III
For safe operation
Be sure to read this manual before use.
1. Installation place
●Use the instrument where the temperature/humidity specifies within
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 such 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 is high mechanical vibration.
・Don’t use the instrument where there is excess of dust and fine particles.
・Don’t install the instrument near the devices that become magnetized or
generate an electromagnetic field.
・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.
・Avoid the location where chemical reaction may take place such as in a
laboratory.

2. Power supply
●Before supplying the power, check that the indication of power
supply/specification 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.
Warning ●In order to prevent from a damage to the instrument and electric
shock to the operator, be sure to check that power supply is off when
installing each cable.
●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 Notes
Warning ●Before using a new instrument or exchanging the strain gage applied
transducer for a new one, be sure to make calibration.
If calibration shall not be made, correct measured 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 result is not correct, so make calibration again.
Warning ●In case of using the instrument, check that the connections are
executed properly. If not connected properly, correct measured result
will not be obtained, nor it may cause malfunctions of the instrument,
damage to the peripheral equipments or even more serious accident.
Warning ●When change of setting is made carelessly on the instrument during
measurement, it may cause malfunction in the instrument and also
possibilities of damage in peripheral instruments.

VI
Warning ●Do not shock the instrument such as throwing something on it.
It may cause the damage to the case and even have the possibility of
damage to the instrument in resisting to environment.
Warning ●Do not push the panel sheet on the instrument with unnecessary
strong force nor push it with sharp edge object such as driver
It may cause a damage to the case or panel sheet and even have the
possibility of damage to the instrument in resisting to environment or
operational performance.
Warning ●Do not remove the cover of the case and panel sheet, nor destroy the
instrument. They may cause possibilities of damage to the instrument
in resisting to environment or operational performance.
●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.

1. General
The instrument is a digital indicator for the purpose of strain gage applied transducers.
1−1. Features
Main features for CSD−814B are shown as follows:
1) Large load display
The fluorescent character display tube that specifies 22 mm of character’s height is prepared.
2) Bar meter display
Due to the bar meter of 11 DOT, the percentage of present gross weight against the maximum
display value can be displayed at the intervals of 10%.
3) Automatic calibration function
By registering the data of rated output of strain gage applied transducer (X.XXX mV/V),
calibration can be made automatically.

Bar meter display
Bar meter of 11 dots that displays the ratio of present Gross weight against the maximum
display value at the intervals of 10 %.
3
Setting display
4 kinds of set values such as S1,S2,S3 and S4 can be displayed.
4
Judgement display
Compared result due to comparator function can be displayed.

Status display
RUN : Lights up when the instrument is in the Measurement mode.
It is possible to turn off by the function setting.)
A/Z : Lights up when TARE (A/Z ON)is executed. On the other hand, lights off when Tare
is cancelled(A/Z OFF).
LOCK : Lights up when shorted between the input terminals of LOCK and COM.1 for
external control. During lighting up, front panel key operation can not be made.
HOLD : Lights up when shorted between the input terminals of HOLD and COM.1 for
external control unit.
CHECK : Lights up when the CHECK is ON with the key pressed.

Also used when the target for fine adjustment is changed into whichever “ZERO” or “SPAN”
in fine adjustment on ZERO/SPAN.
12
key
Used when ON/OFF operation is made for the CHECK value. Also by pressing the key
together simultaneously, ZERO/SPAN fine adjustment can be entered.
13

3. Installation procedures
3−1. Installation place
●Use the instrument where the temperature/humidity specifies within
the range as follows:
Environmental temperature : −10 ℃to 50 ℃
Environmental humidity :Less than 85 % R.H.(Non condensing.)
3−2. Location where installation is not allowed.
Warning ●Don’t locate the instrument on the places such as follows:
It will 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 is high mechanical vibration.
・Don’t use the instrument where there is excess of dust and fine particles.
・Don’t install the instrument near the devices that becomes magnetized or generate an
electromagnetic field.
・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.
・Avoid the location where chemical reaction may take place such as in a laboratory.
