UPS just droped off my BRS order which had an RO/DI unit and a TDS meter. I have the unit hooked up now and I am waiting for it to produce. I checked the rodi water that im buying from my LFS and the TDS is 002 PPM. My tap water is 569 PPM. I tested my tank water and the display comes up - - -. Does that mean that the TDS in my tank is 0? I would think if it is 0 then the unit would say 000. Thanks in advance.
P.S When I first turn the meter on it reads 000.
