How to Use:
1. Rinse the electrode with deionized water or rinse solution.
Press On/Off to turn on the machine. Immerse the electrode in the zero-oxygen solution for at least 3 minutes and keep shaking gently until the displayed value is stable.
2. Press the on/off key until the second line of the CAL character is displayed, and gently shake the electrode. When the displayed value is stable, press the %/L/mg key, the display DO value is 0%, and the completion is zero. Calibration.
3. Clean the electrode, immerse the electrode in a saturated dissolved oxygen solution, and continue to gently shake the electrode until the displayed value is stable.
4. Gently shake and press the ON / OFF key until the second line of the display shows the CAL character, and then press the ℃/°F key, and the DO value of 100.0% will be displayed at this time, and the slope correction is completed.
