Likewise to any high precision measurement instrument/tool, mishandling such as dropping a digital level to floor or storing it outside the specified temperature range could affect its accuracy. This is primarily due to structural deformation resulted from mechanical shock on impact when dropped and physical micro-dimensional changes resulted from thermal expansion or contractions when storage temperature exceed maximum specified range.
However, unlike traditional 'bubble' spirit levels and many other digital levels in the market, all Digi-Pas® digital level is built with User's Self-Calibration feature. This feature empowers users to perform their own calibration without the need to sending to 3rd party testing laboratory when minor mishandling the device. At user's convenient work site or field work, User's Self-Calibration can simply reset the Digi-Pas® digital level back to factory preset accuracy whenever he/she is in doubt with the accuracy of the digital level.
