4.1.4 Wait for the reading to stabilize (when stays on the screen), then short press

again to nish the rst point calibration (pressing too early could lead

to Er2 error). "7.00" will be ickering and the meter will return to measurement

mode. Icon (the middle point) will appear at the bottom left, indicating a

successful 1-point calibration.

4.1.5 To calibrate the 2nd point, rinse o the electrode with pure water and remove

excess water. Dip the electrode into pH 10.01 solution and repeat Step 4.1.3 to

4.1.4. "10.01" will be ickering and (the high point) will show up next to

4.1.6 To calibrate the 3rd point, rinse o the electrode with pure water and remove

excess water. Dip the electrode into pH 4.00 solution and make a quick stir, then

repeat Step 4.1.3 to 4.1.4. "4.00" will be flickering and (the low point) will

4.2 NotesaboutCalibration

4.2.1 Always start calibrating with pH 7.00 first. Perform the 2nd and 3rd point

calibration immediately after the 1st point is finished. Do NOT turn off the

meter before you calibrate the second or third point. Otherwise, after you

restart the meter and perform calibration in pH 4.00 or pH 10.01, Er1 error

will be generated and you will have to calibrate with pH 7.00 again. For more

troubleshooting tips with calibration, refer to Section 14.

4.3HowOftentoCalibratetheElectrode?

The frequency that you need to calibrate your pH electrode depends on many factors such

as the nature of test samples, condition of electrodes, and the requirement of the accuracy.

For high-accuracy measurements (≤ ±0.02pH), the electrode should be calibrated before

every test; For general-accuracy measurements (≥ ±0.1 pH), calibrate the electrode every 1-2

weeks.

Inthefollowingcases,theelectrodemustbere-calibrated:

• The electrode hasn’t been used for a long time or a dierent electrode is connected.

• After measuring strong acid (pH<2) or strong base (pH>12) solutions.

• After measuring uoride-containing solution and strong organic solution.

• There is a significant temperature difference between the test sample and the buffer

solution.

water in a container or with a wash bottle.

To remove excessive water, just shake them o or blot dry with Kimwipe or lint-free

cloth. Neverrub the glass membrane of the electrode. Otherwise static electricity

will be generated and cause measurement error.

For tough contaminants staying on the glass membrane or junction, refer to the

following table for cleaning procedures:

Solution (SKU: AI1166) 30 – 60 minutes

Use a soft brush to help thoroughly clean o the contaminants. After the cleaning

procedure, the pH electrode should always be soaked in 3M KCl solution for 12-24 hours

for rehydration. A re-calibration is also necessary before a new pH measurement.
