A method is provided for checking the dynamic behavior of a measuring sensor which detects a substance concentration in the exhaust tract of an internal combustion engine operating with excess air, downstream of an NOx storage catalytic converter. In addition to one or more medicaments, the granules are composed of an excipient combination consisting of a superdisintegrant, a dispersing agent, a distributing agent, and a binder and may also include other conventional ingredients such as sweetening and flavoring agents. The connector assembly includes a cam lever assembly for allowing the user to apply a clamping force to the surgical saw blade with minimum actuation force. The amount of light detected by the light detector is dependant on the amount of light blocked by the strip of material.
