IMPORTANT SAFETY INSTRUCTIONS
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
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.
o The screw dimensions are shown in the table below.

Do not use the central
indentation as an installation
surface.

Precautions when placing loads on the unit
o Make sure the load is perpendicular to the surface to
which this unit is attached.
o When using a flat load button, use it so that the load is
equally distributed within a Ø7mm range.
o Apply the load so that it is centered on the center of
the unit. If the load is not centered (eccentric load),
twisting, for example, and measurement errors could
occur. This could even result in damage.

o Be careful to avoid turning and twisting from lateral
loads. This could cause troubles like those described
in the previous item.
o Take extra care if the part that you have prepared is
cylindrical. Even during installation, do not allow loads
to be applied from the side or at an angle as shown in
the illustration below. Doing so could cause the screw
D01416401A 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.
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.
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
part to bend and damage internally.
Moreover, when securing the part, tighten with a torque
of no more than 0.18 N·m or use a threadlocker and
tighten gently by hand.

o A curved load button is used in load testing during
production as shown in the illustration below, and the
results are used in the TEDS data and the test report.
Since the load point, load direction and other condi-
tions differ when using a flat load button, differences in
performance could occur compared to using a curved
load button.

o Be careful to avoid applying loads that exceed the
rated capacity. In particular, use caution when there are
vibrations because loads that exceed the rated capacity
could occur due to sympathetic vibrations, for example.
o If the load receiving area (spherical surface) is contacted
by something that is at a different temperature and the
load is increased, the values output by this device could
become unstable, making accurate measurement impossible.
In such a case, wait until the temperature difference
ceases to exist before measuring.

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.
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.

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.
Electrical connection of load cell with
built-in TEDS
o Connect as shown in the illustration below. Incorrect con-
nections could result in inability to balance and in errors
occurring in the output voltage when loads are applied.

o This unit has a built-in TEDS function.
o The orange and green cores in the cable and the F and
G pins in the connector are wired for TEDS.
o This unit does not support remote sense.
See the operation manuals of indicators and strain
amps that support remote sense for how to connect
sensors with those units.
o The shield is not connected to the main body of this
product. For this reason, if grounding is necessary because
of external noise or another issue, arrange to ground the
shield to a part other than the body of this unit, for example.
o If output values do not stabilize and are difficult to read
due to external noise or other factors when connected
to an indicator, use the filtering function of the indicator.
o Since the cable is directly connected to this unit, use a
specialized cable to increase the length. (Please consult
with us.)
o When conducting insulation resistance tests, limit them
to the red, black, blue and white cores. Do not apply to
the TEDS cores (orange and green).
