No way to measure initial forces on board power-up

[PeterBowman]

There seems to be an implicit set-to-zero routine as soon as the board receives data from the sensor for the first time. That is, I'm seeing zero forces/torques despite having a payload attached to the sensor. Do not confuse that with the zero-offsets ioctl command which allows to force said set-to-zero operation at any time (I presume the "Only filtered reads and zero offsets setup are supported." line in the README.md refers to this).

Per 5963B - External Digital Electronics (at https://www.jr3.com/resources/product-manuals, also uploaded to https://github.com/roboticslab-uc3m/datasheets-and-manuals), section Offset Adjustment:

The offset adjustments set the system zero point output with no load applied. The zero load output may change by up to 20% of full scale when the sensor mounting bolts are tightened. Attachment of your apparatus or structural components will also change the output due to their weight.

Typically, the output is set for zero with no applied load, but specific uses may require a setting other than zero.

There are two sets of offset adjustments, the “8 channel offsets” and the “6 channel offsets.” In most situations only the 6 channel offset adjustment will need adjustment once the system has been adjusted after installation.
