Does Fisher Information quantify only the precision of the instrument?

I had asked a question recently. There were some comments by someone named Solar Mike.

On repeatedly asking him/her on elaborating what he meant, there was no proper reply. I realized most of his answers are similar, on physics.stackexchange.

    $\begingroup$ That's really an unfortunate mix up there. It seems Solar Mike thought you were asking about the information in Fisher's catalog (Fisher is a manufacturer of precision measurement instruments). If you read it in that way, then the question isn't very good, possibly explaining the downvote. $\endgroup$ – knzhou Jul 16 at 14:03
  • $\begingroup$ To help avoid this kind of mix up, it's useful to link to, e.g. Wikipedia on any terms that don't have an unambiguous definition. $\endgroup$ – knzhou Jul 16 at 14:03

    $\begingroup$ As Jon pointed out, it's not really clear what you're asking here. I've put the question on hold until that gets clarified. $\endgroup$ – David Z Jul 16 at 18:15
  • $\begingroup$ @knzhou I think that could be a goof up. He had been insisting again and again on calibrating the instrument. I thought that Fisher Information is well known in the Physics community, looking at other questions on physics.stackexchange. I will include sources and definitions henceforth. $\endgroup$ – Chetan Waghela Jul 17 at 10:26
