Calibrate the reading You do not need to do the calibration if you just want to qualitatively detect radiation. However, if you have standard radiation sources with known µSv/h value, you may calibrate the instrument to get accurate readings. The factory default calibration value is for general in-door and out-door measurements. Calibration Select Calibrate form the Main Menu.
Factory reset Select Factory Reset to reset the unit to the factory default settings. Note: The reset will erase all user settings and recorded history data.
