<p>This performs a Tip Cold Junction Calibration (CJC) (<a href="https://ralim.github.io/IronOS/Temperature/">see Temperature for details</a>). This is normally not needed unless you have an issue with tip temperature or your tips are wearing out prematurely. Changing tip lengths does not necessarily mean a calibration is needed. Check first that your tips are not defective, and measured resistance is close to specifications (Pinecil/TS100 short tips 6.2 Ω, long tips 8 Ω, TS80(P) ~4.5 Ω).</p> <p>This calibrates the <a href="https://ralim.github.io/IronOS/Temperature/">Cold Junction Compensation</a> <em>(CJC)</em> for the tip.

<p>Note: offsets are dependant on your tip, temperature sensor, and the MCU. It's the culmination of tolerances at rest. Typical values are 700-1000 range. This is only designed to be used at boot while cold (ambient room temperature), as temperatures drift apart as soon as power is connected. Doing this reading repeatedly could result in wide varience of the offset number and/or incorrect calibration.</p> <p>Note: offsets are dependant on your tip, temperature sensor, and the MCU.

<p>This allows you to change the front button (<code>+/A</code>) to become a boost button when you hold it for &gt; 2 seconds. A boost button changes the soldering temperature for short periods. For example, when soldering a big joint and you need a much higher temperature, hold the (<code>+/A</code>) button down and it will temporarily increase the temperature to your 'boost' setting. When you release the button, the temperature will gradually go back to the normal set temperature.</p> <p>This allows you to change the front button (<code>+/A</code>) to become a boost button when you hold it for &gt; 2 seconds.
