MTS Series 793 - Manual (Page 199)

• Basic TEDS sensor information (Series 494 hardware only): sensor manufacturer, model, and serial
number.
Calibration Data for Replacement Sensors
If you replace or add a sensor, you must perform one of the following procedures before using the system:
• If you have a sensor file that contains the sensor calibration data for the new sensor, use the Station Setup
window to assign that sensor file to that sensor input.
• If you have a calibration report from a lab-standard calibration, use the Sensor File Editor to create a
sensor file that contains the calibration data. You can then use the Station Setup window to assign the
sensor file to the sensor input. You could also enter the data and save it in a parameter set.
• If calibration data is not available, you must calibrate the new sensor against a lab standard. You can then
use the Sensor File Editor to enter calibration data and create a sensor file. You can then use the Station
Setup window to assign the sensor file to the sensor input.
Calibration Tab
This tab defines the calibration values that a conditioner applies to its sensor. This tab’s controls vary with
the type of conditioner used.
Access

Calibration Tab
Description Item
Sets the Current Range minimum and maximum values and the feedback
signal’s display units. Fullscale Min/Max
Ranges can be asymmetrical if the Max is greater than or equal to zero and
the Min is less than or equal to zero.
Sets the polarity of the feedback signal to change how the actuator responds
to commands: Polarity
Normal - A positive command can extend or retract the actuator, depending
on system conventions.
Invert - Reverses the actuator’s Normal response.
Sets the encoder resolution value, typically the value specified in
documentation supplied with the sensor. Resolution
(Encoders only)
For Series 793 applications, an encoder yields four times its count rating per
revolution. For example, if you use an encoder that is rated at 120 counts per
revolution, the actual count per revolution would be 480. In this case, a
resolution of 0.5 would yield 240 counts.
If you want to use units different than those supplied in the sensor
documentation, enter the full scale and resolution in the supplied units first,
and then switch to the desired full-scale units. The unit conversion will be
calculated automatically.
