Notes:
1. The above data are data measured in a constant temperature chamber in which the
temperature surrounding the equipment was kept at 45°C. They are not the same as the
data obtained from measurements using the exclusive box in which the equipment is
normally used.
2. When using the box, the ambient temperature around the equipment will differ depending
on the air circulation conditions of the box, and the temperature rise inside the cartridge
will differ because of this, so please exercise caution.

Air purity

Air purity in the device environment is expressed by the number of dust particles per unit area and
must be class 5 millions (equivalent to 0.15 mg/m
particles of 0.5 !m dia. or larger per cubic foot)
