Handling Precautions
1. Confirm the input voltage before turning the power switch on
For the input voltage of this microscope, t her e ar e two systems of 100V-system (100
to 120V) and 220V-system (220 to 240V). Connect t he power plug with the plug
socket after conf ir m ing that the rated voltage of the m icroscope corresponds with the
voltage of plug socket.
2. Turn the power sw itch ON or OFF along the order
The counter may display error messages (E51, E52, E53) by the order which turns
the power supply of the microscope main unit and the peripheral equipment such as
personal computer on or off in t he connect ion with some peripher al equipment, when
the peripheral equipment is being connected with the count er unit at RS232C.
Be sure to perform at the following order, when turning the power switch ON or OFF.
• For ON ∙∙∙∙∙ Peripheral equipment Projector main unit
• For OFF ∙∙∙∙ Projector main unit Peripheral equi pment
3. Only use the specified power cord and fuse
Use only the supplied power cord. Replacement fuses must be of t he specified type,
voltage and current.
4. Do not disassemble
Disassembly of any unit or removal of panels may present a hazard to personal or
result in a unit failure. Never att em pt to disassemble, unless absolutely essential, e.g.
for the replacement of a fuse, etc..
This instrument consists of precision components, and its performance cannot be
guaranteed, even within the warranty period, if it is disassembled by the user.
All equipment failures that occur after user disassembly will be repaired on a fee-forservice basis.
Guarantee

MEMO
Overview
This chapter describes the system outline, and the name and
function of each part on the PJ-A3000 series Measuring Projector.
1
1.1 Outline
The Mitutoyo PJ-A3000 series Measuring Projector is a multi-purpose measuring microscope for
factory inspection use. It can perform precision measurement of workpiece dimensions, contours
and surface features.
The PJ-A3000 series can be used in a wide range of applications in combination with a variety of
accessories. It is possible to improve the system according to a specific purpose.
The MF-A series has the following features.
• The cross-travel stage with a maximum stroke of 200 X 100mm is available as an option.
• For the counter display, the readout is easy since the characters are large.
• For the counter display unit, following three types are prepared ; angle and X,Y-axis/ only
angle/ no display
• For both the contour and the reflective light source unit, the halogen bulb of 500 hours life with
24V and 150W is used.
• By the slide switching mechanism, the quick bulb exchange is possible.
• The operability is improved still more, because each switches are placed at the front and right
side of main unit.

Installation and Setup
This chapter describes the installation environments and connection
method of the PJ-A3000 series Measuring Projector.
2.1 Installation
2
2.1.1 Environmental Conditions
2.1.1.1 Temperature
The PJ-A3000 series Measuring Projector has been assembled and adjusted at 20°C in a
temperature controlled room. To ensure the rated measuring accuracy, the temperature at
the installation site must be maintained as close to 20°C as possible, with minimal
fluctuation. (For reference, the conditions specified by JMAS5011 are: 20°C ± 1°C with a
temperature gradient of less than 2°C per 8 hours.) In poor temperature conditions, the
accuracy performance may not be satisfied. It is illegal to make any machine adjustments
affecting the accuracy at ambient temperatures other than 20°C. After such adjustment,
accuracy is no longer guaranteed at 20°C.
2.1.1.2 Humidity
Humidity will not affect the measuring ac cur ac y directly. However, high humidity may
corrode machined surfaces and may adversely affect electronic parts. The environmental
humidity should be maintained within a range of 55% to 65%RH.
2.1.1.3 Dust and dirt
The PJ-A3000 series Measuring Projector consists of high-precision parts, including guide
faces, linear scale units, and optical unit, that must be kept free of dust and dirt. Use and
store the PJ-A3000 series Measuring Projector in a place where it w ill not be subjected to
dust and dirt.
2.1.1.4 Grounding
Connect the ground terminal with the ground terminal of grounding resistance 100 Ω or less
so that the measuring microscope may normally operate.
On the Reinstallation yyyyy The projector main unit reinstallation performed on the client's
own may deteriorate the required accuracy due to vibrations and shocks during
transportation. Therefore, it is recommended that the main unit be reinstalled by Mitutoyo. If
the system is desired to be reinstalled, be sure to contact the Mitut oyo sales office.
TIP
No.99MBA043A 2 - 1
2.1.2 Transportation and installation
Be sure to use the supplied carrying handles when handling, shift ing or installing the projector
and due to its heavy weight (for PJ-A3010F-200, about 120kg) four people are required to
carry it. The PJ-A3000 series has been fully adjusted at the plant, therefore take special care
when handling and setting up the projector so that no part of the projector is subjected to
impact or vibration.
Carrying handles

2.1.3 Setting up the main unit
The projector must be set up on the optional stand or a rigid, stable mount. Use the leveling
bolts on the projector base to compensate for any inclination.

y Loosen the clamp screw and hex-socket head screw on the bracket.
y Slowly insert the stem of the Digimatic Head into the bracket as far as it can go, then
secure it in place with the hex-socket head screw. Do not fasten the screw too tight,
otherwise the spindle of the Digimatic Head will not move smoot hly.

the spindle, the clamp screw is not used to secure it, lightly fasten the screw.
TIP
y The Micrometer Head is provided with a hole for damping the spindle. Align this hole with the
clamp screw. If the display is not in a good viewing position, loosen the clamp screw on the
Micrometer Head sleeve, and adjust the display position.
