How to calibrate the device correctly:
- One bag powder dissolved in 250ml pure water,when you need to do the calibrate,take some solution,the rest of the solution can Sealed preservation 1 month.
- 1. Turn on the machine, put the PH818 in pure water, clean it and wipe it with a cloth. Press and hold the calibration button, put the machine into the debugged PH4.00 solution, stir it for a few seconds, and let it stand for a few seconds until the machine screen appears. “PR5”
- 2. When the machine number becomes 6.86, take out the machine, clean it in pure water, wipe it with a cloth, put it into the debugged PH6.86 solution, stir it for a few seconds, and let it stand for a few seconds until the machine screen appears “PR5”
- 3. When the machine number becomes 9.18, take out the machine, clean it in pure water, wipe it with a cloth, put it into the debugged PH9.18 solution, stir it for a few seconds, and let it stand for a few seconds until the machine screen appears “PR5”
- 4. The machine is restored to the state when it was turned on, and the calibration is completed.
