2.1 Installation
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 accuracy 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 will 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.

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 Mitutoyo sales office.
