IMPORTANT SAFETY INSTRUCTIONS
WARNING
V
If something abnormal occurs
Request repair from the retailer where you purchased
the product.
Do not open the cover.
Never remove the cover from this unit. Doing so could
ATTENTION
o When attaching a load button or rod end, for example,
to the screw/bolt area on the top of the load cell, use
the included jig to hold the area shown with diagonal
lines at the top and tighten the screw or nut.
Jig for tightening (commercially-available)
o In the same way, when attaching a rod end or base,
for example, to the screw/bolt area on the bottom
of the load cell, use the included jig to hold the area
shown with diagonal lines at the bottom and tighten
the screw or nut.
Jig for tightening
o When tightening the screw or nut attached to the load
cell, holding the screw/bolt part on the opposite end
(shown with diagonal lines), will cause twisting force
to be applied to the gauge and break the load cell.
D01399001A cause malfunction. Request inspection and repair from the
retailer where you purchased the product. Do not alter this
unit. Doing so could cause malfunction.
Do not put foreign objects or water, for example,
into the unit.
Do not place a container that holds water, for example, on
top of this unit. If liquid is spilled, for example, and enters
the unit, this could cause malfunction.
Do not use the unit with any power supply voltage
other than that specified.
Do not use the unit with any power supply voltage other
than that specified. Doing so could cause malfunction.
CAUTION
V
Unsuitable installation locations
Do not place the unit in the following types of locations.
Doing so could cause malfunction.
o Locations where it might be exposed to smoke or steam,
such as near a kitchen table or humidifier
o Unstable locations, including unsteady stands and
tilted places
o Locations that are very humid or dusty
o Locations that are exposed to direct sunlight
When not using the unit for a long time
For safety, cut the power supply when not using this unit
for a long time.
Do not operate a damaged unit.
Precautions for use
o This unit is not built to be water or splash resistant,
and it cannot be used in conditions when the relative
humidity is high. Moreover, use in atmospheres with
corrosive gases should be avoided.
o Be careful to prevent water, oil and other substances
from getting on the unit.

o When removing it, follow the attachment procedures
in reverse order. On the top or the bottom side of the
load cell that has 14mm width across flats, the side that
has the nut, for example, to be loosened, use the jig
for tightening to remove it so that force is not applied
to the load cell.
o Attach a load button, for example, when using with
compression.
Tighten with the torque shown in the table above
to prevent the load button from becoming loose.
When removing an attached load button, be sure not

A thread-locking fluid can be used on the screw, but
be aware that this could prevent removal of the load
button. Please prepare a load button to attach or
consult with us.
o When using with a tensile load, attach a rod end or
tensile load adapter.
o When attaching a rod end to a load cell, use a nut to
prevent loosening. When tightening this nut for pre-
venting loosening, secure the rod end. Do not tighten
the nut by securing the load cell. If twisting force is
applied between it and the central screw part, the load
cell could be damaged.
o Avoid use in conditions where condensation could occur.
o Connect cores to the load cell after discharging (elim-

Installation procedures
Insert a screw into the screw hole in the center part of the
load cell, and fix the screw to a flat attachment surface.
(Output precision could be affected if the attachment
surface is not flat.) The size of the screws used depends on
the rated capacity (model name) of the load cell as shown
in "Recommended tightening torques when attaching to
load jigs and surfaces" below.

Use screws with a strength grade of 12.9.
In addition, see the "Effective screw depth" in the dimensional
drawing for the length of thread engagement of the screw
and the mounting part (internal threads).
Please consult with us if you are uncertain about screw
selection, for example.
