You can easily create a correction in your program to effectively zero the sensor reading: <\/p>\n<p>1.  Determine what the sensor is reading when it should read zero. This is the offset value.<br \/>\n2.  Insert a Math block to correct the value by that amount.<br \/>\n3.  Select the subtraction setting on the Math block and enter the offset value into the b box in the Math block.<br \/>\n4.
