VII. How to calibrate the pH meter BR, Br, Br

1. Clean the electrode with clean water and wipe it dry with a soft paper towel. BR, Br, Br

2. Immerse the electrode in the prepared standard solution ph6.86, and wait until it is stable. BR, Br, Br

3. Press and hold the M (P) key for 3 seconds to enter the function menu, and find the menu where the main display screen displays cal and the sub display screen displays "-------". "Br", "br", "br"

4. Press the λ key once, and P1 will be displayed on the secondary display screen. "Br", "br", "br"

5. Press the M (P) key once, and the main display screen displays PL, and the sub display screen displays 6.86 (if it is not 6.86, you can press Λ and V to modify it). "Br", "br", "br"

6. Press the M (P) key once, the main display screen displays 6.86, and the sub display screen displays No. "Br", "br", "br"

7. Press the λ key once, and the secondary display screen displays yes. BR, Br, Br

8. Press the M (P) key once, and PL will be displayed on both the main display and the sub display. "Br", "br", "br"

9. After a few seconds, the main display shows cal, The secondary display screen shows "-------" P1 point correction is complete. "Br", "br", "br"

10. Repeat steps 1---9, just change the standard solution to ph4.00 (or ph9.18), and complete the correction of P2 point. "Br", "br", "br"

VIII. How to calibrate the ORP meter "br", "br", "br"

ORP electrode is different from the pH electrode, which needs to be corrected with standard solution, but the most important purpose is to check the ORP electrode with MV standard solution to see whether the electrode is invalid. "Br" BR, Br

1. Clean the electrode with clean water and wipe it dry with a soft paper towel. BR, Br, Br

2. Immerse the electrode in the prepared MV standard solution and wait for the display to be stable. BR, Br, Br

3. Check whether the displayed value is close to the value of MV standard solution. If the error is within plus or minus 35mV, the electrode can be used normally, otherwise it needs to be replaced.

through M (P) Key under the HB menu, use Λ or V key to modify the parameters of the sub display screen to the interval value to be controlled by the high limit. BR, Br, Br

for example, it is required to control the addition of bleaching water and control the 0rp value of the medium between 500 and 600. BR, Br, Br

setting method: hial is set to "600", Hb is set to "30". BR, Br, Br

use the M (P) key to modify the parameters of the sub display screen to the low limit control target value under the l0al menu with Λ or V key. BR, Br, Br

use the M (P) key to modify the parameters of the sub display screen to the interval value to be controlled by the low limit with Λ or V key under the LB menu. BR, Br, Br

for example, it is required to control the addition of sodium sulfide and control the ORP value between 70 and 100. BR, Br, Br

setting method: loal is set to "100" and LB is set to "30". BR, Br, Br

12. Common faults and treatment methods BR, Br, Br
