someter in 8800/ElectroPuls console. As part of the manual calibration, set the
transducer type to Strain (Calibration wizard > Transducer details screen). For more
details refer to “Using the AVE2 with an 8800T or 8800D Controller” in the Console
online help.
The strain transducers for the video extensometer are now calibrated.
Calibrate using touch-enabled user interface
You should calibrate the extensometer upon initial start up and also after you change
anything in the setup, such as changing a lens or changing the position of the AVE2.
This procedure requires a calibration bar. If you are using a 6mm lens, then two
calibration bars are required.
1. Start the video extensometer by pressing the power button on the front. The light bar
illuminates.
2. If it is not already open, launch the Instron Video Extensometer application. The video
extensometer dialog displays.
3. Position the crosshead and the video extensometer as required for the specimens
that will be tested.
4. For all lenses except the 6mm lens:
a Install the calibration bar in the upper grip only, making sure that the matrix of
dots faces towards the extensometer.
b If necessary, remove the lower grip to avoid damage to the calibration bar.
c Move the crosshead so that the image of the calibration bar fills the field of view.
5. If you are using the 6mm lens, you must use two calibration bars to accommodate
the large field of view, as follows:
a Install one calibration bar in the upper grip, making sure that the matrix of dots
faces towards the extensometer.
b Install one calibration bar in the lower grip, making sure that the matrix of dots
faces towards the extensometer.
c Move the crosshead so that the upper bar is near the top of the field of view and
the bottom bar is near the bottom of the field of view. Make sure, however, that
the bottom bar is at least 50mm above the bottom of the field of view to optimize
accuracy.
6. Select Calibration.
The dialog moves to the Calibration screen.
7. Remove the red lens cover (AVE2 only; there is no lens cover on the SVE2) by gently
pulling it away from the lens.
