• Left set is IS Central Position 
• Right set is IS Shift. 

Notes

Central position values tend to be near zero (E1 = -31 and E9 = -23 in decimal) and IS Shift values tend to be midway between 0 and 255 (7B = 123 in decimal). 

So the typical values in the photo above are:

• Left = IS Central Position 
• Right = IS Shift

Some lenses have IS Lables with eight figures to enter for IS Shift and Gyro rank, while others have only two. 

The IS Lable above is for the 'EF-S 18-200mm F3.5-5.6 IS' which doesn't have a gyro rack so:

• Left column = Pitch and Yaw for IS Central Position
• Right column (with the four figures) = Pitch and Yaw for IS Shift

George Barroso / FantasTEC Photo Service:

“The IS setting label provided with the Canon replacement part, made perfect sense once I was in the software. 

Its all there, very easy and all alignments fell right in. Testing the lens after the repair (new IS unit) and alignment was perfect.”
