6.3 Thermocouple Replacements
The M330 has two thermocouples; the primary that senses the cavity temperature and the
secondary that measures air temperature inside the heater chamber. The secondary
thermocouple is only used for monitoring the chamber for heat rate control and safety over
temperature shut-down. The image below is the view of the cavity chamber when the M330
front panel is removed.
Warning: Electrical Shock Hazard! This equipment is to be serviced by trained
personnel only.
