For safe operation
Be sure to read this manual before operation.
1. Location of installation
Caution
Use the Instrument under the following conditions.
●Environmental temperature : －10 ℃~ 50 ℃(Preservation : －20 ℃~ 60 ℃)
※The temperature span of JIS B 7611-2 conformity is －10 ℃~ 40 ℃.
●Environmental humidity : Less than 85 % R.H.（Non condensing）
Caution
Do not install the Instrument in following places. It may cause damage to the Instrument.
(1) Place to be avoided.
●Places exposed to direct sunlight and/or places in the high temperature.
●Places in a high humid area.
●Places where the instrument is directly affected by vibrations or mechanical shocks.
●Environments containing of corrosive gas or salt, etc.
●Environments with rapid change in temperature and/or humidity.
●Near the devices which generate magnetism or electromagnetic waves.
●Environments vulnerable to radioactivity or radioactivity rays.
●Environments where chemical reaction may take place such a laboratory.

(2) Installing the Instrument
Caution
Please secure and set up the spaces between CSD-903 and the devices.
Followings are the dimensions of the Instrument and for environmental spaces required:

(3) Applicable environment
Warning: The instrument may subject to use in a highly humid area or in full of powder dust.
In such a case, use the instrument by inserting the panel mount gasket attached between the control
panel (cabinet) and the main body.
By inserting the panel mount gasket, the front panel section becomes IP65 (International Protection
Code) or equivalent in dust-proof and water-proof construction.
* Care should be taken when handling the panel mount gasket.

Power supply
Warning
Be sure to check that power supply is OFF when installing each cable. If an operator works with power
ON, he/she may have an electric shock or the instrument may be destroyed.
Warning
Before supplying power, check the indication of power voltage/specifications to be identical with
supplied power. If they are not identical, contact with us. Without checking the above, operation may
cause damage to the instrument or electric shock.
Caution
Be sure to ground a grounding wire. If a grounding wire is not grounded, it may cause malfunction of
the instrument or an electric shock to an operator.
3. Instructions for use
Caution
Before using a new instrument, or when exchanging a strain gage applied transducer for a new one, be
sure to make calibration. If neglected, it may cause incorrect results in measurement or malfunction in
the instrument and moreover may cause damage to peripheral equipments. When similar trouble
occurs after calibration, be sure to make calibration again, even if calibration has completed.
Caution
When using the instrument, check that wires are connected properly. If neglected, correct
measurement cannot be obtained and it may cause malfunction in the instrument or cause damage to
peripheral devices or a critical accident.
Caution
Improper change of setting during operation may cause incorrect measurement or malfunction, or
cause damage to peripheral equipments.
Caution
Do not give the instrument such a shock as throwing something at it.
It may cause damage or destroy electrical circuits and even have loose resistance to environment or
operability.
Caution
Do not 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 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 clear sheet
first.
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 damage to the panel switch and even have the
possibility of damage to resist to environments or operational performances.
