Open the Controller Station
To open the controller station:
1. Start the Station Manager application.
2. In the Open Station window, select a a configuration file.
3. Click Open to open the configuration file.
Prepare Controller Station for Operation
The following procedure provides a basic outline of the steps required to prepare the controller station for
specimen installation and test operation.
1. Make sure all sensors are properly calibrated.
2. Make sure the test channels are properly tuned.
3. Make sure the polarity of the sensor signals are properly set for the test.
4. Set up error detectors.
5. Set up limit detectors.
6. After the Series 793 Station Manager application is properly set up for operation, make sure the user
access level is not set to Configuration.
The test control application will not allow you to connect to a station when the Station Manager application
user access level is set to Configuration.
Crack Opening Displacement (COD) Sensor
Signal Polarity
The following templates require you to invert the polarity of the Crack Opening Displacement (COD) clip
gage sensor signal in the Series 793 Station Manager application when used:
• ASTM E 1820 JIC template with an SE(B) specimen
• ASTM E1290 CTOD template with an SE(B) specimen
Note:
When running other template and specimen combinations, make sure that the COD sensor signal
is set to Normal in the Station Manager application.
You can manually set the signal polarity in each instance, or you can create separate station configuration
and parameter sets for the different signal polarities for use with the corresponding template and specimens.
