2.2 Caring for the instrument after use
c
The following routine must be observed before the insertion
tube is removed and the instrument switched off:
Over 100°C/212°F
If the calibrator has been heated up to temperatures above
100°C/212°F, you must wait until the instrument reaches a
temperature below 100°C/212°F before you switch it off.
Below 0°C/32°F (applies only to CTC/MTC-140 A
models)
If the calibrator has reached a temperature below 0°C/32°F,
ice crystals may form on the insertion tube and the well.
This, in turn, may cause verdigris to form on the material.
To prevent this from happening, simply heat up the
calibrator to 50°C/122°F.
