IMPORTANT SAFETY INSTRUCTIONS
V
WARNING
If something abnormal occurs
Request repair from the retailer where you purchased
the product.
Do not open the cover.
Precautions when placing loads on the unit
o If the load receiving area 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.
o Make sure the load is perpendicular to the surface to
which this unit is attached.
o Place 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.
F1 F F2
F is the correct load orientation
F1 is an eccentric inclined load
F2 is an eccentric load
o Be careful to avoid turning and twisting from lateral
loads. This could cause troubles like those described
in the previous item.
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 Make sure coaxiality and perpendicularity tolerances
of 0.02 mm are maintained for the center hole and the
top and bottom surfaces of these products. When using
them, please consider attachment methods as well as
jigs and other parts being used so that coaxiality and
perpendicularity tolerances of 0.02 mm are maintained.
D01197201B Never remove the cover from this unit. Doing so could
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 Use load cells so that loads are distributed evenly across
the entire surfaces of both the top and bottom.
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.
Using a cable with bare lead wires
TEDS
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 sensing.
o Since products that support remote sense.
o 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 Since the cable is directly connected to this unit, use
a specialized cable to increase the length. (Please
consult with us.)
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 60 mm. Do not
apply tension to the cable.
o Conduct load calibrations periodically.
Installation procedures
o Install this unit in a place where the structure is level
and can sufficiently bear the load being used.
o Screw holes for installation are located in four places
each on the top and bottom surfaces.
o The top and bottom screw hole dimensions are different
according to the load cell rated capacity. The screw
dimensions are shown in the tables below.

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).

Precautions when using during calibra-

tion or as a master load cell
Please take the following precautions when calibrating
one of these products yourself or when using one as a
master load cell.
o We recommend attaching plates to the top and bottom
sides and using them when applying loads.
o Consider rigid materials and their hardness for the
plates used for top and bottom so that they are able
to maintain the flatness and parallelism of the load cell
in relation to the load.
o Moreover, by making the load-receiving surface of the
top plate curved, the affects of unbalanced loads, for
example, can be reduced, enabling accurate measurements.
o Refer to the following illustration as an example of use
when considering top and bottom plates.
