PID Calibration

The MiniTherm Plus uses Proportional Integral Derivative (PID) control for stable temperature maintenance. The MiniTherm Plus controller is calibrated at room temperature 25°C ± 2℃ (77°F ± 4°F) before shipping. If the temperature of the heating plate is not stable in your usage environment, the controller can be recalibrated by performing PID calibration.
