<p>In a method for calibrating a portable first electronic device (1) comprising a first chemical sensor, a determination is carried out whether the first electronic device is located near a second electronic device comprising a second chemical sensor. If this is the case and if optionally other criteria are fulfilled, readings of the first and second chemical sensor are compared. Subject to the comparison, calibration values for the first chemical sensor are derived.</p> |
