Power Meters / Powermeters (SRM, Powertap, Quarq, Ergomo, Vector, Stages, power2max, P2M, 4iii, InPower, Cinch)

so i want to get a benchmark for how much power I can generate, so i can test myself throughout the season, I have access to a wattbike for whenever i need it, what is the best measurement/test to do to have as a benchmark?

My tri coach has suggested a CP30 test, but the watt bike I have access to doesn't seem to have this test pre-loaded on to it from looking at the manuals, and ideally the test would be on the machine so i can just get on it and pedal...

Options for testing FTP in increasing levels of accuracy.
Whatever method you choose, repeatability is key.
