I'm confused....here are the directions for initial calibration....
Select a standard(between 200ppm and 1990 ppm) close to test solution value. Switch on the tester and dip sensor into into standard solution. Once reading stabilizes, press up or down button to adjust displayed value according to the standard solution value.
1:Select a standard(between 200ppm and 1990 ppm) close to test solution.
....is this my water???
2:Switch on the tester and dip sensor into into standard solution. Once reading stabilizes, press up or down button to adjust displayed value according to the standard solution value.
Lets just say that my tap water is 200ppm......when they say to press up or down button to adjust displayed value according to the standard solution value....do they intend for me to bring the digital readout to zero....I'm so lost
