IMPORTANT SAFETY INSTRUCTIONS
VWARNING
If something abnormal occurs
In the unlikely event that the product produces smoke, a
strange smell or noise, for example, continuing to use it in
this abnormal state could cause fire or electric shock. After
cutting off the power, confirm that smoke is no longer being
produced. Then, 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 electric shock. Request inspection and repair from
the retailer where you purchased the product. Do not
alter this unit. Doing so could cause fire or electric shock.
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. Liquid overflowing or entering the unit
could cause fire or electric shock.
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 fire or electric shock.
VCAUTION
Unsuitable installation locations
Do not place the unit in the following types of locations.
Doing so could cause fire or electric shock.
oLocations where it might be exposed to smoke or steam,
such as near a kitchen table or humidifier
oUnstable locations, including unsteady stands and
tilted places
oLocation that are very humid or dusty
oLocations 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
oThis 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.
oBe careful to prevent water, oil and other substances
from getting on the unit.
oAvoid use in conditions where condensation could occur.
oConnect cores to the load cell after discharging (elim-
inating) static electricity from your body.
oIf 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.)
oConduct load calibration periodically.
Installation procedures
oInstall this unit in a place where the structure is level
and can sufficiently bear the load being used.
oRemove any oil from the mounting surface and attach
it with double-sided tape or adhesive, for example.
oAttachment using housing is also possible.

Precautions when placing loads on the
unit
oMake sure the load is perpendicular to the surface to
which this unit is attached.
oApply 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 F2F
F is the correct load orientation
F1 is an eccentric inclined load
F2 is an eccentric load
oBe careful to avoid turning and twisting from lateral
loads. This could cause troubles like those described
in the previous item.
oBe 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.
oIf 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.
Electrical connection of load cell with
built-in TEDS
oConnect as shown in the illustration below. Incorrect
connections could result in inability to balance and
in errors occurring in the output voltage when loads
are applied.

TEDS
oThis unit has a built-in TEDS function.
The orange and green cores in the cable and the F and
G pins in the connector are wired for TEDS.
oThis unit does not support remote sensing.
oSince products that support remote sensing use the
same cables and connector pins as TEDS, be careful not
to try mistakenly to use these pins for remote sensing.
See the operation manuals of indicators and strain
amps that support remote sensing for how to connect
sensors with those units.
oThe shield is not connected to the main body of this
product. For this reason, if grounding is necessary because
of external noise, for example, arrange to ground the
shield to a part other than the body of this unit.
oSince the cable is directly connected to this unit, use
a specialized cable to increase the length. (Please
consult with us.)
oWhen conducting insulation resistance tests, limit them
to the red, black, blue and white cores. Do not apply to
the TEDS cores (orange and green).

TEDS

TEDS overview
TEDS (Transducer Electronic Data Sheet) is a memory chip
that can electronically read and write sensor-specific data.
The TEDS built into this unit has serial number, load cell rated
output and manufacturer name data recorded on it. By
connecting an indicator that supports TEDS, the TEDS data
of the connected load cell will be automatically read and
equivalent input calibration will be completed. (For details,
read the operation manual of the connected indicator.)
Refer to the connection diagrams in the “Electrical con-
nection of load cell with built-in TEDS” section as well as
the operation manual for the indicator being connected
for procedures to make connections.
TEAC indicators that support TEDS include the TD-01
Portable, TD-700T, TD-260T, TD-275T, TD-280T and TD-9000T.
For details, inquire at a shop that handles these products.
If not using the TEDS function, do not connect the orange
and green load cell cores.
Moreover, take measures to prevent the orange and green
cores from touching other terminals.
Data recorded in TEDS are tested values from calibration
conducted at room temperature during inspection before
shipping from our company.
Load cell output will be affected by the environmental
temperature where used, even when within the compen-
sated temperature range established in the specifications.
Although load cell output is calculated from the calibration
value saved in TEDS, when the environmental temperature
differs greatly from room temperature, the temperature
impacts increase on the zero point and the output. For
this reason, consideration of the effect on output voltage
is necessary. Output voltage changes will be within the
specification range as long as the unit is used at tempera-
tures within the specification range.
When using the TEDS function
This product’s cores for TEDS (orange and green) are
protected by a plastic cover as shown in the illustration.
This is to prevent miswiring and contact with other connec-
tors during use, for example, which could cause shorting.
To use the TEDS function, remove the tip of the plastic cover,
following the perforations, from the end of the cables. Then,
connect the TEDS cores (orange and green) to the indicator.
Refer to the“Electrical connection of load cell with built-in
TEDS”section for how to connect each wire.

When not using the TEDS function
If not using the TEDS function, remove the entire protective
plastic cover and cut off the TEDS cores (orange and green)
around where the plastic cover was attached to the cable.
If you use it without removing these cores, do not remove
the protective plastic or make other arrangements to prevent
the cores from touching other places.
Refer to the“Electrical connection of load cell with built-in
TEDS”section for how to connect each wire.

ATTENTION
Since the protective plastic and tag are not suitable for
the entire temperature range of this unit’s specifications,
do not expose them to high temperatures.
Handling after use
oWhen moving this unit while it is installed, take protective
measures to prevent it from being shaken or subjected
to excessive external forces.
oWhen storing it, keep it in a dry place where it will not
be exposed to water or oil, for example.
