How to use:

1. Remove the protective cover.

2. Rinse the electrode with distilled water and dry it with filter paper.

3. Turn on the instrument; the electrode should be immersed in the test solution.

4. Stir gently while waiting for a stable reading.

5. Close the meter, rinse the electrode, and dry it with filter paper.

Calibration Method:

1. Press the on/off button to turn on the power.

2. Press the calibration button once; the value should stabilize at 6.86 (calibrated 6.86). Remove the pH pen. Rinse the electrode with distilled water and blot the liquid.

3. Place the pH pen in the 4.00 calibration solution and press the calibration button twice until the value stabilizes at 4.00 (the 4.00 calibration is complete) (the 2-point calibration is complete).

4. Once the calibration is complete, place it in the solution of known value to be detected. If the displayed value is within the error range, this means the calibration is accurate and can be used Normally

CAUTIONS:

Clean the electrode with distilled water before and after each use.

Be careful with the glass probe as it can be somewhat fragile during use.

Remember to gently wipe it with a soft, clean cloth when finished before covering it.

Opening the battery case or replacing the battery will require recalibrating the meter.
