Figure1 Sample is too hot! message
If this error message appears,
1. Remove the sample from the instrument.
2. Place a lid on the cup.
3. Allow the sample to cool to within 4 °C of the instrument before measuring.
To check the differences in temperature between the sample and the chamber prior to
beginning a reading, set the sample in the chamber, close the lid without latching it, and
press the RIGHT or LEFT button. Figure2 provides an example of this screen.

2.3 TAKING A READING
The AQUALAB TDL provides readings in 5 min or less. Readings are reliable, providing
±0.005 a
w
accuracy.
CAUTIONS
• Never leave a sample in the AQUALAB TDL after a reading has been taken. The sample may
spill and contaminate the instrument chamber if the instrument is accidentally moved
orjolted.
• Never move the instrument after a sample has been loaded. Movement may cause the
sample material to spill and contaminate the sample chamber.
• Do not measure a sample that differs by more than 4 °C than the AQUALABTDL chamber
(Section2.2.2).
