4 - Safety Instructions
If the calibrator is turned on, do not leave the room without an identification or warning
about the high temperature hazard.
Before turning the calibrator off, return the block temperature to values close to the
ambient temperature.
Never remove the insert from the dry block or the thermo-elements from the insert,
while they are in temperatures far from the ambient. Wait until they reach the ambient
temperature so that the heterogeneous cooling of the parts does not jam each other.
If, by chance, a jamming situation happens, refer to item 8.2 - Instructions for Insert
Jamming to proceed properly.
