1. prepare distilled water for a clean probe between both water testing
2. First, Ph meter put in distilled water and dry it (don't wipe with a fabric)
3. After that can start to test for ph buffer powder water (ex: ph6.86)
4. before do the second ph buffer powder water (ex:ph4.0) test, please clean in distilled water and dry it, then only do the second test.

*Please do test 4-6 time for more accurate
