Do not touch the tip of the sensor when it is removed
from the insertion tube/well – it may be very hot and
cause burns.
Do not touch the handle of the calibrator during use – it
may be very hot and cause burns.
Over 50°C/122°F
If the calibrator has been heated up to temperatures
above 50°C/122°F, you must wait until the instrument
reaches a temperature below 50°C/122°F before you
switch it off.
Do not remove the insert from the calibrator before the
insert has cooled down to less than 50°C/122°F.
Caution – Cold surface
Below 0°C/32°F
(applies only to the RTC-156/157/158/159
/B/C models)
Do not touch the well or insertion tube when these are
below 0°C/32°F - they might create frostbite.
If the calibrator has reached a temperature below
0°C/32°F, ice crystals may form on the insertion tube
and on the well. This, in turn, may cause the material
surfaces to oxidize.
To prevent this from happening, the insertion tube and
the well must be dried. This is done by heating up the
calibrator to min. 100°C/212°F until all water left has
evaporated.
Remove the insulation plug while heating up.
It is very important that humidity in the well and insertion
tube is removed to prevent corrosion and frost expansion
damages.
