Linear Error Compensation Setup
This setting allows you to setup compensation factors for linear errors. There are two
methods of entering compensation values Teach mode and Program mode.
Teach mode is an easier way of calculating linear errors by using the DP700 to automatically
calculate the error, by comparing the actual measurement and the physical movement.
The procedure to do this is shown below.
Press the key to Navigate to Linear.

First you must determine the correction factor required.To do this you use the following
equation. (In the following example the standard distance is 500.000mm and the measured
distance is 500.200mm.)
Correction factor = error / actual x 1,000,000
Correction factor = (500 - 500.200) / 500.000 x 1,000,000
Correction factor = -400
Enter -400 from the example above using the numeric keypad
