Mitutoyo Measuring Projector PJ-A3005R-50

Compared with ordinary hard glass, the optical glass of the projection lens used for the projector is soft and subject to scratches. In order to remove dust do not use a cloth to wipe the lens, but use a blower brush instead.

To remove oil or fingerprints, dampen clean gauze with a mixture of high-grade alcohol and ether in a ratio of 8 to 2, and wipe gently using a circular motion.

For lens storage, replace the lens cap and store it in its case.

Also replace the lens cap when the projector is not in use, although the lens does not have to be removed from the projector.

-Half-reflecting mirror for surface illuminator

The half mirror for 10x and 20X is coated with a plastic film which tends to collect dust.

Since the mirror surface is subject to scratches, take sufficient care when handling it.

Use a blower brush to remove any dust from the mirror.

-Checking the position of the contour illumination bulb filament

1. Carefully remove the projection lens.

2. Turn on the power switch and contour illumination switch to project the filament of the contour illumination bulb on the screen.

3. Confirm that the filament image is projected in the approximate center of the screen.

-Checking the position of the surface illumination bulb filament

1. Carefully remove the projection lens.

2. Rotate the frame of the surface illuminator condenser lens clockwise until it is fully inserted.

3. Place the half-reflecting mirror (for 10x or 20X lens) on the cross-travel stage.

Adjust the mirror position so that the light from the reflected illuminator is reflected at right angles. Adjust the reflected illuminator position so that the light beam is directed at the center of the mirror.

-Bulbs for contour and surface illuminators

1. To prevent personal injury, do not touch a hot bulb during use or immediately after tuning it off.

2. To prevent the bulb from being stained with oil or fingerprints, do not touch the bulb with your hand.

3. Do not apply force to the bulb pin in the horizontal direction, or the bulb could be destroyed.

(1) Turn off the contour and reflected illumination switches.

(3) Open the door at the right front of the projector.

(4) Pull out the bulb adapter plate.
