How often must magnetometers be calibrated?

Explanation:
Regular calibration keeps the magnetometer accurate by resetting its baseline to account for drift from temperature changes, battery condition, and electronic aging. In a court security setting, where reliable detection of metal is essential, this is done daily before operations begin. Calibrating only after an alarm could let the device drift out of spec and affect readings, while calibrating only weekly or monthly allows drift to accumulate and increases the risk of missed or false alarms. Daily calibration provides reliable performance with practical maintenance.
