2. Important notice for safety
2-1. Warning cases
WARNING
Do not open the main unit cover with power on.
・ There is the high voltage part inside, you may receive the electric shock.
・ As the ultraviolet rays are radiated from the lit-on lamp, do not see it by naked
eyes absolutely. This may cause the inflammation of skin.
・ As the lamp lit on or just after light-on is heated up, do not touch it by hand.
It may cause a burn.
Abnormal heat, fume, abnormal sound and nasty smell
If any abnormality should take place during operation, stop operation immediately, switch
off the power and remove cable from the power socket. If continue to use, it may cause
the electric shock and fire.
Shock such as dropping
Do not do the action to give shock or drop.
As this is composed of fine electronics parts, it may become far from normal operation
and measurement.
・ Operation at place with high temperature, humidity and plenty of dust.
・ Do not store or operate at high temperature, humidity and plenty of dust. It may
cause trouble action, electric shock and fire. The operation shall be made at the given
range of temperature and humidity.
・ When desired to move from low temperature place to high temperature place, there
is the case of dew inside or on the surface. The operation in such may cause the
trouble. When move the product, leave it for some hours alone at the operation place
and let it used to the ambient temperature.
When use the deteriorated parts
・ Check the pipeline regularly and replace the appropriate parts regularly. When
continue to use the deteriorated parts, it may cause breakage of pipe and exploded
accident.
・ The lamp which passes away life excessively may cause explosion.

WARNING
・ OPERATION POWER
Do not use other power voltage than the described. It may cause the breakage of
product, electric shock and fire.
・ Connection of earth terminal(grounding)
For safety, connect the power cable to electric outlet with earth (3P).When use the
accessory transducer plug, ground the earth terminal. If not grounded, it may cause the
electric shock.
・ Handling of power cable
・ Do not put things on the power cable, pull in, push out, bend or slice. As power cable is
damaged, it may cause electric shock and fire.
・ When plug in and out the power cable into electric outlet, be sure to do it with power
plug grasped. When pull the cable, a part may be disconnected and cause the fire.
・ Check that there is no dust on the power plug and plug into electric outlet fully. Then do
not use the loose electric outlet which may cause the contact failure. It may cause fire.
・ When plug in the power cable, do not touch it by wet hand. It may cause the electric
shock.
・ Do not make power tapping hub.
Do not connect many cables into the same electric outlet. This may cause the fire and it
may affect other product by power shutoff of breaker due to over use of power. This is
subject to commercial power electric noise and may easily cause the trouble.
・ Intrusion of foreign substance
Do not put other material than the measuring goods from the sample door. Then, add the
metal material or flammable material inside from the windows. When use as it is, it may
cause the faulty action, electric shock and fire.
・ Put thing on the product
Do not put small metal goods such as pin, clip and container with water such as vane,
plant. When they put inside and operate it as it is, it may cause the damage of products,
the electric shock and fire.
・ When install or move the unit
The unit is big, heavy and precision instrument. So, the vibration may influence on the
unit. When install or move, don’t give the vibration to the unit.And don’t fall it.
When install or move, we recommend that you contact and ask us to install or move.

product, there is the case that the correct measurement cannot be carried out
and the attention for it would be required. When use such walky-talky etc, use
it where there is no influence.
・ Procedure of power on
Make power on after Operating System (OS) for Personal Computer is set up.
If the power gets on before Operating System is set put, it may cause the
error of operation.
・ Power on again
When make power on gain, do it in 5 minutes again after power off. When
make power on within 5 minutes, there is the case that the normal operation
cannot be carried out.
・ Operation at the unstable place
Do not put it at the unstable place such as slant and vibrating place. It may not do the
normal operation.
・ The caution for compressed air
When the following material is contained in the compressed air, it may deteriorate the
detector and dry air generating conditioner and there is the possibility for damage.
Kind Materials which should not contain
Solvent Acetone, Benzene, Phenol, Toluene, Trichloroethylene, Xylene,
Cresol, Thinner, Aniline, Chloroform, Alcohol, Dioxane,
Tetrahydrofuran, Methylene chloride, Cyclohexanone, Carbon
tetrachloride etc
Acid Sulfuric acid, Nitric acid, Hydrochloric acid, Acetic acid, Acetic acid
etc
Gas Chlorine, Sulfurous acid, Hydrogen sulfide, Bromine,
Semiconductor gas etc
Oil Hydraulic fluid (Phosphatic Ester), Fuel oil, Water Soluble Cutting
Fluid (Alkaline), Kerosene etc
・ When use at more than given pressure, it may damage dry air generating
system.
・ When induct liquid such as water from the compressed air pipe, it may
damage the system.
・ When induct other gas such as N2 gas, oxygen, inert gas than air from
compressed air pipe, it may damage the system.
・ When a PC is connected, use it according to operating environment
conditions of the
p
roduct.
