Description

“Remove the protective cap. Turn the TDS meter on. The ON/OFF switch is located on the panel. Immerse the meter into the water/solution up to the maximum immersion level (2 inch). Lightly stir the meter to dislodge any air bubbles. Wait until the display stabilizes. Once the reading stabilizes (approx. 10 seconds), press the HOLD button to view the reading out of the water. If the meter displays a flashing x10 symbol, multiply the reading by 10. After usage, shake off any excess water from your meter. Replace the cap.”
