1. Drill a Ø 6x10 mm hole in the body of the machine with
a 30 mm centre distance from the shaft to t the rear
referring pin.
2. Fit the indicator onto the shaft and make sure that the
referring pin ts into the hole.
3. Clamp the bushing to the shaft by tightening the grub
screw with hexagon socket and cup end, according to
UNI 5929-85.

7. Operating mode
7.1 Absolute / incremental measuring mode selection
Press the key to select the absolute or incremental
measuring mode.
The measuring mode selected is shown on the display by
the symbols:
-
ABS
: absolute measuring mode
-
REL
: incremental measuring mode
It is possible to change the key function by
setting the parameter
___0__
The available options are:
-
ArCLr
(default): passing from
ABS
to
REL
the
counter is set to zero.
-
Ar
: passing from
ABS
to
REL
the counter is not set to
zero. In this case, the counter is set to zero by pressing
+ .
-
OFF
: the key is disabled and does not allow
changing the selected measuring mode.
To program the parameters listed above, see paragraph 8.2.

It is possible to change the key function by
setting the parameter
_____0
The available options are:
-
ALL
(default): units of measure that can be selected: mm,
inch, D
-
nodEG
: units of measure that can be selected: mm, inch
-
OFF
: the key is disabled and does not allow changing
the selected measuring mode.
To program the parameters listed above, see paragraph 8.2.
7.3 Setting the absolute reference
After having selected the absolute measuring mode and
stopped the shaft in the starting position
or in the reference position, press the key
combination to set the absolute value to the sum of the
values of the parameters
OriGin
(absolute value of
reference) and
OFFSET
(compensation value).
The value of compensation (offset) allows you to adjust the
value shown on the display in such a way that takes into
account, for example, wear or tool change. The system
allows you to store up to 10 values of compensation. Press
the key combination +. The screen will display the
last compensation value used (eg
OFFS 0
). Choose the
desired compensation value by pressing the key , and
then press the key to conrm.
The screen will display the absolute value to the sum of the
values of the parameters
OriGin
and
OFFSET
.
To program the offset values, see parameter
OFFSET
of
paragraph 8.2.

direct access to the programming of one of
the following parameters, depending on the value assigned
to parameter
0____0
.
It is possible to change the function of the
keys combination by setting the parameter
0____0
The available options are:
-
P_OrG
: direct programming of the absolute reference
value (OrG parameter)
-
P_StP
: direct programming of the reading after one
revolution (StEP parameter)
-
P_OFS
: direct programming of the compensation value
(OFFS parameter)
-
OFF
: the keys combination +is not linked to
any function in the operating mode
