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.
