FIELD: measuring equipment.
SUBSTANCE: invention relates to measurement equipment. Built in tachograph (1) has built-in housing (2) in the form of a rectangular parallelepiped and printed circuit board (6) of an instrument system located in built-in housing (2). Printed circuit board (6) of the instrument system is electrically connected to protective module (20) located inside built-in housing (2). Outer wall (18) of built-in housing (2) has wall recess (22) in which bath (26) is housed, which bath accommodates protective module (20) and has rotatable arm (28). Rotatable arm (28) can rotate about axis of rotation (34) between a first position, which fixes protective module (20) in the operating position of the module in bath (26), and a second position which releases protective module (20) to remove it from bath (26).
EFFECT: improved protection against manipulation of data with a simple design of the device.
