5.5 pH Calibration Report
The meter allows checking of the calibration data of the pH electrode for diagnostic purposes.
5.5.1. Press the mR key in the pH measurement mode, the display
shows “LOC/P-01”.
5.5.2. Press
▲ or ▼ key until the display shows “ELE/P-02” (Electrode Diagnosis).
5.5.3. Press ENTER key to confirm, the meter shows the last calibration date (Format: mm-dd).
5.5.4. Press
▼ key, the meter shows “OFS” (zero-point offset potential).
5.5.5. Press
▼ key again, the meter shows the slope of each pH buffer group.
5.5.6. Press the ON/OFF key to return to measurement mode.
If the meter is not calibrated or calibration is not successful, the display will show "----" only.
