PQ range EnVision multi label reader

I have to figure out a range to cover PQ for a plate reader. The facility is a contract location so their assays are customer based. I have been asked to run liquid samples for the PQ and would like to know if anyone has experience determining the appropriate range for fluorescence and absorption of this instrument. The specs are available but was looking for real world operation instead of aiming for a spec. Much Appreciated, Cheers!
