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 ：−10 ℃to 50 ℃
Environmental humidity ：Less than 85 %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 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.

(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
Front Side

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.
●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 Minebea.
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.

VI
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.
Warning ●Do not 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
performances.
Warning ●Don’t remove the cover of the case of the instrument, nor peel off the
panel sheet nor take the instrument into pieces.
If neglected, it may cause a damage to the case and the panel sheet
and even have the possibility of damage to resist to environments or
operational performances.
●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
clearsheet first.
