It is important to calibrate!
Each impact recorder supplied by Mobitron is tested and calibrated in accordance with references that have been approved by SP, Technical Research Institute of Sweden. According to the marking on your impact recorder, this calibration should be renewed within 24 months. The year and month for the next calibration are marked at the top of your impact recorder. For more detailed information, see the underside of the battery cover on the impact recorder.
NOTE, to maintain the status and reliability, the calibration should be renewed within the time stated.
