:

1. Remove the protective cover.
2. Tap the "ON/OFF" switch to turn on the power.
3. Insert the conductivity meter into the measured solution until the liquid is immersed slightly below the "immersion line".
4. Gently shake the instrument and wait for the reading to stabilize before reading.
5. After use, press "ON/OFF", turn off the power, clean the electrode with distilled water or alcohol, and put on a protective cover.

:
If the display is blurry or not displayed, and there is a large error in the displayed value, the battery should be replaced in a timely manner. When replacing the battery, simply pull out the battery to replace it. Pay attention to the polarity of the battery and the direction of the battery compartment, and do not deform the battery contact piece.

【 Common Sense of Application 】:
1. After being stored for a long time, the conductivity value of purified water and mineral water increases too much compared to the beginning, and the total number of co viruses and bacteria will also increase accordingly. At this time, it is not advisable to drink raw water, as it affects health;
2. The conductivity value of pure alcohol is 0, and a value greater than 0 indicates impurity;
3. The conductivity of an aqueous solution is directly proportional to the amount of solid dissolved, so the smaller the displayed value, the lower the impurities in the water;
4. Users on the 3rd floor and above are supplied with water from the top water storage tank, which can easily cause secondary pollution. Therefore, it is recommended to regularly monitor changes in conductivity values and urge the property management department to clean regularly.
5. How much laundry detergent should be placed in the washing machine, and using a conductivity meter to measure can digitize the experience. After the cleaning process, if the reading detected before drainage is the same as that of tap water, it can be considered clean. If the reading exceeds tap water, the amount of laundry detergent should be reduced;
6. If fruits and vegetables are soaked in water and their conductivity values are found to be high, it may be suspected of chemical contamination and should be taken seriously.
7. During the process of swimming in the pool, changes in the cleanliness of the pool water can be measured, and excessive readings should be taken seriously;
8. If the reading of deep well water is above 300, it indicates that the impurity content is too high;
9. Each region and city has different conductivity values due to differences in pipelines and water sources;
10. Northern hard water contains calcium and magnesium ions, with a high conductivity value, which can lead to scaling; Generally, hard water is 150-400 (scaling). Ultra hard water (if saltwater) greater than 400 (severe scaling) (limited to testing of pre treated water).
11. After the first preparation of flower fertilizer according to regulations, measure its value, and use this number to facilitate future preparation;
12. The water used in the goldfish tank can be measured to determine its cleanliness level. If there is a significant blockage in the numerical value, water should be changed in a timely manner;
13. The water used for aquaculture can be measured for future preparation and testing.
