<h3 id="setting-calibrate-cjc-at-next-boot">Setting: Calibrate CJC at next boot</h3>
<p>Note:
If the difference between the target temperature and the measured temperature is less than 5°C, <strong>calibration is NOT required at all</strong>.</p>
<p>This is used to calibrate the offset between ADC and Op-amp of the tip at next boot (Idealy it has to be done at boot, before internal components get warm.). But this setting is <strong><em>not permanent!</em></strong> It resetes after the calibration is completed (At next boot the checkbox will be unchecked!). If you need to repeat the calibration however, you have to set the checkbox <em>again</em>, unplug your device and let it cool down to room/ambient temperature &amp; power it up, idealy while it sits on the desk.</p>
<p>This is used to calibrate the offset between ADC and Op-amp of the tip <strong>at next boot</strong> (Ideally it has to be done at boot, before internal components get warm.). If the checkbox is set, the calibration will only be performed at the next boot. After a successful calibration the checkbox will be unchecked again! If you need to repeat the calibration however, you have to set the checkbox <em>again</em>, unplug your device and let it cool down to room/ambient temperature &amp; power it up, ideally while it sits on the desk.</p>
<p>Also, the calibration will only take place if both of the following conditions are met:
- The tip must be installed.
- The temperature difference between tip and handle must be less than 10°C. (~ ambient / room temperature)</p>
<p>Otherwise, the calibration will be performed the next time the device is started and both conditions are met, unless the corresponding checkbox is unchecked.</p>
<p>Hence, never repeat the calibration in quick succession!</p>
