Page 12: Automatic Calibration
The ST 325 System provides precision control of temperature thanks to the closed-loop controlled circuit design. The temperature sensor is located in the heater but utilizing the PACE Thermocouple Nozzle can yield more accurate results due to moving the temperature sensor closer to the component. The Automatic Calibration Procedure allows the system to calibrate for various style components as well as to adjust for any minor offsets in temperature due to heater differences and blower speeds. -
