I think your display is reading a bit high. From your other thread, you mentioned you have a 10K gal pool. You also mentioned that you found 7 40# bags in the trash. That's 280# of salt, and that should have brought your salt level up to 3300 or so. Of course, that's assuming that all the bags that he used ended up in the trash at your house.

What is your unit supposed to run at? Most are 3200, so you aren't far off (technically) from that number.
