Taking TDS Measurements
• 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”).
• 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.

Taking Temperature Measurements
• Once the meter is on, the temperature function can be used at any time, in or out of liquid.
• Press the TEMP button. The display will switch to temperature (in Celsius only).
• To return to TDS mode, press the TEMP button.

Changing the Batteries
• Remove the battery compartment.
• Install new batteries (model 357A or L1154). Be sure that the batteries are properly aligned.
• Replace the battery compartment. The meter will turn on automatically.
