Abstract
The invention relates to a method of checking the working and/or the state of breathing equipment prior to its use, and also to an arrangement for carrying out the method.The breathing equipment includes a control circuit which, in turn, includes a programmed microprocessor (7), a sensor (10) mounted in the breathing equipment and connected to the microprocessor, and an indicating arrangement (11) connected to the microprocessor (7).The inventive method is characterized by activating the control circuit and therewith measuring or determining at least one functional or state parameter, comparing the measured parameter value with a control value, and indicating an acceptable or unacceptable value in the indicating arrangement (11).
