3. Connections
3-2. Connecting strain gage sensor
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.

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 specified on a test report so that the TD-260T automatically determines and displays a gain.
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.

Calibration

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 6-12. “Remote Sense/TEDS.”

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) Linearity: %R.O Hysteresis: %R.O Safe excitation voltage (maximum): 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.
< TEDS sensor has the above data saved in its internal memory.

7-2. Hysteresis
Using this function, You can buffer the set points at which the HH, HI, LO, and LL decision outputs switch off. If fluctuations in the reading occur near each comparative point, the corresponding decision output switches on and off, which is a phenomenon called “chattering.” You can prevent the output from chattering by setting a hysteresis value. Hysteresis for the HH and HI values is enabled when the reading decreases, and hysteresis for the LL and LO values is enabled when the reading increases, as shown below.

7-6. Motion detection

You can set parameters used for detecting stability. If the difference between the currently displayed reading and the reading that was displayed 100 milliseconds ago is equal to or lower than the bandwidth you set, and then the state remains unchanged for more than the length of set time, the TD-260T determines that the currently displayed reading is stable. The motion detection setting is closely related to the comparison mode setting. For detailed information, see the section 7-4. “Comparison Mode.” If the displayed reading is determined as stable, the P.C. (stable) signal from the optional BCD output is turned on and the stable output for the RS-232C read status command is set to ON.

12. D/A Converter (TD-260T AC(D/A) / TD-260T DC(D/A) )

The D/A output circuit is isolated from the TD-260T internal circuit. The analog output ranges are 0 to ± 10 V in voltage and 4 to 20 mA in current. Using the D/A zero and D/A full-scale functions, you can respectively obtain analog output zero (0 V, 4 mA) and full scale (±10 V, 20 mA) for any digital value you set. Notice that the output current for the output voltage 0 V is 4 mA and the output current for the output voltage 10 V is 20 mA. You cannot set a value for the output current and output voltage separately when you change the zero point or full scale setting. Resolution is ±1 per 10000 for 0 to ±10 V, and the conversion rate is 100 times per second. The D/A converter has an overrange capability of about ±10 % on the output.

14. About TEDS

Connecting a sensor that conforms to IEEE1451.4 (Transducer Electronic Data Sheet (TEDS)) to the TD-260T, you can load the rated output values that are saved on the sensor into the TD260T and use the values for calibration with the TD-260T. You can also use the TD-260T to save on your TEDS sensor values that are used for calibration with the TD-260T or to restore the TEDS sensor’s factory settings. TEDS memory is available in 1-kilobit and 4-kilobit sizes. Note that the TD-260T supports the 4-kilobit memory only.
