Replace Counter
Press the
4
key to edit the replace counter. The count that you enter will raise an alarm to signal the
operator that it is time to replace the thermode. Thermodes ultimately fail due to repeated heat cycles
that cause internal cracking, slowing down heat generation in the thermode. In addition, repeated
heating cycles cause the thermocouple junction to oxidize and, eventually, break free of the thermode.

parameters of the heat profile on the graphic display. The
