2. Applied Operation
Examples of setting amount of linear compensation (Linear compensation)
After the mechanical error is measured, calculate and set the compensation amount as shown in the following
examples.
Addition to or subtraction from displayed value for displacement
L : Length of block gauge
A
: Displayed value for the distance between surfaces A and C
When L > , add a compensation amount to the displayed value.
Set an appropriate positive compensation amount.
Example : If L = 250 mm and = 249.996 mm
If L is converted to 1m (L
×
4),
×
4 = 999.984, so the compensation amount is 0.016 mm.
When L < , subtract a compensation amount from the displayed value.
Set an appropriate negative compensation amount.
Example : If L = 250 mm and = 250.004 mm
If L is converted to 1m (L
×
4),
×
4 = 1000.016, so the compensation amount is – 0.016 mm.
