Caution
Improper use of the instrument may cause injury to operators or physical
damage.
POINT
Describes attention and complementary/related information for operations and
settings of CSD-912B.
Safety precautions
For proper use of CSD-912B, be sure to read the “Safety precautions” prior to use.
Location of installation
Caution
Use CSD-912B under the following conditions of temperature and humidity.
- Environmental temperature: 0 °C to 40 °C
- Environmental humidity: Equal or less than 85 % R. H. (Non condensing)
Safety precautions
ii
Waring
To minimize the risk of unforeseen accidents, avoid installing CSD-912B in the
following locations.
- Hot locations or locations exposed to direct sunlight.
- Damp locations.
- Locations subject to vibration or impact.
- Dusty locations.
- Environments containing corrosive gases or salt, etc.
/RFDWLRQVVXEMHFWWRVXGGHQWHPSHUDWXUHRUKXPLGLW\ÀXFWXDWLRQV
- Close to equipment that generates magnetic or electromagnetic radiation.
- Locations subject to radioactivity and radiations.
- Locations such as laboratories where chemical changes may occur.
Caution
Install CSD-912B based on the following dimensions. Be sure to secure enough
space surrounding the instrument.
The following is the dimensions of CSD-912B and surrounding spaces required.

The following is the side dimensions when the BCD output is connected. (The other
connectors attached external control input/output has the same dimensions as those of the
BCD output. )
If you use CSD-912B where it is splashed with drops of water or covered with
dusts, apply the attached gasket for panel mount between the control board
(cabinet) and the body.
By applying the panel mount gasket, the front panel section of CSD-912B becomes
dustproof and waterproof structure equivalent to IP65 (International Protection Code).
Carefully check the direction of the panel mount gasket not to install it upside-down. Install
the gasket in a right position and make sure that it is not twisted.

Power source
Waring
Install cables while the power is turned off.
If you work while the power is turned on, you may get an electric shock or CSD-912B may
be damaged.
Before turning the power on, be sure to check that the display and the

replacing strain gage based transducers.
Without calibration, precise measurement results may not be obtained or malfunctions may
occur, which may cause damages to peripheral equipment.
Recalibrate the instrument if it has been calibrated but produced incorrect results since this
may cause damages to peripheral equipment.
&RQ¿UPWKDWWKHZLULQJLVFRUUHFWO\SHUIRUPHGEHIRUH\RXVWDUWWRXVH&6'%
Incorrect wiring may result in incorrect measurements and malfunctions, which may cause
damages to peripheral equipment and serious accidents.
Do not carelessly change the settings of CSD-912B during measurement.
Changing the settings may cause incorrect measurements and malfunctions, which may
cause damages to peripheral equipment.
Protect CSD-912B from impact or shock. For example, be sure not to strike an
object against it.
Impact or shock may damage the instrument or cause failures in the electric circuits.
Do not disassemble CSD-912B except for operations allowed by this instruction
manual such as removing the liquid crystal display.
Disassembling may damage the case or the liquid crystal display, or affect the durability
and operations.
When the display surface gets dirty, wipe it gently with a soft cloth or a cloth
moistened with neutral detergent or slight amount of ethyl alcohol.
Handle chemicals with great care not to affect human health.

surrounding it.
Damaging the display may cause leakage of liquid crystal. Take care not to get it
in your eyes or mouth. If the liquid adheres to your body, immediately wash it with
soap, etc.
POINT
Never push the display with excessive force. Never push or rub it with a sharp end
of a driver, etc.
Such actions may damage the touch panel, which may affect the durability and operations.

Product summary
1.1. Features of CSD-912B
CSD-912B is a graphic digital indicator to display signals from a strain gage based
transducer (load cell) as weighing values in various weighing systems. CSD-912B has
various functions, for example, to notify weighing states by state display lamps, control
weighing operations, and extend measurement system/weighing system for instrumentation
by connecting external devices.
Color liquid crystal touch panel
The display of CSD-912B adopts a wide viewing angle6.2 inch TFT color liquid crystal touch
panel with high visibility. Without burdensome button operations, you can operate CSD-912B
