Belt and motor manufacturers recommend that one not do so but we all know it's done all the time. The following link has some guidelines that are useful background knowledge.

The upshot is the measurement is the force required to deflect the belt the proper distance at the midpoint of the span. The nominal deflection is the span/64 and there's a table of force vs motor size and rpm. Roughly for 1 hp motor the recommended force is 1-2 lb from 1000 to 3500 rpm.
The tension should be no greater than that required to prevent slip. One way to observe slip if one has a timing light is to mark a spot on the belt and use the light to observe it during operation using the driver pulley to synchronize the light.
Not knowing anything about the application, anything more specific is difficult.
