1. Installation place
Caution
• Environmental temperature : -10 ℃ to 50℃
• Environmental humidity : Less than 85 %R.H. (Non condensing)
Warning
① Location where installation is not allowed.
• Do not locate the instrument in direct and/or high temperature area.
• Do not use the instrument in a high humid area.
• Do not install the instrument where there are vibrations and shocks.
• Do not use the instrument where there is excess of dusts and fine particles.
• Do not use the instrument where there are corrosive gas and salt and like that.
• Do not install the instrument where there is rapid change of temperature and humidity.
• Do not install the instrument near the devices that are magnetized or generate an electromagnetic field.
• Do not install the instrument where the instrument may be affected by radioactivity or radial rays.
• Avoid the location where chemical reaction may take place such as in a laboratory, or like that.
Use the instrument where the temperature/humidity specifies with the range as follows :
Don’t locate the instrument on the places as follows :
It may cause an unexpected faulty in the instrument.

Caution
Caution
Be sure to check that the power supply is off in connecting each cable. If the work is done while the power is on, there may have the case that
electric shock to the operator or even may have damage to the instrument.
Before supplying the power, check that the indication of power supply voltage/specifications for the instrument and the power going to supply
should be the same. If they are not equal, contact with us.
If you use the instrument without checking them, it may cause a damage in the instrument or electric shock to the operator.
Please consult Co. about the report when not matching. There is danger of causing damage and the electric shock of this instrument when
using it like the uncertainty.
Earth wire should be grounded securely.
When earth wire is not connected, it may cause a malfunction of the instrument or electric shock to the operator.
Before using a new instrument or exchanging the strain gage applied transducer for a new one, be sure to make calibration.
If calibration will not be made, the correct measuring results may not be obtained nor which may cause malfunction in the instrument and there
may exist damage in peripheral equipments. Besides, even though calibration has been made, there may occur the similar case when the results
are not correct, so make calibration, again.
In case of using the instrument, check that the connections are executed properly. If not connected properly, the correct measuring result will
not be obtained, nor it may cause malfunctions of the instrument, damage to the peripheral equipments or even more serious accidents.
When change of setting is made carelessly on the instrument during measurement, correct measured results may not be obtained and it may
cause malfunction in the instrument and even have the possibility of damage in peripheral instruments.
Don’t shock the instrument such as throwing something on it.
If neglected, it may cause destruction of the parts and damage to the electrical circuits.
Don’t remove the cover of this instrument, don’t peel off the panel sheet, and additionally, take this instrument apart.
It may cause a damage on the case and panel sheet, and ruins the environmental factor and operativeness.
At the time of shipment from the factory, the instrument has been plated with a clear sheet on the panel sheet for protective purpose.
In case of application, use the instrument after removing the clear sheet first.
Don’t push the panel sheet on the instrument with the excessive strong force nor push it with sharp edge object such as a driver. If neglected,
it may cause a damage to the panel switch and even have the possibility of damage to resist to environments or operational performance.
