I haven't done it on mine, but here are the instructions; http://www.tdsmeter.com/calibration_maintenance.html<a href=showthread.php?s=&postid=14066722#post14066722 target=_blank>Originally posted</a> by prostaff
I have the same meter and it read 28 tds raw water and 0 after my spectrapure 7 stage system producing 200gals/day. It is still giving me a zero reading 5 years later and several thousand gallons later. I figured it is lasting this long due to the relatively low amount of TDS going in but I am starting to worry. Do you guys know how to calibrate this meter? I know it says calibrate with NaCl solution on the back but does anyone know how to mix it??
