Three conductivity test pen usage operations:
Remove the protective cover.
Press the / switch to turn on the power.
Insert the conductivity test pen into the solution being measured until the liquid is immersed slightly below the immersion line.
Shake gently to remove air bubbles in the electrode
After the displayed value is stable (about a second), press the reading button, lock the number, and the words will appear on the display. You can take out the conductivity test pen to read the liquid level. Press again to unlock
If the word flashes on the display, the reading needs
After use, turn off the power, clean the electrode with clean water, and put on the protective cover.

Precautions for the four conductivity test pens
The conductivity test pen is not waterproof, do not let the solution exceed the immersion line
It cannot be adjusted at will, the conductivity test pen has been adjusted before leaving the factory Correction.
If the indication error is large, the indication value jumps and the indication value does not return to zero, the conductivity test pen below the immersion line should be inserted into alcohol and shaken for a few times to clean the sensor.
Five Conductivity Test Pen Battery Installation
If the display is blurred or does not display, and the display value error is large (after cleaning the electrode with alcohol), the battery voltage should be checked. If it is lower than the battery voltage, the battery should be replaced in time. When replacing the battery, pull out the battery compartment to replace it. Pay attention to the battery polarity.
