and humidity.
DDon’t install the instrument near the devices that are magnetized or
generate an electromagnetic field.
DDon’t install the instrument where there may suffer radioactivity or
radioactive rays.
DAvoid the location where chemical reaction may take place such as in a
laboratory.

IV
(2) Installation
Warning ●There are a lot of electrical parts installed on the P.C. board of the
instrument, so there have fears to occur electrostatics destruction.
Because of this, operator should discharge electricity from him/her by
touching some metal sections other than the instrument before use.
Besides, take care not to touch electrical parts when you operate.
●When installing the instrument, install as referring to the following
dimensions and secure the space around the instrument.
●When installing the instrument, we recommend you to prepare for
the cover considering the following items.
Besides, we prepares installation to cover for this instrument as
an option.
1 There are a lot of ICs on the P.C. board of the instrument that may
be destroyed eternally due to static electricity, so in order to
prevent the human from touching them directly.
2The battery is installed on the P.C. board of the instrument, so in
order to prevent from shorting between the polarities of battery
carelessly.
3There are some places that have high temperature around 50 ℃or
more in the room temperature, so in order to prevent the operator
from touching the areas carelessly.
●The protection tape for the battery polarities is applied on the part of
battery(front side) and battery terminal(rear side) of this instrument.
When you use the instrument, peel them off.
●The bag for packaging this instrument is made from the conductive
material, so don’t use this bag with the protection tape for each
battery polarities removed.

2. Power supply
Warning ●Be sure to check that power supply is off when installing each cable.
If the work is done with the power fed, there may have the possibility
of electric shock to the operator or even the possibility of destroying
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 us.
If you use the instrument without checking them, it may
cause a damage in the instrument or electric shock to the operator.
●Grounding wire should be grounded securely. When grounding 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 shall not be made, correct measured results may not be
obtained nor it may cause a 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 worse serious accidents.
Warning ●When change of setting is made carelessly on the instrument during
measurement, it may cause malfunction in the instrument and also
possibility of damage in peripheral equipments.

VII
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 ●Don’t push the key switch section on the instrument with
unnecessary strong force nor push it with sharp−edge object such as
driver. If neglected, it may cause a damage to the key switch and even
have the possibility of damage to operational performance.
Warning ●Don’t remove the parts of the instrument, nor take the instrument
into pieces. If neglected, it may cause a damage to the parts and even
have the possibility of damage to the electric circuits.
Warning ●There are a lot of electrical parts installed on the P.C. board of the
instrument, but take care not to touch them. If neglected, there may
cause electrostatics destruction.
Warning ●The P.C. board of the instrument have some sections that have high
temperatures around 50 ℃or more in room temperature for a while
during supplying power or shutting off power supply (”MOD301”,
“U301”, “TR1, TR3 and radiator” indicated on the figure in the next
page.) , so care should be taken not to touch them. If neglected, it may
cause unexpected burns on your skin.
Warning ●The battery is installed on the P.C. board of the instrument, so care
should be taken not to short between the polarities of batteries
unnecessary. If neglected, there may cause remarkable deterioration
of the battery life, damage in the instrument or electric shock to the
operator.

1. General
The instrument is a digital indicator for the application of strain gage applied transducers.
1−1. Features
Main features for CSD−581−74 are as follows :
(1) P.C. board type
Only one piece of P.C. board can perform the function of digital indicator with RS−232C
Interface, and it is suitable for the application inside of control panel.
(2) Automatic calibration function
By the registration for rated output data (X.XXXX mV/V) of strain gage applied transducer,
calibration of the instrument can be performed automatically.
(3) Calibration with RS−232C
Calibration can be performed by the communication through RS−232C.
