If it's the dual column type there will be 4 set screws on the right side of the block at the top of the columns. Run the reader head all the way to the bottom then loosen the two on the rear column then snug just one slightly. Find a hammer with a wooden handle and smack the back of the block hard with the handle (not the hammer head) then check the gauge block again. Repeat as necessary.
The two columns raise or lower the readings depending on which way they lean. Generally if they are leaning forward the readings will be longer. Snugging one screw keeps the columns from springing back. The front column is glued in so loosening the screws does nothing.
You should check the gauge over more than just one height, I check every inch for calibration before making any adjustments.
