For the best result, the oil should be in good condition and free of
foreign objects. If water is accumulated in the oil due to melted ice
crystals – the oil must be dried out, by heating it up.
Warning
Do not handle hot fluid.
If the fluid is heated beyond the flash point, it may
constitute a fire hazard.
If the fluid has caught fire, switch off the main power to prevent further
heating of the fluid. Flames are best extinguished by cowering the well
with a non-flammable lid.
Warning
Do not under any circumstances pour water on burning oil. It
might cause a dangerous steam explosion.
3.3.3 Handling of lids
It is strongly recommended to leave the lid on during calibration.
Calibration without the lid may affect the temperature stability and
homogeneity.
