Ok Received my dual stage DI add on to my RO and got everything hooked up. Let it run for a bit and decided Id check the TDS meter to see if I had managed to reach that magical 0 or 1 reading and all I get is ERR.
 
I did move the TDS meter probe to after the DI unit. but even my in reading is showing ERR.
 
DO I have a bad unit. Possible issue wit hthe probes? should I pull the probes out and see if theres a buildup or anyhting? If so How the heck do I get them out? They arrived all in one.
 
The TDS meter I have is the HM Digital dual in-line TDS meter.
