The closest you could obtain would be a radionics device, which is barely any different from other divination methods like pendulum dowsing. If you intended to obtain a five digit readout of someone's FRV, then a five-dial radionics box would let you do that. But there is an element of subjectivity there that only becomes objective after much experience and practice. In the end you'll discover that your intuitive reading of a person's vibe matches the numerical readout, and that the latter is just a more detailed version of what you already know.
But if you want something more objective, like something that operates on batteries and gives you an instant digital readout of the vibrational field of anyone it is held up to, that is black ops military technology. It would work via some very exotic quantum mechanical and scalar physics principles. I suspect that black helicopters are outfitted with such devices, that these are also used just like metal detectors at entranceways to certain government and military facilities. My guess is that this technology measures the gravitational resonance spectrum of your etheric body.
Also, do you just temporarily lower your vibes when you cry or think about crappy stuff? Or do you have an overall lower value when you lead a life that involves lower vibrational emotions, as in reading and contemplating heavy stuff for most of the day, which is sometimes upsetting?
Good question... FRV is a whole spectrum of vibrational resonances, and the longer you have resonated at some particular level the larger its amplitude and the more inertia it has to changing. So think of it like a reverb-echo that lingers after you hit a key on a piano, one where the longer and louder you keep hitting the key, the louder and more prolonged the echo. Each key hit is an emotional and mental impression within you. So as you go through life, the echo becomes a composite of what keys are played. So if you are always playing the lower keys, the echo will have a low sound. And if you hit the upper keys once or twice only, their contribution to the echo fades out soon. But likewise, if you have a medium or high echo, and momentarily hit the lower keys, while it does temporarily lower the average frequency of the echo, the fact that the medium and higher frequencies have more permanence means that temporarily going lower does not have a permanent effect.
In my experience, it takes about three days of maintaining a particular mindset or emotional attitude before reality starts responding in full force with synchronistic experiences that match and reinforce those. And sleep seems to reset things somewhat, so it is better to be in a funk before going to sleep, than to enter into one in the morning because what you do in the morning initiates momentum for the rest of the day. But if you have a bad attitude for several days, watch out. Some people have it for most of their lives and the results are predictable.
Acquiring fringe knowledge is like digging for diamonds in a mine field.
