    That usually means its broke or not calibrated? Does it show "err" when you place it in water. Do not not put it in salt water, that ruined one of mine. It may need to be calibrated as well, do you have calibration fluid?

    What does it do when you place it in "non" salt water? Sounds like it may need to be returned.

    It might just give "err" when the probes are dry. Try using it. Then try reading up on how to calibrate it.

    I would see about getting the RO down to 5 or below if you can...18 will burn through DI resin pretty fast....

    I used to get 20 from the RO and changed my filters and types of filters and now I get 3 from RO. I now change DI resin about 1/3 of the rate before...
    You have 1 DI cartridge or 2?

    Hope that helps
