Product Support: www.instron.com
When the device is connected to the testing system, the automatic extensometer icon
appears in the Bluehill
®
console. The icon will be grayed at first.
The following procedure lists the steps required to initialize the AutoX. More detail on
individual options within the Transducer Settings dialog can be found in the Bluehill
Reference Help online documentation.
1. Click at the top of the screen in the system settings area of the console to
open the Transducer Settings dialog for the AutoX.
2. In the first tab, select a transducer configuration in the
Transducer configuration
field. The default is Strain 1.
3. Enter a value in the
Target carriage position
field to change the lower carriage (or
upper carriage) location.
The default target carriage position is 150mm for the lower carriage with the
reference stop set to 100mm.
4. Select the type of gauge length:
Manual
or one of the proportional gauge length
settings: or .
5. For Manual gauge length, enter a value in the
Target gauge length
field to change
the gauge length. The default value is 25mm.
6. Verify that all the target settings are between the upper and lower fixtures that grip
the specimen and that no obstructions will prevent movement of the carriages
during a test.
7. Click
Initialize
. A second dialog displays with the reference stop settings in which
you select the upper or lower stop as the reference stop and enter the position of the
selected reference stop. When you click
OK
, the system moves the target carriage
to the specified reference stop on the extensometer (upper or lower) and then
moves both carriages to the target settings specified in the Transducer settings
dialog. This completes the initialization of the automatic extensometer.
After initialization, the automatic extensometer icon in the console settings area
changes to show that the transducer is available. The extensometer is now enabled
and ready for testing.
8. Click
Move
to relocate the carriages to the new settings.
The system moves the lower carriage (or upper carriage) to the target carriage
position and then moves the other carriage to the distance specified as the target
gauge length.
