| 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 |
|
Step1 |
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” |
|
Step 2 |
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” |
|
Step 3 |
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” |
|
Step 4 |
4. The machine is restored to the state when it was turned on, and the calibration is completed. |
