1. Calling the operator's attention
Be sure to observe the accompanying precautions in order to safeguard the
operator and preserve the performance of the instrument.
Improper operation of the system may result in severe
Warning
injury of the operator.
Caution
It is a precaution to operate properly.

2. Safety precautions

 Be sure to mount the product properly.
If the product loosens while using it, the product may be detached or
damaged, and operators may be damaged.

3. Mounting

3.1 The dimensions of each transducer are illustrated below.
To mount the transducer, carefully align its sensing direction with the direction
of acceleration and use adhesive.
 Outline drawing of the ASH-A-10 to 50
Indicates the center of mass of the acceleration transducer.
 Outline drawing of the ASH-A-100 to 1K
. Indicates the center of mass of the acceleration transducer.
Warning
3.2 Thoroughly clean the bonding area of the measuring object. Remove dust, oil
and rust from the area using sandpaper and acetone.
Also, thoroughly clean the mounting surface of the transducer.
3.3 Fix with adhesive (cyanoacrylate instantaneous adhesive etc.).
3.4 Be sure to fix the cable to the measurement object as much close as
possible to the transducer mainframe. If circumstances do not allow to fix the
cable to the measurement object, let the cable to slack in such a manner that
it will not be pulled after mounting.
3.5 The transducer cannot be mounted to a curved surface. Use a jig or prepare
a flat mounting area on the curved surface.
3.6 The polarity of transducer output against acceleration
The relation between the direction of acceleration applied to the transducer
and the polarity of transducer output are illustrated below.
Caution
 Do not disassemble the transducer.
 The transducer is very sensitive to shocks. If the transducer is dropped or hit
by a hard matter, thus receiving impact in excess of the allowable overload
rating, damage may be caused. To avoid harm, be sure to handle it very
carefully.
 After the transducer fixation, avoid plucking the cable, swinging around
having a cable, if not, the transducer may be disconnection. Take great care
to handle it properly.
 Install the transducer carefully because its frequency characteristics may vary
depending on the state of installation. The ideal installation is such that the
transducer completely and firmly adheres to a measuring object. Avoid such
manners as to subject the transducer to a bending or twisting force.
 The transducer is not waterproof, therefore avoid using it where it may be
exposed to water or in environments whose humidity is over 85 %.

4. Connection

4.1 Connect the transducer to a strain amplifier.
4.2 Observe the pin assignment of the connector illustrated below.
Caution
 A bridge excitation voltage should be in a range of 2 V. A bridge excitation
voltage other than 2 V does not satisfy the specifications.
 Be sure to start measurement 5 minutes or a longer time after power was
switched on.
