OG exemplary drawing
 
1. A powered surgical instrument comprising:
a processor configured to control operation of the powered surgical instrument;
a memory configured to store a tissue compression program;
a motor configured to control a reload to apply a compressive force to tissue by the reload; and
at least one sensor configured to measure a current draw on the motor,
wherein, when the powered surgical instrument is placed in a reload simulation state to test the powered surgical instrument, the processor executes a simulation program to measure the current draw on the motor during the simulation state when the powered surgical instrument simulates a staple firing through a predetermined nominal thickness; and
wherein the measured current draw on the motor during the simulation state is used to adjust the tissue compression program.
