Checking A/F ratios

I'm having a few problems with my 88 and one of the PCA tech guys said to get my A/F ratios checked. My wrench doesn't have a dyno and to check the ratios he will stick some kind of probe in one of the two tail pipes. He said it's like what the emission testing station does. Is this probe mobile and he'll drive around with it hooked up or will the car just sit while he revs the engine? I'm just trying to look into what he'll be doing so I have a better understanding before I bring him the car.
