摘要
The system measures the time from the date of the last intervention and has an actuator, connected to the time measuring instrument. The actuator moves the apparatus (1) from a first, to a second state, when the time measurement attains a first predetermined threshold. The system is then maintained in the second state until the next intervention. The actuator may progress the apparatus from the second to a third state, when a second threshold is reached. The first state may be when the apparatus is energised and the second and third state when the supply is removed. A removable certification card (9) may be entered into the keyboard (10) receptacle (8) to control a fourth state. Information may be displayed on a screen (5).
