FPS testers

With the Chronograph it is possible to measure your FPS/Joule value which can be measured with various weights of bb's?

The weight can be set in the Chrono but keep in mind that in the Netherlands we only measure with 0.30gr bb's and look at what the Joule value is.
FPS is no longer relevant.
