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.

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

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

with HOO designated, offset amount will not be
changed. Execute TLM operation by moving the

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.
