【BEFORE USE】: Put the included potassium chloride powder into 20ml of pure water and mix well. Then put the probe into the solution for 24 hours, take it out and clean the residual solution on the surface of the sensitive bulb. Now, you can start to calibrate. (Note: If the sponge is wet enough, please skip this step.)

【DURING USE】: If there is inaccurate calibration, repeat the step of 'Before Use'. If using your own potassium chloride powder, prepare the solution by adding 61.5g of KCL into 250ml of water. Then, put the probe into the solution for 24 hours, take it out and clean the residual solution on the surface of the sensitive bulb. Now, you can start to calibrate.

【AFTER USE】: To ensure the activity of the sensitive bulb, add a drop of newly prepared potassium chloride solution into the sponge inside the probe cover. Also, to better maintain the activity of the sensitive bulb, add the solution to the sponge every two months.
