TDS meters are most accurate when calibrated as close as possible to the sample to be tested. For best results, calibrate at 25°C (77°F). To ensure accuracy and consistency, recalibrate your meter using a commercial standard solution. This can be done prior to usage and should be done after prolonged usage. For drinking water, we recommend calibrating in a range of 90ppm to 700ppm. Step 1: Measure the TDS level of the solution (follow usage instruction above). Step 2: If the meter does not read within 2% of the solution, adjust the reading by inserting a mini-screwdriver into the trimmer pot (small hole on the rear of the meter). Gently turn the trimmer clockwise to increase the reading and counterclockwise to decrease the reading. - Make sure the screwdriver fits evenly into the groove of the screw. - Note that the trimmer pot is very sensitive! Remove the screwdriver carefully. - Try to keep the meter vertical. Step 3: Once the meter reads within 2% of the solution, gently release pressure on the screwdriver and remove from the trimmer pot. - If the screwdriver is retracted abruptly, the reading may jump. Step 4: With the meter in the solution and the reading at the correct level, press the ‘HOLD’ button. Let the reading hold for approximately 10 seconds to fully stabilize. Step 5: Remove the meter from the solution. Shake it to remove any water drops that may adhere to the probes and casing, creating air gaps. - Water droplets or air gaps may cause the meter to display an incorrect reading. Step 6: Turn the meter off, wait a moment and turn the meter on again. Step 7: Insert the meter into the solution and verify the reading. If the reading is accurate, calibration is complete. If not, repeat the procedure. TDS Total Dissolved Solids correlates to the ability of water to conduct electricity. It is also an index used to determine the concentration of dissolved minerals. The more minerals that are dissolved, the more conductive the water will be. A TDS meter is calibrated to read in parts per million (ppm). TDS is the concentration of a solution as the total weight of dissolved solids. (1 ppm = 1 milligram/liter. TDS is a mass estimate and is dependent upon the mix of nutrients as well as the concentration.

TDS meters are most accurate when calibrated as close as possible to the sample to be tested.
For best results, calibrate at 25°C (77°F).
To ensure accuracy and consistency, recalibrate your
meter using a commercial standard solution. This can be
done prior to usage and should be done after prolonged

Gently turn the trimmer clockwise to increase the reading
