My problem: I have a board that is 96" long, when measuring the board length, my machine only measuring 95.624". when I go to calibrate the length measurement my default is 890.368, I have calibrated it to 874.368 to get to where it measures now(the 95.624"). In trying to get to the 96" measurement, the machine will not let me go below the 874.368, I get "Calibration Range Error". The project requires a measurement closer than 3/8". Thanks in advance, any help is much appreciated. Rog
