Pass thermocouple probe through this hole
Position thermocouple probe tip in the centre of the nozzle
Figure 7-4
Note: For the Heated Glass Insert, it is not recommended that
temperatures are measured directly above the objective during
calibration. This is because the objective cools that part of the plate.
Either move the objective away from the glass or measure slightly to the
side of the objective as shown (Figure 7-3).
Calibrating Thermosafe Air Heating System
Access to the air nozzle from above will be improved by lifting out the
Metal Heated Insert and moving to one side.
Place the probe of a calibrated thermometer through the small hole on
the side of the air nozzle (see Figure 7-4) until the probe tip is centralised
in the air stream.
After switching on, wait at least 20 minutes to allow the temperature
to stabilise before calibrating.
