Installation procedures
To use this product, install one of the included load buttons
(two types) or a part that you have prepared in the central
M2 internal thread as shown in the illustration below.
o Tighten the included load button by hand to the position
where the screw stops.
o Since it could loosen during use, we recommend coating
the screw part with threadlocker. Doing so, however,
will make removing the load button more difficult.
Curved load button Flat load button
o When attaching a part other than one of the included
load buttons, make certain that it does not touch the
cover. (Refer to the dimensional drawings.)
Since the space between the cover and the attachment
area of the loadbearing part is not always uniform, we
recommend using a part that is smaller than the diameter
of the component attachment area.
Furthermore, since the attached part will sink by more
than 30 μm when a load is applied, leave a sufficient
gap between the part and the cover.
o Install this unit in a place where the structure is level
and can sufficiently bear the load being used.
o Screw holes for attachment are located in four places.

V
WARNING
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
cause malfunction. Request inspection and repair from the

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.
V
CAUTION
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.
o The screw size is shown in the table below.

o Refer to the following illustration when using with
tension loading. Moreover, undertake safety measures
to, for example, prevent dropping in the unlikely event
the damage should occur.

o Be sure to use parts that have enough strength to
handle the tension load.
o For the 4 screws used to attach the load cell and for the
central M2 screw, use steel screws with a strength class
of at least 10.9 or screw components with equivalent
strength. Use the longest possible thread engagement
lengths (screw depths) when attaching.

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 Avoid use in conditions where condensation could occur.
o Connect cores to the load cell after discharging (elim-
inating) static electricity from your body.
o If the surrounding temperature changes suddenly, the
values output by this device could become unstable,
making accurate measurement impossible.
(This could occur, for example, in a location blown by
warm or cold air.)
o If a cable of this unit needs to be bent and shifted, make
the curvature of the bent part at least 50 mm. Do not
apply tension to the cable.
o Conduct load calibrations periodically.
o For the jigs above and below, use something that can
absorb load vibrations like rod end bearings.
o When tightening the bolt (nut) on the attachment
side, do not hold the part attached to the load side
of the load cell.

Range of holdable parts
o After installing the part, hold it so that the load is applied
toward the load cell center in the direction of gravity.
