Caution…
 
 The well and the insertion tube must be clean before 
use. 
 Scratches and other damage to the insertion tubes 
should be avoided by storing the insertion tubes 
carefully when not in use. 
 The insertion tube must never be forced into the well. 
The well could be damaged as a result, and the 
insertion tube may get stuck. 
 
 
 
 
 
 
 
 
 
 
Caution – Hot surface 
 Do not touch the grid plate, the well or the insertion 
tube while the calibrator is heating up – they may be 
very hot. 
 Do not touch the tip of the sensor when it is removed 
from the insertion tube – it may be very hot. 
 Do not touch the handle of the calibrator during use – 
it may be very hot. 
 
 
Caution – Cold surface 
 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 verdigris to form on 
the material. 
  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 and any water left will 
evaporate. 
  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. 
 Do not touch the well or insertion tube when these are 
below 0°C/32°F – they can create frost-bites.
