Zusammenfassung:	An apparatus method, and system for detecting a leaking occluder valve is disclosed. At least one measurement instrument is connected to a fluid within a fluid tubing upstream or downstream of a pump element of an infusion device. The pump element is configured to periodically cause a compression of the fluid tubing and to isolate a downstream portion of the fluid tubing from an upstream portion of the fluid tubing when the pump element is operating under a normal operating condition. A response of the fluid is measured when the pump element is caused to compress the fluid tubing and a determination is made, based on the response whether the compression has fluidically isolated the downstream portion from the upstream portion. One or more shims may be inserted into the occluder valve to move the platen away from the pump element during the test to determine a degree of fault.
