Dip the electrode in conductivity meter calibration solution having a temperature of 25 ° C, stirring gently for about 30 seconds.
Wait until the reading on the screen / display device are stabilized.
After this calibration device. Values shows the device must coincide with the known value of the calibration solution.
If the values on the display device different from the calibration solution 1413 μS / cm, perform calibration in accordance with instructions for use.
