Out of range error

Dear Colleagues,
I'm using a Shimadzu LC-9A with UV detector SPD-6AV. I'm trying to use an wavelenght of 202 nm but when I adjust zero I receive the following message: "Input level is out of range". Can somebody help me??
Thanks

I'm guessing that you're seeing this in your Data System (please elaborate on that) - probably because your baseline is unstable and is drifting below what the data system's analog input can track.

Also - have a look at your Aux Range setting. Try it at 1 (or more) AU/V.
