Note:1. You need to prepare 1.5 PPM of chlorine solution in the pool water for
calibration2. If you are unsure if the chlorine content is 1.5 PPM (or if you cannot find
a calibration point), use a traditional test strip3. After the pool has been calibrated, there is no need to recalibrate unless
it is changed to use a different pool water to measure another pool.
4. Please note that the new type and old type of this product will be sent
randomly, and make sure you will not mind before ordering.
5. Calibration method: 1. Test the residual chlorine value. Rotate to the left, and after hearing a "click" sound, the pointer will move to the right. Slowly rotate the switch to the left, adjust the pointer to the C position, then insert the probe into the water. The measurement obtained is the residual chlorine value. 2. Test the ph value. Turn the switch in Figure 2 to the far right. After hearing a "click" sound, the test can be conducted.
6. Before using the product or when taking test readings, if the results are inaccurate, please first gently sand the outer surfaces of the probe with the included sandpaper before conducting the test.

How to Use:

1. Before measuring cl2, you need to toggle the switch so that the pointer points to position c. Before measuring ph, you need to toggle the switch so that the pointer points to the center position.
