It often happens in workshops that over the years different devices from different manufacturers are purchased as a single solution and also operated separately from each other due to the lack of a solution.

Only when changing the tester results in a changed range of functions (fewer or more functions, larger or smaller measuring range, etc.), the surface is adjusted, but the operation of the surface follows the already known scheme.
