Fetures: A large screen with backlight 4-bit LCD test Cond meter ATC automatic temperature compensation, there is a warming sensor product accuracy is higher, available for night use, to make up for some domestic blank, is a classic brand of pocket digital Cond meter, easy to use , stability and high, easy to carry without regular adjustments. Teaching: 1. Immerse the conductivity meter in distilled water for several hours. 2. Insert the conductivity meter into the 1413 μs/cm standard solution (25°C) and gently shake it. 3. Use a small screwdriver to adjust the potentiometer until the displayed value is 1413 (this instrument is equipped with automatic temperature compensation and automatically compensates the displayed value to the value at 25°C). 4. Wash the electrode with distilled water and blot dry with water. 5. Insert the instrument into a 152-μs/cm standard solution (25°C) and gently shake it. The displayed value should be within the tolerance range as compared to
1. Gently shake the instrument for a few moments during measurement. Do not allow air bubbles on the electrodes. This will affect the measurement results. 2. Can not adjust the instrument at will, only if the instrument has been used for a long time, or if it is used frequently, it should be recalibrated 3. If there is a large error in the indication value, the indication jumps, the indication does not return to zero, etc., the following parts of the instrument immersion line should be inserted into the alcohol to shake a few times to clean the sensor. At low or humid conditions, the indication does not return to zero (the last digit of the display is less than 2) and does not affect the measured value. Battery installation: If the brightness of the backlight is significantly reduced, the display value is blurred, and the displayed value is large, replace the battery. When replacing the battery, pull out the battery compartment to replace it, pay attention to the polarity of the battery Steps 1. Remove the protective cover 2. Wash the electrode first with distilled water and dry the moisture attached to the electrode with filter paper. 3. Switch on the switch located on the battery compartment. 4. Insert the conductivity meter into the test solution until the liquid immerses to the bottom slightly at the “immersion line”. 5. Stir gently until the value stabilizes and read the displayed value. 6. After use, clean the electrode, turn off the switch and put on the protective cover.
