Idiots guide to checking rad fan speeds

So as above,
I have a 53 plate zt190 with 86K on the clock with the early 3 speed rad fan which when I first got a couple of years ago was T4'd by Trikey and all 3 speeds were working, now I'm not sure if the low speed is, If Trikey was not away on his hols I would arrange for a T4 session to be absolutely certain,
can someone explain to me an Idiot proof way to see if the low speed has failed so that if I need to I can get it sorted out, there is some urgency as I will be doing a Monte Carlo run on the 16th of August and I don't fancy running without low speed, on the other hand I don't want to spend money if it's all in my head and I don't have to
