x 1,000,000

S = Standard length

M = Measured length

• In the DRO mode.

• Place a standard of known length on the table. Make sure it’s parallel

with the table’s travel.

• Put the readout in the absolute display mode (

ABS/INCR key).

• Using an edge finder or dial indicator, locate one end of the standard.

• Press the

ZERO key twice for the axis you are measuring. “0” should

appear on the display.

• Move the table along the axis until the edge finder or dial indicator

reaches the opposite end of the standard.

• Write down the length that is shown on the readout display for

that axis.

• Use the formula below to calculate the LEC for the axis you just

measured. Enter the result in the LEC screen (previous page).

Note

: If the measured length is greater than the standard length the

LEC value will be negative.

How to Determine the Linear Error Compensation

Follow this procedure for each axis:

Formula

Example

If the length of the

standard you used is

10” and the measured

length along the X-

axis is 9.995”, then

the LEC for the X-

axis is 500 parts per

million (PPM).
