Sartorius PB-10 pH/Acidity Meter - Operating Procedures
1. Purpose: This regulation is formulated to standardize the operation of the acidity meter, correctly use and maintain the acidity meter, and ensure the accuracy of the values.
2. Scope of application: This regulation applies to the Sartorius PB-10 acidity meter.
3. Executor: All laboratory technicians who use the balance.
4. Operation steps:
4.3.1 Startup
Wiring and Circuit Connections:
——Connect the transformer plug to the power interface of the acidity meter;
Connect the electrode plug and temperature compensation plug to the corresponding plugs of the acidity meter. Power on:
——Turn on the power switch to turn on the device and preheat it for thirty minutes. Open the electrode filling hole, unscrew the electrode protective cap, clean the electrode with distilled water, and dry it with filter paper for later use.
4.3.2 Sartorius PB-10 pH/Acidity Meter - Calibration
The meanings of each key in the interface:
Mode: Conversion key, used for converting pH, Mv, and relative Mv measurement methods;
Setup: Set key, used for * * buffer solution, to retrieve electrode calibration data or select self recognized buffer solution;
Standardize: calibration key, used to identify buffer solutions for calibration; Enter: Confirm key, used for menu selection confirmation.
4.3.2.1 Press the "Mode" button to adjust the measurement selection to the pH measurement interface, and then press the "Enter" button.

4.3.2.2 Press the "Setup" button once, and the screen will display "Clear", indicating all previous settings
Correct the data and then press the "Enter" key * * for past data.

4.3.2.3 Insert the electrode into a buffer solution with pH=6.86, stir thoroughly, press the "Standardize" button, and the acidity meter will automatically recognize the buffer solution and flash to display the buffer value. After reaching a stable state, confirm with the "Enter" button to calibrate the positioning point; The pH meter shows a slope of 100.0% for the electrode.

4.3.2.4 Clean the electrode with distilled water and dry it with filter paper. Then insert it into a pH=4.0 (or pH=9.18) buffer solution and stir thoroughly. Press the "Standardize" button, and the acidity meter will automatically recognize the buffer solution and flash to display the buffer value. After reaching a stable state, confirm with the "Enter" button to correct slope point 1. The pH meter should display the slope of the electrode, which should be between 95% and 105%. Otherwise, it indicates that the buffer solution is no longer available and calibration buffer solution should be prepared again for calibration.

4.3.2.5 Clean the electrode with distilled water and dry it with filter paper. Then insert it into a pH=9.18 (or pH=4.0) buffer solution and stir thoroughly. Press the "Standardize" button, and the acidity meter will automatically recognize the buffer solution and flash to display the buffer value. After reaching a stable state, confirm with the "Enter" button to correct slope point 2. The pH meter should display the slope of the electrode, which should be between 95% and 105%. Otherwise, it indicates that the buffer solution is no longer available and calibration buffer solution should be prepared again for calibration.
Note: The measuring solution tends to be acidic, and pH 4.0 buffer solution is generally used to correct the slope; On the contrary, when the measuring solution is alkaline or neutral, a buffer solution with pH=9.18 is generally used to correct the slope.
4.3.2.6 Instrument calibration completed. Clean the electrode with distilled water and dry it with filter paper for later use; Or put it back into the protective cap and use it after cleaning it next time.

4.3.3 Sartorius PB-10 pH/Acidity Meter - Measuring pH Value
4.3.3.1 When the temperature of the test solution and the calibration buffer solution are the same, clean the electrode with the test solution once, then add the test solution, stir the solution with a glass rod to make it uniform, and read the pH value of the solution on the display screen.
4.3.3.2 When the temperature of the test solution is different from that of the calibration buffer, clean the electrode with the test solution once, then add the test solution, stir the solution with a glass rod to make it uniform, and the pH meter will automatically compensate for the temperature. The pH value of the solution will be read on the display screen.
After the measurement is completed, clean the electrode with distilled water and dry it with filter paper, then put on the electrode protective cover.

4.3.3.4 When used frequently, soak the electrode in a saturated potassium chloride solution to keep the electrode glass ball moist
