This page describes the status of the fishing rods and provides characterization information measured at the time of assembly.

It's important to bear in mind that the reported range of the stepper motor in number of steps is not expected to be accurate and it's useful only as a guideline:

With respecto to the LVDT range limits, those may change with temperature.
