typically with and adjustable timing light you set the arrow to your spec, in the case 10 degrees and adjust the timing by moving the distributor do that the light on the harmonic reads at zero.

Sounds like you have some kind of adjustable light? I wouldn't know how to tell you to use it, as there are several different kinds most engines only have 20-30 degrees of marks for adjustment. Sounds like your light can be used for greater fine tune adjustments in the event of a higher lift cam. (Racing engines)

From your description, if I understand right, set your light to zero. This will give you an actual reading. Make sure engine is warm and attach to number one plug wire. Like you and others have mentioned 10° below/before top dead center. I'm not sure if there's any special things that need to be done on a TBI engine to check timing. But I doubt it.
