
load factory defaults.
Recalibration Needed
This message indicates that you need to re-
calibrate your instrument. Recalibrate closely
following the instructions in Calibration. If the error
message repeats, obtain Hot-Line Service.
Reset Probe Config
Most likely, this message indicates that you should
reset your block and sample probe bin numbers as
described in Calibration. If this does not solve the
problem, contact Advanced Instruments for Hot-
Line Service.
Result Over Range, Try
Higher Setting
This message indicates the final result is too high
for the low range setting. Select high range and try
again.
Result Under Range, Try
Lower Setting
This message indicates the final result is too low
for the high range setting. Select low range and try
again.
Results not repeatable
(too scattered)
If your results are not repeatable, first check that
your operator technique is sound. Second, use
the A/D test to ensure that your sample probe is
working correctly. If you have questions or if this
does not isolate the problem, please call Hot-Line
Service for assistance.
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.
