So i bought an Oakton TDS Ecotestr today and the sales associate sold me 1500 calibration solution... so I when I tested the solution it was way off so I calibrated it to 1500. The solution was by Hanna with no indications as to which conversion .5 or .7 will read @1500. Did I just totally "uncalibrate" the tester?
