So, what kind of instrument do you measure the multiverse where time does not exist and every thing occupies the same space continually?

You misunderstand the theory of the multiverse.
Infinite multiverse branch off every instant from ours and do not occupy the same space. They are different universes. theoretically.
How do I measure them? we are still ill-equipped to see the underlying quantum reality. But, there was also a time when we did not have o-scopes and millimeters and spectrum analyzers to measure the movements of electrons either.
here are four ways to "see' and understand the multiverse theory..
1 The wave function
In the traditional Copenhagen interpretation of quantum mechanics, the wave function is said to "collapse" when the measurement is taken, but it isn't clear how this happens. (Schrödinger's famous cat, neither alive nor dead until someone looks inside its box, illustrates this.) In the multiverse, the wave function never collapses: rather, it describes the property across multiple universes. In this universe, the atom's spin is up; in another universe, it's down.
2 Wave-particle duality
In the landmark experiment( www.newscientist.com ), photons are were sent one at a time towards a pair of -----, with a phosphorescent screen behind them. Take a measurement at either ----, and you'll register individual photons passing particle-like through one or the other. But leave the apparatus alone, and an interference pattern will build up on the screen, as if each photon had passed through both ----- simultaneously and diffracted at each, like a classical wave.
3 Quantum computing
Though quantum computers are in their infancy, they are in theory incredibly powerful, capable of solving complex problems far faster than any ordinary computer. In the Copenhagen interpretation, ( this is because the computer is working with entangled "qubits" which can take many more states than the binary states available to the "bits" used by classical computers. In the multiverse interpretation, it's because it conducts the necessary calculations in many universes at once.
4 Quantum Russian roulette
This amounts to playing the role of Schrödinger's cat. You'll need a gun whose firing is controlled by a quantum property, such as an atom's spin, which has two possible states when measured. If the Copenhagen interpretation is right, you have the familiar 50-50 odds of survival. The more times you "play", the less likely you are to survive.
If the multiverse is real, on the other hand, there always will be a universe in which "you" are alive, no matter how long you play. What's more, you might always end up in it, thanks to the exalted status of the "observer" in quantum mechanics. You would just hear a series of clicks as the gun failed to fire every time and realise you're immortal. But be warned: even if you can get hold of a quantum gun, physicists have long argued about how this most decisive of experiments would actually work out.
