Measurement㩷 㪊 This chapter describes the preparations for measurement and the measuring procedures. 3.1 Preparations for Measurement 3.1.1Precautions for measurement z Installation site When selecting an installation site, take vibration, dust and humidity into due consideration. Vibration can affect measuring accuracy. Dust and humidity can impair optical parts, such as the objective and prism, and the XY stage and moving parts.
3.1.2 Replacing the lenses An objective (2x) and an eyepiece (15x) are provided with a total magnification of 30x. 1䋮 The following objectives and eyepieces are available as optional accessories. z Eyepiece (10x, 20x) z 5x Objective (working distance: 33mm), 10x Objective (working distance: 14mm) 2. To mount the eyepiece, insert it into the eyepiece mount. The objective can be screwed into the optical tube.
3.1.4 Illumination modes The TM-500 series supports the following illumination modes. Select appropriate illumination mode according to your application. (1) Contour illumination The contour illumination generates the contour image of a workpiece, and is suited for measurement and inspection of workpiece contours. The illuminator is equipped with a green filter. (2) Surface illumination Surface illumination shows the surface of a workpiece, and is used in observation and inspection of workpiece surfaces.
3.1.5 Replacing reticles To replace reticles, use the supplied reticle setting screw, as described below. 1. Pull up and remove the eyepiece. 2. Screw the reticle setting screw into the reticle. Pull out the reticle setting screw along with the reticle. 3. Screw the reticle setting screw into the reticle to be mounted. Insert the reticle into the eyepiece mount. The reticle is provided with a positioning pin. Fit the pin in the groove on the eyepiece mount and insert the eyepiece as far as possible. 4.
3.1.7 Bringing the measuring surface into focus Bring the measuring surface into focus by moving the optical tube up and down with the focusing knob. Look into the eyepiece to make sure the cross-hairs are kept in ocular focus during this focusing operation. If moving the optical tube, be careful, especially if the workpiece is stepped or is secured with fixing jigs, not to bump the workpiece. CAUTION 3.1.
3.2 Measurement 3.2.1 Dimensional measurement Align a measuring point on the workpiece with one of the cross-hairs and take the reading from the Micrometer Head. Then, move the XY stage by turning the Micrometer Head and align another measuring point with the same cross-hair and take the reading at this point. The difference between the two readings represents the dimension between the two measuring points.
3.2.2 Angle measurement Angles are measured with the angle dial, using either of the following two procedures. (1) (2) (1) Align an edge of the workpiece with the cross-hair reticle and align the end edge with the center of the cross-hair. Turn the angle dial to align the cross-hair with the other edge of the workpiece. Take readings from the angle dial. (2) Align two edges of the workpiece with the same cross-hair, one after another, by turning the angle dial and moving the XY stage.
3.2.3 Template matching inspection This Measuring Microscope allows inspection of screw threads and involute gear teeth using the optional template reticles. To perform template matching inspection, set the appropriate optional template reticle according to 㩷 the procedure in "3.1.5 Replacing the reticle". For information about the various template reticles, see "7. Optional Accessories". 3.2.
㪋 Maintenance This chapter describes the daily and periodical inspection and maintenance required to maintain the performance of this microscope. 4.1 Cleaning and Lubrication (1) Main unit Periodically apply a thin layer of grease over the slide guide surfaces and rack of the optical tube using a brush. (2) XY stage Apply a thin layer of spindle oil to guide rails. After dusting the stage glass wipe it gently with a soft cloth.
(3)Focusing knob z Check this knob for any abnormal tightness, play, unevenness, and sound. (4)XY stage z Check the stage glass for scratches and contaminants. z Move the XY stage over the measuring range by hand to check for any abnormal tightness, play, unevenness, and sound. (Perform the same cheek on the stage by turning the micrometer heads.) (5)Angle dial z Loosen the angle dial clamp knob and turn the dial to check for any abnormal tightness, play, unevenness, and sound.
4.3 Replacing Consumable Parts (1) Replacing the fuse When a fuse holder is as in the upper left figure 1. Turn off the contour and surface illumination switches and the power switch, and the pull out the power cord. 2. Insert a screwdriver in the rectangular hole of the fuse holder and raise the screwdriver grip, then a latch will separate and the fuse holder will come out from the front. 3. Replace the fuse, and replace the fuse holder. When a fuse holder is as in the lower left figure 1.
(3)Replacing the contour illumination bulb The bulb remains hot after it has been turned off. Do not replace the bulb until it had cooled down. 㩷 CAUTION㩷 1. Turn off the contour illumination switch and power switch. 2. Remove the stage glass. (See (2) above.) 3. Turn the green filter counterclockwise to remove it. 4. Remove the bulb by turning it counterclockwise with the supplied bulb setter. 5. Mount a new bulb using the bulb setter. 6. Turn on the power switch and contour illumination switch.
(4)Replacing the surface illumination bulb The bulb remains hot after it has been turned off. Do not replace the bulb until it has cooled down. 㩷 CAUTION㩷 1. Turn off the surface illumination switch and power switch. 2. Turn the white filter counterclockwise to remove it. 3. Remove the bulb by turning it counterclockwise with the supplied bulb setter. Mount a new bulb using the bulb setter. 4. Switch the illuminator select switch knob to the surface illumination. 5. Check that the bulb lights. 6.

Troubleshooting 㪌 If a problem occurs, diagnose and remedy the problem with the aid of the following procedures. (1)The contour illumination bulb will not light. Check1䋺 Is the power switch turned on? YES Check2䋺 No Turn on the power switch. Is the contour illumination switch turned on? YES No Turn on the contour illumination switch. Check3䋺 Is the light control knob properly set? Turn the knob clockwise to increase the light intensity (if YES No turned fully counterclockwise).
㩿㪉㪀The surface illumination bulb will not light. Check1䋺 Is the power switch turned on? YES Check2䋺 No Turn on the power switch. Is the surface illumination switch turned on? YES No Turn on the surface illumination switch. Check3䋺 Is the light control knob properly set? Turn the knob clockwise to increase the light intensity (if YES No turned fully counterclockwise). Check4䋺 Is the power cord connected correctly? YES Check5䋺 No Replace the bulb. No Replace the fuse.
(4)The light intensity of surface illumination cannot be adjusted (if the surface illumination switch is turn on ). Check䋺 Is the surface illumination bulb lit? Refer to "(2) The surface illumination bulb will not light". YES No Contact Mitutoyo. (5)The optical tube will not move up and down properly. If there is any abnormal tightness, play, unevenness, or sound when the optical tube is moved, contact Mitutoyo. Should this be the case, do not continue to move the optical tube or disassemble it.
