Ok remember I accept that I know nothing. You ro/di unit will only take out a percentage of your impurities in your tap water. Get some distilled water at the supper market and test it. If it tests zero leave your meter as it is

Wow, your tap water is 038?
I guess my city water really sucks (298 to 300).
My RO/DI reads 0.
That's why I bought a RO/DI unity.

You stated you tested your "already made RO/DI" is this something you purchased or something you made yourself?
If its your RO/DI unit I would change your filters, it should read 0 and no more than 3.
If its store bought RO/DI water take it back and tell them to check their filters, and take your TDS meter with you to show them.

It's made here...I was thinking that it was time to change the filter, but was waiting for the meter to arrive...I'll change it tonight and retest the water.

Ok let me just give my uneducated opinion here. If you check your RO unite and it states that it takes out 100 % of DTS then you will read zero if it does not then your reading will be a percentage of your total TDS in your tap water that it filters

You know I buy these dumb things to make life easier....why is it always the opposite for me

I do not have a big fancy ro/di water purifier (YET) but what I have it 100% better than what i had before...which was nothing...
I changed the filter and retested and it said 2....so that has got to be better than 38 right?

Forgive me if I'm hijacking your thread meowzer but I must ask florida joe a question.
What is DTS stand for? Is it the dissolved solids?
Anyway a TDS meter is measuring the electrical conductivity of the materials dissolved in a given volume of water. So it is only measuring whats there, isn't it?
I mean your filters are removing any minerals, salts, metals, cations or anions dissolved in the water right?Whatever is left is what the TDS meter is reading.
Ow, my head hurts now. Am I on the right track, florida joe?
Oh, meowzer, 2 is definitely better than 38.

Ok lets separate your TDS meter from your RO unit. If your RO unite is filtering out 95 percent of the DTS in your water. You are still left with 5 percent. Now depending on your DTS present in your tap water that 5 percent can be any number. So you have to test your tap water take 95 percent away from that. If the number you are left with is the number you get after your RO filtration you have the best you can hope for. Then again what do I know I mean this with all due respect to all involved

Do you have an RO/DI? Or just RO?
Some people accept higher values, but if all the different components of the RO/DI were working up to full capacity, your number should be zero. I start gathering up supplies as soon as mine hits 1. Just an RO unit is different and is based on what your filter is rated at. If your filter is 95%... you're within range. If it's 98%, you need to change some some filters... if you're Ro?DI, something is not filtering to capacity.
How the heck is your tapwater 38... is it city water? Well water? Fresh Hawaiian springs in untouchable parts of the Islands? Glacier water? Mine is sometimes 600+ *cries*
