Important information on the calibration
- Before and after immersing the electrode into a pH solution, rinse it with distilled water.
- Calibrate each pH solution twice, if possible.
- It is recommended to calibrate in two steps: pH 7 first, followed by pH 4, then calibrate pH 7
again and then pH 10.
- If the calibration solution deviates by 2 pH,
“ERR” will appear in the display.
