PRECAUTIONS

(1) Relocation

䃂The Measuring Microscope is a precision instrument. Handle it with care when

transporting/relocating. Do not touch the movable members, which must be secured, during

transportation.

䃂

Place a cushioning pad between the Micrometer Head and the XY stage, as shown below, to

prevent the Micrometer Head spindle from hitting the table.

Cushioning pad

(2) Installation

Install the TM-500 in a site with:

䃂 as little dirt, dust, and humidity as possible. Put the supplied dust cover on it if it is not

going to be used for an extended period of time.

䃂

no vibrations.

䃂

no sudden temperature changes, which may result if the site is subjected to direct sunlight.

(3) Explosive Hazard

䃂Do not operate the Measuring Microscope in the presence of explosive gas.

(4) Power Supply

䃂Depending on the installation site, voltage fluctuation may cause a change in light intensity

or flickering of the illumination bulb. Although this does not affect measurement, use a

voltage stabilizer if a stable light intensity is required.

䃂Use an AC power supply which is isolated from high-voltage, large-current machinery.

High-voltage, large-current machinery often emits a substantial amount of electric noise due

to surge currents, which can adversely affect this measuring system if it draws power from

an AC outlet often provided on such equipment. Therefore, the Measuring Microscope

should draw power from a separate outlet. The power cable of the Measuring Microscope

should run as far apart as possible from such noise sources.

PRECAUTIONS

䃂Only use the power cord that is supplied with the instrument. For a replacement power cord,

contact Mitutoyo.

䃂Only use the supplied replacement fuse or a fuse with identical specifications (type, nominal

voltage and current).

(5) Ground Positively

䃂Ground the Measuring Microscope positively, especially if it must be installed near

equipment emitting substantial amounts of electric noise. To do this connect the grounding

wire from the Measuring Microscope to the body of a piece of equipment, which also must

be grounded. The grounding wire should be as short as possible and should not be wound

into a loop or coil.

(6) Do Not Disassemble

㩷䃂There are high-voltages inside the Measuring Microscope. Do not attempt to disassemble it

unless otherwise specified.

WARRANTY

In the event that the Mitutoyo Measuring Microscope TM-500 series should prove

defective in workmanship or material, within one year from date of purchase for use, it

will be repaired or replaced, at our option, free of charge upon its prepaid return to us.

Outline㩷

This chapter outlines the Mitutoyo Toolmaker’s Microscope TM-500 series and gives the name of each part.

1.1 Description

The Mitutoyo Toolmaker’s Microscope TM-500 series (TM- 505 and TM-510) are easy-to-use, compact-size Toolmaker’s Microscopes that feature a vertical supporting column. Designed with measurement of workpiece contours and inspection of surface features in mind, the TM-500 series supports a wide range of applications from shop-floor inspection, measurement of tools and machined parts, to precision measurement of test tools in a measuring room.

z A long vertical working distance (67mm) and erecting image have improved operability. z The XY stage is mounted on a compact body to support wide travel ranges (50mm㬍50mm

for TM-505, 100mm㬍50mm for TM-510) for effective measurement.

z Fine/coarse focusing can be performed with a single focusing knob. z The angle dial built into the eyepiece portion of the optical tube allows easy angle

measurement.
