TDS checker may need calibration occasionally. Maybe bring water sample to LFS with meter and have them compare it to theirs.

What I did was check it in distilled water. Research showed it should read between 0 and 7. It read 4.TDS checker may need calibration occasionally. Maybe bring water sample to LFS with meter and have them compare it to theirs.

Vertical mount is best for DI, and I would definitely not trust distilled water to be pure enough for calibration.
