Abstract: A surgical stapling instrument includes an anvil assembly, a reload assembly, an adapter assembly, a processor, and a memory. When clamping to a target pressure, the instructions cause the surgical stapling instrument to advance the anvil assembly in relation to a staple cartridge supported on the reload assembly to a first position to define a first tissue gap within a predetermined acceptable range of tissue gaps, measure a first force of tissue compression of tissue clamped within the first tissue gap with the anvil assembly in the first position, and enter a firing mode of the surgical stapling instrument if the first force of tissue compression is within a predetermined acceptable range of tissue compression.
