||
| 11 | |||
| 12 | On the instrument host of the instrument, a TEM host that uses Tecnai class, for example, you can launch python command line window and try to create an instance of the instrument and then call a function such as getMagnifications in that like this: |
||
| 13 | |||
| 14 | <pre> |
||
| 15 | import pyscope.registry |
||
| 16 | 6 | Neil Voss | s = pyscope.registry.getClass('jeol1230')() |
| 17 | 2 | Neil Voss | s.getMagnifications() |
