10 USE AND CARE Operating the TDS Meter BATTERY COMPARTMENT ON /OF F ON/OFF MAXIMUM IMMERSION LEVEL ALWAYS CHANGE FILTER CARTRIDGE WHEN TDS METER READS "006" 1. Remove the cap from the end of the TDS Meter. 2. Push the "ON/OFF" button. The meter should read "000". 3. Place the end of the meter in one inch of water. Do not fully submerge the TDS Meter; this may short circuit the battery. 4. Wait a few seconds for the reading to stabilize. You can read the number when you remove the meter from the water. 5. Do not use in hot water. CHANGING THE TDS METER BATTERIES (two 1.5v button cell) 1. Use a fingernail to remove the cap at the end that says "TDS". 2. Replace the old batteries with two new batteries (Battery Type LR44). 3. Replace the cap. UNDERSTANDING THE TDS METER The TDS meter helps you put a number on what your taste buds are already telling you about what's in your water. It measures for the things in water that can give it a taste. The higher the reading on the water, the more substances dissolved in your water. For a more scientific explanation, it is showing you the total number of detectable dissolved solids in water. With the push of a button, the electrodes in the bottom of the tester measure the amount of ions in the water and convert that amount to a number that displays on the screen. The number represents the amounts of detectable dissolved solids in parts per million that exist in your water sample. The meter is primarily used to indicate ZeroWater® filter replacement at 006. It may also be used as a simple method to compare water quality by displaying the Total of the Dissolved Solids (TDS) in parts per million only. The meter does not specify what substances comprise the Total. The meter should not be used to assess the safety or purity of water, which should only be undertaken by a qualified laboratory.
