ABSTRACT:
In order to check endoscope channels, a predetermined quantity of liquid is led, at a predetermined pressure, through the channel that is to be checked, and the period of time for this is measured and evaluated. The predetermined quantity of liquid is determined via the volume of a liquid container whose outlet is capable of being connected to the channel that is to be checked. A compressed air source subjects the liquid in the container to a predetermined pressure. A sensor registers whether the liquid level in the container has dropped below a predefined value. A control unit measures the period of time within which the predetermined volume of liquid has flowed through the channel that is to be checked.
