Use test tools traditional liquid for testing water swimming pool or hot spring water; 2. Record chlorine readings are available for use (1.5PPM) 3. No need to adjust pH. Find the tester set point: A. Put a 1.5V AA battery (positive side up) in battery slot on the handle. B. Hold the tester with one hand and the test rod with the other. C. Insert the cleaned metal rod into the water to the black position. D. Gently stir the water with a metal rod. E. When the metal rod is kept in the water, turn the knob on the front of the watch in the CL direction until it can no longer be moved. Then slowly adjust it to the right until the pointer points to the position of the result measured by the traditional liquid test tool (such as 1.5). F.

Note: Before each chlorine test, the meter should be set to the set point. Test the pH value: The recommended chlorine content of swimming pool water or hot spring water is 7.2-7.8 A) Let the test stick stay in the water and turn the knob in the pH direction to beep (the battery must be removed when reading the PH). B) Wait for the pointer to stop swinging and take a pH reading. C) Gently dry the test stick, insert it into the slot next to the tester and store it. Test the chlorine content: The recommended chlorine content of swimming pool water or hot spring water is 1.2 to 1.7 ppm A) Set the pointer to the set point position ".

C) Leave the test stick in the water and continue to perform the pH test according to the instructions. specification 1. Essential tools for swimming pools, saunas and hot springs 2. The ideal tool for simply measuring the PH and C12 values of water 3. No chemical composition, no need to guess for the measurement 4. Chlorine content level within safe measuring range: 1.2-1.7 ppm 5. PH level in safe measuring range: 7.2-7.8 6. Battery: use 1 AA battery Storage method: In order to extend the life of the PC-101 Pool Tester and ensure accurate measurement, Please Note: 1. When not in use, please turn the knob to the closed position (in the PH direction until it can no longer be moved). 2. Store in a cool, dry place and avoid direct sunlight. 3.
