Divergence Meter

The Divergence Meter is a device brought back from 2036 by Suzuha.

It is a modified Nixie Tube clock that uses an unknown method to determine the "Divergence Value" of the current world line in relation to the absolute world line of 0%.

The Divergence Meter is used to calculate what Attractor Field the universe is currently in. Throughout the course of the storyline Okabe tries to break the 1% barrier in order to escape from the Alpha range, using the meter as a reference each time.

It was originally in Okabe's possession, when he died it was passed on to Daru, and in turn was passed on to Suzuha. Suzuha then left it behind for Okabe, completing the cycle and showing that the Divergence Meter invented itself.

It has some limitations in that it cannot display certain values, this is shown in the Omega Attractor Field in which the first digit cannot be displayed due to the divergence being negative.
