Temperature-time-curve for a sample solution
During a measurement the actual temperature is displayed. The
instrument detects the maximum temperature reached, stores it, and if
crystallization occurred satisfactory, displays the result.
After finishing the measurement the sample vessel is warmed up to 20°C.
As this is the stand-by temperature of the cooling cavity, the measuring
head can remain there before and after measurement as long as desired.
After switching ON the display presents for a short time information
