How to perform an LVDT calibration with PLX-HotStage

This operation takes about 90 seconds. It correlates the signal of the LVDT with the crosshead displacement. The procedure is as follows:

Position the crosshead and place the LVDT and working distances calibration sample (provided by PLX) on the platen. The LVDT and working distances calibration sample is simply a flat piece of metal with minimal surface roughness and tilt – the user could use another suitably prepared metallic sample if they misplace the PLX provided sample.

1. Go to Tools > Calibrate > LVDT. When ready, click ‘Start’.
2. A dialogue box appears. Ensure that there is no sample in the HotPIP platen and click ‘OK’.
3. The indenter housing moves downward until the crosshead touches the LVDT.
4. The indenter housing moves downward at a fixed (slow) speed, periodically recording the LVDT output signal.
5. The indenter housing is retracted so that the crosshead is clear of the LVDT.
6. A dialogue box appears. The procedure is then terminated by clicking ‘Finish’.
7. Retrieve the calibration sample or leave it in place if moving on to the Working Distances calibration.
