Part 2/5:
Commencing the calibration test, the input voltage was set at a modest 10 volts. Initially, the temperature stabilized at 187°C, indicating that the heater was functioning properly at lower power levels.
Increasing Voltage to Observe Temperature Changes
To further evaluate the core heater's capabilities, the input voltage was incrementally increased. The next step involved adjusting the input voltage to 20 volts RMS. The temperature response was observed with a settling time of approximately five minutes. After this waiting period, the heater's temperature reached about 48°C, confirming its capability to handle this voltage.
