For safe operation
Be sure to read this instruction manual before use.
1. Installation place
●Use the instrument where the temperature/humidity specifies with the range as follows：
Environmental temperature ：0℃to 50 ℃
Environmental humidity ：Less than 80 %R.H. (Non condensing)
(1) Location where installation is not allowed.
Warning ●Don’t locate the instrument on the places as follows :
It may cause an unexpected faulty in the instrument.
・Don’t locate the instrument in direct sunshine and/or high temperature
area.
・Don’t use the instrument in a high humid area.
・Don’t install the instrument where there are vibrations and shocks.
・Don’t use the instrument where there is excess of dusts and fine particles.
・Don’t use the instrument where there are corrosive gas and salt and like
that.
・Don’t install the instrument where there is rapid change of temperature
and humidity.
・Don’t install the instrument near the devices that are magnetized or
generate an electromagnetic field.
・Don’t 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.

(2) Installation
●When installing the instrument, install as referring to the following figures and secure
the space around the instrument.
Each dimensions of the instrument and required dimensions for the environmental
spaces are as follows:
Outline dimensions
Panel cut size
Unit：mm

2. Power supply
Warning ●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.
Warning ●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 us.
If you use the instrument without checking them, it may cause a damage in the
instrument or electric shock to the operator.
●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.
3. Application note
Warning ●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.
Warning ●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.
Warning ●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.
Warning ●Do not shock the instrument such as throwing something on it.
If neglected, it may cause destruction of the parts and damage to the electrical circuits.
