How are you testing and how clean is your meter?
Get yourself a squeaky clean glass drinking water glass with absolutely no water spots or detergent residues on it. Fill it with DI water and clean the heck out of your meter probe, swish it around real well and do this a couple of times.
Fill the glass with tap water and test the TDS, triple rinse both the glass and TDS meter with DI water. Next fill it with RO only water before the DI and record that TDS reading, again triple rinse with DI water. Finally fill it with DI water and get your final reading and do a good final rinse of both the meter and glass and store the glass upside down somewhere safe for next time. Replace the cap on the meter and keep it clean also, never try to test saltwater as its way beyond the meters range and will contaminate the probe.
If things are working as they should you should be seeing a 90 to 98% reduction in TDS between the tap water and RO only and 0TDS from the DI. If not you may want to buy some bottled distilled water and TDS calibration solution to check the meters calibration.

If you rinsed it well with DI afterwards its probably OK but if you let it sit it may need more cleaning than just rinsing. A dip and swish in white vinegar may be in order.
What are your readings? What kind, size and type of DI do you have?

hey azdesertrat thanks for helping me the other day about the order for the filters... Ill try and clean it off and do some readings in the morning....hope that it works..... before I put the DI on it read 006 but then again if my TDS meter is messed up that could be wrong.... I'll let you know if the cleaning helps.....
