Abstract
A pressing tool apparatus with a clamping pincer and a sensory mechanism that permits a measurement of a displacement which the piston covers with the closure procedure of the clamping pincer. With the first closure of the clamping pincer, without a pressing, there results a nominal displacement value which is realized by a displacement sensor and a ring magnet. Electronics in the housing store a measured nominal value and compares it to subsequent closure procedures with a pressing, accounting for programmable tolerance values. Pressings within a permitted range or outside the range are suitably displayed.
