HEC-HMS - use hydrograph instead of meteorologic model

I'm trying to model flow into a basin based on the user specified unit hydrograph I entered. The program is appearing to use the meteorlogic model instead which, for whatever reason, is a lot less than the Q generated per the hydrograph. How do I bypass the meteorlogic model?

We had this modeled in Pondpack, but the reviewing agency requires HEC-HMS and we havent used this before.

You need to link to that unit hydrograph table in the 'Meteorologic Models' options, select 'Precipitation' and you can select which time-series data you want to use.
