Introducing the T-212 4-Axis Target
The T-212 Target is a 4-axis target that measures:
•
Vertical and Horizontal center
•
Vertical (pitch) and horizontal (yaw) angle
The target works in two modes;
Centering
and
Angular
.
•
Centering Mode
detects vertical and horizontal
displacement or movement. The resolution is .0001
in. (0.001 mm) using the R-1307, or .00001 in.
(0.00025 mm) using the R-358 Computer Interface
•
Angular Mode
detects an angular (pitch and yaw)
displacement or movement. The resolution using the
R-1307 Readout is .0001 in/in (0.001 mm/25.4mm) or
.00001 in/in. (0.00025 mm/25.4 mm) using the R-358
Computer Interface.
Only one mode may be used at a time. To operate the target in
Centering Mode
, a small light shield is
inserted in the front of the target (see Figure 2).
Figure 2 –
Centering and Angular Modes
To switch to
Angular Mode
, remove the light shield and insert the
lens module using the index pin (see Figure 3) to orient the lens
properly. Rotate the module until the index pin is located opposite
the slot in the body of the target, then slide the reference pin into
the slot. The readings displayed in the Readout are converted to
in/in. For example, when inserting the lens, .0023 displays on the
V-axis of the readout. This means the target is tilting down by
.0023 in/in. A minus (-) V-axis reading means the target is
pointing up (see Interpreting Signs on Page 2).
For the H axis, a + reading means the target is pointing to the left
(front of the target is to the left of the back) when looking down
on top and in front of the target. A “-“ H-axis reading means the
target is pointing to the right (see Interpreting Signs on Page 2 ).
