Description
Voltage output +
An output voltage of about 2 V for an
input of 1 mV/V is produced, which is
proportionate to the sensor output.
V-OUT is not isolated from the internal
circuit.
A negative output voltage for this
output is generated from B1.
Make sure that the cable you use is as
short as possible.
No connections. Do not use for relay
connections.
To clear a hold mode other than the
sample hold mode, set this signal to
ON.
To disable this signal, set Enable CLEAR
Signal (F2-8) to OFF.
This is the control signal for decision
outputs. Only while the control signal
is ON, decision outputs are enabled.
To disable the signal, set Enable JUDGE
Signal (F3-8) to OFF.
This is the start signal for a hold
mode. While the signal is ON, a hold
operation is performed.
To disable the signal, set Hold Mode
(F2-1) to 0.OFF (disable hold).
This signal digitally sets a reading to
zero. The function is enabled only
while both CAL Lock (F3-5) and Enable
Digital Zero (F3-1) are ON. When the
TD-260T is turned o, the digitally set
zero is cleared.
This is the common terminal for A5,
A6, A7, and A8. A photocoupler is used
to isolate signals from A5 to A9 and
the TD-260T internal circuit.

3-2-1. About sensor connection terminals
Sensor connection terminals (1, 2) can be used as either
remote sensing terminals or TEDS sensor data terminals. Before
connecting a sensor, you need to set Remote Sense/TEDS (F2-6)
to match the function you are going to use.
The initial setting is 0.Aut: TEDS auto-calibration (disable
remote sense). For detailed information, see the section 6-1-2.
“Remote Sense/TEDS.”
CAUTION
If you want to use a sensor with a 6-wire connection (for
remote sensing), set Remote Sense/TEDS (F2-6) to 2.rSE
(disable TEDS) before connecting the sensor.
3-2-2. About remote sense
The TD-260T uses a 6-wire connection (for remote sensing)
when calibrated at the factory.
Be aware that, if you connect a sensor by using 4 wires, and
then perform an equivalent input calibration, an error may
occur in a reading, resulting from the bridge voltage drop that
is proportionate to the length of the cable extended.
A 6-wire connection (for remote sensing) is excellent for
compensating for a voltage drop caused by the extension
of the cable length or voltage change due to changes in
temperature.
For applications of the TD-260T that may be exposed to
varying temperatures including the use of the device in an
outdoor installation system, or applications of the TD-260T
that require overall accuracy, we recommend the 6-wire
connection that includes remote sensing.

3-2-3. About bridge voltage (excitation voltage)
When you set the bridge voltage, make sure that the output
voltage from the sensor is relatively high, but that it does not
exceed the maximum excitation voltage specified on the
sensor test report at the same time.
Setting a voltage that exceeds the sensor's maximum
excitation voltage may cause the sensor to malfunction.
CAUTION
< If the sensor's maximum excitation voltage is lower than 10 V,
be sure to set Bridge Voltage (F2-5) to 2.5 before connecting
the sensor.
< For TEDS calibration, if the bridge voltage setting is higher
than the maximum excitation voltage recorded in the TEDS
memory when TEDS data is loaded, the bridge voltage
setting is automatically changed to a setting equal to or
lower than the maximum excitation voltage..
NOTE
< The initial setting is 2.5 V.

6. Calibration
Calibration shown in this document is the process of adjusting
parameters to determine a reading to be displayed on the
TD-260T when a strain gage sensor is connected. The following
three calibration methods are available in the TD-260T.
1. Equivalent input calibration
It is a simple calibration method that requires not the use
of an actual load, but only the key entry of the rated output
(mV/V) and rated capacity (value you want to display) of a
strain gage sensor. With this method, you can easily perform
a calibration if an actual load cannot be applied.
Examples:
In case of load, enter:
100 kN for the rated capacity and 2.001 mV/V for the
rated output
In case of pressure, enter:
10.00 MPa for the rated capacity and 2.002 mV/V for the
rated output
In case of torque, enter:
15.00 N · m for the rated capacity and 2.502 mV/V for the
rated output.
As shown above, enter values specied on a test report so
that the TD-260T automatically determines and displays a
gain.
Checking a sensor before calibration
Calibration cannot be done if the TD-260T displays an
unstable reading or error when you connect a sensor to
the TD-260T and then turn it on. In that case, set the TD260T to the static strain mode by performing Static Strain
Mode (F3-7), and then check a reading on the display again.
In this mode, the output from the sensor is displayed in
microstrains; the displayed output is 0 to ±6400.0 for the
input of 0 to ±3.2 mV/V.
CAUTION
The terminals (1 and 2) on the signal input/output terminal
block can be used as either remote sense terminals or
the TEDS sensor data terminals. Before connecting a
sensor, you need to change the setting for Remote Sense/
TEDS (F2-6) to match the function you are going to use.
The initial setting is 0.Aut: TEDS auto-calibration (disable
remote sense). For detailed information, see the section 6-1-
2. “Remote Sense/TEDS.”
2. Actual load calibration
It is a calibration method that requires you apply an actual
load to a strain gage sensor and then measure it.
For accurate calibration, which minimizes errors, you need
to apply a load that is close to the sensor's maximum
measurable value.
3. TEDS calibration
It is a calibration method that uses data on the rated output
(mV/V) and rated capacity of a strain gage sensor both
stored in the TEDS memory.
The TEDS memory is available in 1-kilobit and 4-kilobit sizes.
Note that the TD-260T supports the 4-kilobit memory only.
The test report included with a strain gage sensor provides the following information.
Rated Capacity: load, atomospheric pressure, etc. (Unit: kN, Mpa, etc.)
Rated output: voltage (Unit: mV/V)
Nonlinearity: %R.O
Hysteresis: %R.O
Maximum Excitation Voltage: V (bridge voltage)
Input Terminal Resistance:
Output Terminal Resistance:
Zero Balance: x10-6 strain (microstrain)
< Data required for equivalent input calibration are rated capacity and rated output.
