TMT-PH300 IR Preheater
USER MANUAL
OPERATION - MODE 2
Operation - Mode "2"
When the preheater is set to Mode "2", the system uses a custom temperature/time
profile to control temperature. The external temperature sensor "b" ("6b" in control
diagram) is used to control the preheater temperature. The external temperature
sensor "c" is used for additional monitoring.
Note: In order to measure temperature
correctly, kapton tape must be used to securely fix sensor B to the PCBA or
component. If sensor B cannot accurately report temperature then the preheater
temperature may run out of control.
