The frequency of calibration and/or verification recommended by Sol Solution for the Panda® and Grizzly® is one year, to ensure that all the results given by the equipment are consistent over a reasonable period.
Depending on the risk analysis, the user company may define its own calibration frequency depending on the frequency of use, the users, the working environment, the history, etc.
It should be noted, however, that the longer the interval between 2 calibrations and/or checks, the more the company must ensure that the risk of drift in the measurement system concerned is controlled. A measurement system can drift over time as a result of impact, wear and tear, conditions of use, etc.
