Abstract
A method for automatic checking of the availability of an elevator installation having at least one elevator ascertains at least one first estimated value for a use frequency of the elevator for a first time period and/or a second estimated value for the use frequency for a second time period that begins later than the first time period. A measurement value for the use frequency for the first time period is determined and the measurement value compared with at least one of the estimated values. If the measurement value is smaller by a predetermined amount, at least one predetermined command for carrying out at least one test of the elevator installation is given, wherein in the case of availability of the elevator installation the test leads to a desired reaction. Subsequently, at least one reaction of the elevator installation is registered and compared with the desired reaction.
