Salt Reading Error?

Seems most SWG digital salt readings tend to bounce around a bit...but not from 3000ppm down to where your low readings were. Take a water sample to a reputable pool store and have it tested. I'll bet your readings will be way high because of the added salt you put in the pool. I have been told that the only way salt levels will go down in a pool is by dilution. That could happen by getting a lot of rain water in the pool.....or by adding fresh water to your pool with a hose. Other than that the salt levels will stay the same.

Me thinks you better have your installer check out the system. It's possible that if your cell is scaled up or some blockage on the cell, it will give you a false reading. The cell is attached with unions so you can remove it and visually inspect it. If you're able to see the blade (you may try a flash light on the opposite end, or if there there is some blockage on the plastic grid infront of the cell, these can also indicate no salt.
Or it may be something else worse.
First things first though and it's worth checking the easier stuff first.
