Extensometer Calibration
MTS Series 793 Tuning and Calibration Calibration Procedures 201
Task 4 Gain/Delta K Calibration
If you are using Gain/Delta K for your calibration type, complete the following
procedure. If not, complete Task 5 Gain/Linearization Calibration on page
204.
Calibration setup 1. Ensure that the extensometer is properly attached to the calibrator frame
using the associated installation drawings and calibrator fixtures.
2. Set an initial transducer excitation voltage.
Standalone FlexTest SE Controllers:
Select Setup > Strain > Calibration > Cal Type > Gain/Delta K >
Excitation (peak)
Set the Excitation (peak) voltage value (typically 5-8 volts).
Automated Controllers:
A. In the Station Setup window’s navigation pane, locate and select the
Channels resource providing the strain feedback signal.
B. In the Station Setup window, click .
C. In the Inputs panel, click the Calibration tab.
D. Set Type to Gain/Delta-K.
E. Set Excitation (peak) voltage value (typically 5-8 volts).
3. If the extensometer uses a zero pin, remove the zero pin now.
4. Monitor the extensometer’s amplified output (strain).
Note Before clicking Auto Zero, ensure that any offsets due to Auto Offset
and Manual Offset actions are eliminated.
