7. Taking a Reading
Once you have prepared your sample, you are ready to
take readings.
1. Turn the sample drawer knob to the OPEN/LOAD
position and pull the drawer open.
2. Place your prepared sample in the drawer. Check the
top lip of the cup to make sure it is free from sample
residue (remember, an over-filled sample cup will con-
taminate the chamber's sensors).
3. Carefully slide the drawer closed, being especially care-
ful if you have a liquid sample that may splash or spill
and contaminate the chamber.
4. Access the sample temperature menu (press lower
right button) to watch the temperature difference
between the sample and the instrument.
5. Turn the sample drawer knob to the READ position
to seal the sample cup with the chamber. The instru-
ment will beep once, and the green light will flash
once to indicate that the reading cycle has started. In
about 40 seconds, the first measurement will be dis-
played.
