Calibrating Heated Plates
Place the probe of a calibrated thermometer in good thermal contact
with the surface.
Note:
Simply touching the probe on the surface is not
adequate. Use a purpose-made surface probe or use thermal transfer
paste. Products sold for computer heatsinks are suitable, and RI can also
supply suitable materials.
Note:
When the system is fitted with the Heated Stage Plate and Heated
Metal Insert, these must be calibrated independently.
After switching on,
wait at least 20 minutes
to allow the temperature to
stabilise before calibrating.
Recommended positions for temperature measurement during
calibration of heated plates are shown below for both metal
(Figure 7-2) and glass (Figure 7-3) heated stage options.
Temperature calibration can be performed on each of the heating options
listed at the start of the Temperature Control section. The calibration
screen is accessed by pressing the
Settings
icon on the main screen, then
the
Calibrate Sensor
icon.
The displayed temperature is adjusted using the
Increase
or
Decrease
icons until the value matches that of the thermometer used to perform
the calibration. Following calibration and after returning to the main
screen, it is advisable to leave the probe in position for a short while in
order to verify that temperatures are as expected. The recommended
method of calibration is described below.
