MTS Series 793 Tuning and Calibration
Force Sensor Calibration
Calibration Procedures 180
The slope and gain values are derived from, and are relative to, the output of the
load cell transducer as follows:
Where:
Compression is specified using the Neg Compression or Pos Compressive
entry box on the Calibration submenu or tab.
Tension is specified using the Neg Tension or Pos Tension entry box on the
Calibration submenu or tab.
Where:
Conditioner Output Voltage is typically 10 Vdc.
Excitation Voltage is specified using the Excitation entry box on the
Calibration submenu or tab.
Compression is specified using the Negative Compression or Positive
Compressive entry box on the Calibration submenu or tab.
mV/V Positive Tension
Calibration
Use the following procedure if your force transducer is set up so that a positive
output represents actuator retraction (tension).
1. Select mV/V Pos Tension for your calibration type.
Standalone FlexTest SE Controllers: Select Setup > Force > Calibration
> Cal Type > mV/V Pos Tension
Automated Controllers: Select mV/V Pos Tension for Cal Type on the
Calibration tab of the Inputs panel.
2. From the Calibration Data sheet for your force transducer enter the
following values on the Calibration submenu or tab:
Standalone FlexTest SE Controllers:
A. Enter the full scale force values in the Minimum and Maximum entry
boxes.
