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. Doing this will
ensure the most accurate temperature readings.
NOTE: For best results, hold a PCB up to the Thermocouple Nozzle at the same distance as the
nozzle would be from the PCB during the removal or installation process. During the
calibration it is important to avoid holding the PCB in one position too long; this will avoid
board damage during the Automatic Calibration Procedure.
Entering the Automatic Calibration Mode
1. Turn the Power Switch Off.
2. Install the Thermocouple Nozzle.
3. Press and hold the Scroll Up Button (
Release these buttons when software development date appears, e.g., "Dev Date 8-20-04."
