4. SETTING UP THE MEASURING CONDITIONS
4.3 Positioning a Gage or a Workpiece
1. Position the calibration gage or workpiece so that it is located at the middle of the mea-
surement position.
The shaded section in the following diagram is the measuring region where the rated
measuring accuracy of this system is obtained.
2. The measured data is displayed even if a workpiece or a gage is located outside the
measuring region, however, the measurement accuracy becomes worse than that of the
guaranteed measurement accuracy.
3. Dimensions A, B, C, and D will vary depending on the Measuring Unit used. Refer to the
specifications and dimensions described in the user’s manual that comes with each
Measuring Unit.

4.4 How to read-in the amount of light
For measurement of the fine gap where the light passing through it can not be sufficiently
secured it is necessary for the system to read-in the amount of light. For more information
refer to Section 3.2.16, “Recording in the amount of light”.
Step 1: Removal of obstructions
Remove any objects (workpiece and fixture) that obstruct the laser path before
reading in the amount of light.

Step 4: Press the
ENT
key while is flashing.
If a sufficient amount of light is detected as a
result of this positive check, the operation auto-
matically returns to the ready state. If is
displayed, it indicates that the amount of light is
insufficient. If this is the case, remove any
obstruction and cancel the error with the
C
key, then perform step 4 again.
