Operating Cautions
•
Place the probe more than 10 cm away from a strong magnetic source.
•
The ground for the circuits inside the probe is electrically shorted to the probe frame.
Therefore, the probe cannot be mounted on a machine with a positive ground.
Also, be sure to ground the probe frame to prevent misoperation due to noise or static
electricity.
•
Do not pull the cable forcibly or pull at the cable when you connect or disconnect it. Such
handling may cause a break in the line.
•
A bellows for dust prevention is installed on the DL310B spindle as standard equipment. It is
not waterproof, however. Be sure not to expose the scale unit directly to water or oil when
operating the unit.
•
No bellows for dust prevention is installed on the DL330B spindle. If the spindle requires
protection against dust, use optional bellows for dust prevention.
•
The bellows for dust prevention is a consumable article.
Purchase a new bellows (optional accessory) to replace it when damaged.
•
Do not oil the spindle. When dust or foreign objects accumulate on the spindle, wipe it using a
dry cloth.
•
The spindle of the DL310B can be air-driven by the pneumatic circuit shown in Fig.1, using a
vacuum pump. Remove the screw at the installation aperture and attach the supplied air lift
joint. Use vacuum pressure in the range 6.0

10 4 Pa. (The air driving feature is
available for the DL310B only.)
Mounting Instructions
•
There are two ways to mount the probe on a machine.
One way (Fig. 3-1) is to chuck the stem using the holder and the other (Fig. 3-2) is to fix the unit
using the installation hole on the stem.
1. Using the holder
Procure a holder of the material and dimensions specified in Fig. 4 and fasten the holder to
a torque of 0.18 to 0.23 N•m to fix the unit to the machine.
2. Direct mounting
Fix the probe to the machine using the M4 screw hole in the front side of the unit.
•
The mounting parallelism affects measurement precision. Adjust the perpendicularity (against
the measuring surface) and parallelism (against traveling) to within 0.3 mm for 100 mm.
•
Fix the cable at a suitable place to prevent the cable lines from being broken.
•
When you use the probe by fixing the spindle to a machine, use the DZ-191 coupling
(optional).
•
