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

factors involved : shape, size and quantity of workpieces, purpose, required accuracy, etc.
The following methods are basic examples and can be developed further depending on
the particular requirement.
3.4.1 Rectangular coordinate measurement (with the X, Y counter)
Use the cross travel of stage to make dimensional measurements.
Align the datum point of the workpiece with a cross-hair line and take a reading off the
Micrometer Head or built-in counter. Move the cross-travel stage to align the point to be
measured to the same cross-hair line and take a reading. The difference between the two
readings is the dimension of the workpiece (or the distance between the two points).

To actually perform measurement, it is necessary to set up the count direction (count-up or
count-down direction), resolution, etc. Also, if setting compensation constant s for measuring errors
generated according to mechanical operation and various conditions, you can make a
measurement more easily and correctly. These conditions and constants are referred to as
parameters. This subsection describes the function and setting procedure of each parameter.

surface of the scale fits on the screen glass, providing parallax-free measurement.
3.4.4 Comparison with an overlay chart
Measurement and inspection are performed by comparing the workpiece image with the
standard overlay chart which is custom-made for the selected magnification. Use this
method for measurement of shapes, multiple points and dimensions.
This method of measurement is suitable for checking a compl icated part feature which
cannot be inspected in a simple one-dimensional measurement.
Adding tolerance lines onto the standard overlay chart will improve inspection efficiency,
since workpieces can be inspected with reference to these lines.
Standard charts can be made from the workpiece blue print, or the master workpi ece
image projected on the screen. Use transparent or semi-transparent tracing sheets(or
film) to make them. For close inspecti on or for long-term storage, plastic tracing sheets
are recommended because of their greater dimensional stability.

3. Operation
(2) Using the protractor screen and the rotary table for measuring angles:
The cross travel of the stage is normally used in conjunction with the rotary movement of
the table for measuring angles, because it is difficult to align the center of the rotary table
with the vertex of the measured angle.
Align one of the screen cross-hair lines with an edge of the angle to be measured and
read the angle. Rotate the table to align the other edge with the hair line and read its
angle. the difference between the two readings represents the angle of the workpiece
edge. It is not necessary for the angle vertex to remain positioned in the center for
angular measurement, only that the edges be correctly aligned with the cross hair when
readings are taken.
The rotary table No.172-196 can be read in 2' and No.176-106 in 6' increments (using
the vernier scale).

Maintenance
This chapter explains the daily maintenance that must be performed
on the Measuring Projector PJ-A3000 series, including cleaning and
the replacement of consumable parts.
5
5.1 Maintenance of Optical Components
5.1.1 Projection lens
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.
5.1.2 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.
5.1.3 Mirror (surface reflecting mirror)
Since the mirror used in the projector is silvered on its front face rather t han on its back,
unlike ordinary mirrors, it is highly subject to scratches. Ensure it is free from dust or oil.
Should the mirror become stained, use the same cleaning procedure as for the
projection lens. Greater precautions, however, are required for handling the mirror.
5.1.4 Screen glass
Use a soft cloth with diluted neut ral detergent and wipe the glass w hen removing oil and
finger print. After wiping, remove the detergent by wiping with a soft cloth soaked with
water.
No.99MBA043A 5 - 1
5.2 Maintenance of Mechanical Components
5.2.1 Projector main unit
Periodically lubricate the feed screws and gears for the cross-travel stage v ertical travel.
To do so, open the door at the right front of the projector, and apply a thin coat of grease
using a brush. Take care to keep the grease away from other parts of the projector
interior, especially the bulbs.
5.2.2 Cross-travel stage
Remove the cross-travel stage from the stage mount, and apply a small amount of
spindle oil to the V-groove guide rail. Use a soft, dry clot h to wipe dust off the stage glass
and clean the glass gently with thinners or alcohol.

Set the Dip switch DPS1 and DPS2 according to the following.
DPS1 No.1 : ON, No.2 : OFF, No. 3 : OFF, No.4 : OFF 4800bps
DPS2 No.5 : ON, No.6 : OFF
Modify also the parameter setup of the counter simultaneously. (Set "4800bPS" at the
parameter number F7-1 according to "3.4.2 About parameters".)
(Note)
To connect the counter to Micropak 5, unless the default setting are modified, the counter
cannot be connected to Micropak 5. (Because MPK-5 does not accept the Q-axis data.)
Modify also the parameter setup of the counter so that Q-axis output may not be performed.
(Set "2 AS" at the parameter number F8 according to "3.4.2 About parameters".)

(2) QM-Data 200 setup
Select "SYSTEM" key of operation panel.
Measuring Instrument Setting--> Counter Type--> Profile Projector with RS Output
After the selection, the communication condition of QM-Data 200 becomes as follows.
Baud rate 9600bps Data bits 7bit
Parity Even Stop bits 1bit Flow control None
When QM-Data 200 starts, the counter display of projector fades away and LED of
inch/mm display at the counter blinks on and off. The switches on the projec tor
counter become ineffective.
NOTE
6.1.8 Data output (SPC)
While the projector may be used on a stand alone basis, it also has the capability of transmitting data
to external devices through the counter. Incorporating the projector into the M-SPC(Mitutoyo
Statistical Process Control) system permits measurements from the projector to be statistically
analyzed in order to create histograms and process cont rol charts, et c. Data output from the count er
is initiated on the connected processor such as Digimatic Data-Processor. Measurement data
displayed on the counter will be transmitted.
If the projector is being used with a data processor, output data may not be consistent with the
displayed values when the counter is set to z ero.
