How to find adjustment point for testing
1. Insert 1pc AA 1.5V battery in the compartment in the handle.
2. Hold the tester in hand and the probe in the other.
3. Insert the cleaned metal probes into the water up to black band.
4. Stir the water slightly with the probe.
5. With the probe still in the water, turn the wheel on the face of the tester all the way to the left towards"CL". Slowly turn the wheel back to the right until the needle matches the level you recorded with the convention liquid tester(e.g.: 1.5ppm)
6. Remove probes from the water without touching the wheel. Indicator will move all the way to the right and stop on a letter between A and E. This letter is your "adjustment point".
Note: Any time you use this tester to test the level, you must adjust it to the "adjustment point" before testing.
Test pH Level:
Recommended pH level for pools and spas: 7.2 ~ 7.8
1. With the probes still in the water, turn the wheel all the way to "pH" until it clicks(battery must off for pH reading).
2. Wait until the needle rests on the pH reading.
3. Gently dry probes and insert into the holder on the side of the tester for storage.
