There are two options to copy the data: Option 1: Copy data folder to your PC For this option only the report tool needs to be installed on your PC. 1) Copy whether the data folder, where all measurements are stored, of your instrument, or the folder of the measurement to your PC 2) The easiest way is to copy the folder to the exact same path of the installation folder.
4 Maintenance and Care Regular calibration The Instrument must be calibrated at regular intervals as determined by the accuracy requirements of the application. For most applications a one-year cycle is appropriate. Accuracy specifications are only guaranteed if adjustments are made at regular calibration intervals.
