can download how to use on the brochure page (The brochure shown It is a model with Temperature Compensation system which is different from the model that the company sells. which does not have a Temperature Compensation system, the user must set the Temp on the screen itself, but in other areas work the same including how to calibrate)

calibration method

1. Prepare pH solution (4.01, 6.86, 9.18).

2. Press the "set EO" button once.

3. Dip into the prepared solution.

4. Wait until the numbers stand still.

5. Press the OK button once.

6. Wait until the number stops and press OK 1 time.

7. The device will restart and display the current measured pH.

Repeat with other pH solutions to complete all 3 points. (4.01, 6.86, 9.18)
