Precautions
xii
• Locations subject to direct sunlight or near heating equipment.
• Locations subject to high humidity.
• Locations where the Sensor would accumulate dust, dirt, metallic pow-
der, etc.
• Locations subject to corrosive or flammable gases.
• Locations subject to exposure to organic solvents, water, oil, etc.
• Locations subject to strong electromagnetic or electrical fields.
• Locations subject to rapid changes in temperature.
• Locations subject to freezing.
n Maintenance
(1) Always turn OFF the power supply before adjusting or removing the Sensor
Head.
(2) Cleaning
Do not use thinners, benzine, acetone, or kerosene for cleaning.
If dust or oil adheres to the filter on the front of the Sensor Head, use the fol-
lowing procedure to clean.
• Use a blower brush (used to clean camera lenses) to blow large dust
particles from the surface. Do not blow the dust away with your mouth.
• Use a soft cloth (for lenses) with a small amount of alcohol to remove the
remaining dust. Do not use a scrubbing action when cleaning because
scratches on the filter could result in Sensor inaccuracy.
n Compatibility
All Sensor Heads and Amplifier Units are compatible. Different Sensor
Heads may be purchased at a later date and used with existing Amplifier
Units.
n Controlling Mutual Interference
Mutual interference can be prevented when using two Sensor Heads
together, by connecting the ZX-CAL Calculating Unit between the two
Amplifier Units. However, this effect cannot be attained if the laser beam of
one Sensor Head is received when the other Sensor Head is approaching
saturation. When considering the use of the ZX-CAL Calculating Unit to
control mutual interference, confirm the operation with actual Units in
advance.
