'"Dissolved solids" refer to any minerals, salts, metals, cations or anions dissolved in water. This includes anything present in water other than the pure water (H20) molecule and suspended solids. Suspended solids are any particles/substances that are neither dissolved nor settled in the water, such as wood pulp.'

Darn. I just recalibrated twice with 800 ppm calibration fluid, adjusting for current temperature, and I'm now getting a TDS reading of 2 for tap water.
