B) wait for the indicator to stop moving and take a pH reading. C) gently dry the test stick, insert it into the slot close to the tester and store. Chlorine Level Test: 1.2 to 1.7ppm is recommended for pool or spa water. A) move the indicator to the "adjustment point" position. B) Holding the tester in one hand and the test rod in the other, put the metal rod into the water to the black position. Wait for the indicator to stop swinging to read.

Usage:Storage Method:To prolong the life of the PC-104 pool tester and ensure accurate measurementsAdjustment points: before first use, adjust the pool or spa water tester in the following order: 1. Test the pool or spa water with a traditional liquid testing tool; 2. Write chlorine reading to standby (1.5ppm); 3. No need to adjust PH. To find the tester adjustment point: A. Place a 1.5V AA battery (positive side up) into the battery compartment of the handle. B. Hold the tester in one hand and the test stick in the other. C. Insert the cleaned metal rod into the water to the black position. D. Gently stir the water using a metal rod. When the metal rod is stored in water, turn the dial on the front of the watch in the CL direction until it can no longer move. Then slowly back to the right until the indicator points to the position of the result measured by a traditional liquid test tool (e.g. 1.5). F. Remove the test rod from the water, taking care not to move the knob. The pointer will move to the right, stopping at a letter between a and E. This letter is the adjustment point. Note: The meter must be set to the "adjustment point" before each chlorine test. Cleaned probe: A) using the super-fine 600 grit sandpaper provided in the kit, gently wipe the metal probe to remove any buildup. B) wash the probe with light soap and water; Towel dry it with clean paper C) wait 3 - 5 seconds to reduce static electricity.
