Real Instruments High-Precision Total Dissolved Solids (TDS) Meter with Wide Measurement Range, Automatic Temperature Compensation, Compact Waterproof Design & Accurate Water Quality Monitoring for Industrial, Environmental & Aquatic Applications (TDS-3)

• Taking TDS MeasurementsRemove 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.
• Taking Temperature MeasurementsOnce 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.PrecautionsThe meter is not water-tight. Do not dip the meter beyond the water level limit.
• Do not store the meter in high temperatures or direct sunlight.
• Do not attempt to open the housing or tinker with the electronics of the unit.
• After multiple usage, if the product is not showing correct readings, please use the recalibaration guidelines as given below.
• Re-calibration GuidelinesImmerse the TDS Meter into Calibration solution up to maximum immersion level (2 inch)Reading appear on the Display.
• If the meter does not read within 2% of solution. Press Temp key for 3 seconds, Display Start Blinking. Adjust the reading by using “Temp” key (to increase the reading) and hold key (to decrease the reading)Press Temp key again for 3 seconds, meter enters in Testing Mode. Take the TDS Meter out from water Wait a moment, after showing Zero put the meter again into water. TDS Meter show Readings.
• If Reading is accurate calibration is completed. If not, repeat the procedure
