  Sensor basket – It is very important to place the sensor 
basket in the well, as it ensures that the sensors 
encounter maximum temperature stability and ensures 
that the stirring magnet is not blocked. 
  Silicone oil – Fill the well with oil according to the 
tables of recommended oil volume. The recommended 
volumes must be adjusted to the actual job.  
For oil tables and further oil information – see section 
3.3.2. 
The sensor basket is marked with an optimum fluid level 
mark (100%). When filling the well with fluid and placing 
the sensors, this mark must never be exceeded. 
 
 
Warning 
  Do not pour cold fluid into a hot well – it might cause an 
explosion. 
  Do not pour water or any other fluids into a bath filled 
with hot oil, because only a few drops of water might 
cause a steam explosion, if poured into e.g. above 100°C 
hot oil. 
  Always remove the liquid from the calibrator before 
transportation.   
 
 
 
Caution… 
  Do not use any alkali, acid or ionic fluids in the aluminium 
well as it might be damaged. 
 Be careful not to overfill the well with oil.  
  The oil level rises several centimetres when the 
temperature is rising. Please read instructions in section 
3.3.2 about oil level. To stop overflow switch off the main 
power and the oil level will decrease when cooled down. 
  Remove excess hot fluid with the outmost care, as it might 
be very hot. 
  Do not attempt to remove hot fluid with the liquid drainage 
syringe, as it might melt.
