To specify that the input data is the actual reading, type “M” and

press the

[TRANSMIT]

key or just press the

[TRANSMIT]

key at the

prompt:

“MEASUREMENT(M)/DEVIATION(D)?”.

For Dual Processing controls, the status bar indicates which process

is being displayed. Press the

[PROC SELECT]

key to change the

active process. You can only access the axes in the currently

selected process.

To specify that the input data is the difference, type “D” and press the

[TRANSMIT]

key at the prompt. The message on row 5 of the Axis

Calibration screen, “MEASURE,” changes to “DEVIATION.”

The control prompts the user to select whether measurement starts at

the most negative or positive position on the axis. To start at the

most positive position on the axis, type “+” and press the

[TRANSMIT]

key at the prompt: “STARTS AT THE MOST +/--?” or

just press the

[TRANSMIT]

key. To start at the most negative position

on the axis, type “--” and press the

[TRANSMIT]

key at

the prompt.

Important: The input data type and the start measurement point are asked

only when there is no data for the axis. If the user wants to change either

of the two, all the data for the axis must be deleted by deleting all

measurement points with the

{DELETE POINT}

softkey.

Entering Axis Calibration Parameters

Use the following steps to enter the Axis Calibration data:

Move the axis to the most negative position on the axis if this

position has been selected as the start point. Otherwise, move the

axis to the most positive position on that axis.

Press the

{INSERT POINT}

softkey. The control reading appears on

row 7 in the ABSOLUTE column.

If the difference option has been selected, 0 is automatically

displayed in the DEVIATION column for the first point entered for

the axis.

If the difference was not selected, the value displayed for the control

reading (ABSOLUTE column) and the actual reading (MEASURE

column) are the same.
