Reference point is the point where measurement
starts.

Measurement is made with the point tem-

porarily determined as coordinate O.

Note:

To display this position as coordinate

O, reset the POSITION [UNIVERSAL] referring
to par. 4.3,4.1.

However the proceeding can

be made normally regardless of this reset.

Exchange the tool with a next tool by manual
operation or by MD I operation.

Even when

the MDI mode is switched on, the

MEASURE-

MENT lamp remains lighted. Return to the
MANUAL mode afterwards.

Repeat the processes f. through h. to store
all the required offset values.

Depress the MEASUREMENT key.

The MEASUREMENT lamp goes out, and the
automatic writing function is turned off.
The length measuring data also disappears

from the CRT.

Notes :

. In this automatic writing mode ,

values are stored in the absolute

values .

when the reference point is different from the tool

change position, the new tool may be brought to
the reference surface directly wfthout

to the reference point. Once the home position

has been set up by the use of the MEASUREMENT
key, repositioning to the reference point is not
necessary.

When

the

& RETRACT key is depressed

with HOO designated, offset amount will not be

changed. Execute TLM operation by moving the
CURSOR AFTER HO1 .

2. Remaining distance measurement

(Pm. #6039D4= “l”)

a. For the set of Pm. #6039D4 = “1”, store the remaining

distance

instead of move measurement

to tool

offset memory.

The bottom level which is used as a base of

calculating remaining distance can be set by

setting #6508 (bottom

setting, 1 = input

unit) .

Writing operation is the same as

described in step 1.
