Precautions
With the settings in Table 1.2., the safety devices will trip in the succession shown in
Figure 1.2. as temperature inside the chamber rises beyond the target temperature. The
first to trip will be the upper deviation limit alarm, followed by the absolute high limit alarm
and then the overheat protector. Due to the fact that the chamber is equipped with
multiple safety devices, abnormal temperatures cannot escape detection even if one of the
devices is not working properly.
