IMPORTANT SAFETY INSTRUCTIONSV 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

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
oo 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 withcorrosive gases should be avoided.
oo Be careful to prevent water, oil and other substancesfrom getting on the unit.

ATTENTION
oo 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 diagonallines at the top and tighten the screw or nut.
WrenchJig for tightening(commercially-available)

oo Avoid use in conditions where condensation could occur.
oo Connect cores to the load cell after discharging (eliminating) static electricity from your body.
oo If the surrounding temperature changes suddenly, thevalues 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.)oo Conduct load calibrations periodically.

Installation procedures
Insert a screw into the screw hole in the center part of theload 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 shownin “Recommended tightening torques when attaching toload jigs and surfaces” below.

selection, for example.

Wrench(commercially-available)
Jig for tightening

Hold the rod
end in placeoo In the same way, when attaching a rod end or base,for example, to the screw/bolt area on the bottomof the load cell, use the included jig to hold the area
shown with diagonal lines at the bottom and tighten
the screw or nut.

Wrench(commerciallyavailable)

oo When tightening the screw or nut attached to the loadcell, 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.

oo When removing it, follow the attachment proceduresin reverse order. On the top or the bottom side of theload cell that has 14mm width across flats, the side thathas 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.
oo Attach a load button, for example, when using withcompression.
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
to apply torque that exceeds the tightening torqueshown in the table.
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.
oo When using with a tensile load, attach a rod end or
tensile load adapter.
oo When attaching a rod end to a load cell, use a nut toprevent loosening. When tightening this nut for preventing loosening, secure the rod end. Do not tighten
the nut by securing the load cell. If twisting force isapplied between it and the central screw part, the loadcell could be damaged.

Nut

Do not holdthe load cellin place.

oo Always use screws/bolts that are suitable for the rated
capacity when attaching a base plate or tensile load
adapter, for example, to the load cell. Moreover, tighten
all of the attachment screws/bolts evenly.

Precautions when placing loads on the unit
oo Make sure the load is perpendicular to the surface towhich this unit is attached.
oo Place the load so that it is centered on the center of theunit. If the load is not centered (eccentric load), twisting,for example, and measurement errors could occur. This
could even result in damage.
F1

oo If the load receiving area is contacted by something thatis 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 differenceceases to exist before measuring.

Electrical connection of load celloo Connect 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.

because of external noise or another issue, arrange toground the shield to a part other than the body of thisunit, for example.
oo Since the cable is directly connected to this unit, use
a specialized cable to increase the length. (Please
consult with us.)oo When conducting insulation resistance tests, limit themto the red, black, blue and white cores. Do not apply to
the TEDS cores (orange and green).

Refer to the connection diagrams in “Electrical connectionof load cell” as well as the operation manual for the indicator
being connected for procedures to make connections.
TEAC indicators and signal conditioners that support TEDS
include the TD-01 Portable, TD-700T, TD-260T, TD-9000T
and TD-SC1. For details, inquire at the retailer where youpurchased the unit.
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 compensated 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 thespecification range as long as the unit is used at temperatures within the specification range.

When using the TEDS function
This product’s cores for TEDS (orange and green) areprotected by a plastic cover as shown in the illustration.
This is to prevent miswiring and contact with other connectors 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 “Electrical connection of load cell” for how toconnect each core.

TEDS overview
TEDS (Transducer Electronic Data Sheet) is a memory chipthat 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 dataof the connected load cell will be automatically read andequivalent input calibration will be completed. (For details,
read the operation manual of the connected indicator.)

Handling after use
oo When moving this unit while it is attached, take protective
measures to prevent it from being shaken or subjected
to excessive external forces.

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 preventthe cores from touching other places.
Refer to “Electrical connection of load cell” for how toconnect each core.
Note about the tag attached to the TEDS cable

ATTENTION
Since the protective plastic and tag are not suitable forthe entire temperature range of this unit's specifications,do not expose them to high temperatures.

oo When storing it, keep it in a dry place where it will not
be exposed to water or oil, for example.
