Page 20: Calibration Frequency
5.1.3 Calibration Frequency The frequency that you need to calibrate your meter depends on the tested samples, condition of electrodes, and the requirement of the accuracy. For High-Accuracy measurement (≤ ±0.02pH), the meter should be calibrated before test every time; For general-accuracy measurements (≥±0.1pH), once calibrated, the meter can be used for about a week or longer. - Page 21 Table-5 pH Meter 3-point Calibration 1. Long press to enter calibration mode. Rinse off the electrode with distilled or deionized water. Shake-dry or dry with filter paper. Then insert the electrode into 7.00 pH buffer. Press to continue. 2. Stir the electrode gently, let it stand in 7.00 pH buffer, and wait for to show up and stay on screen (the buzzer will make a beep).
- Page 22 5. When pH 4.00 is calibrated, the 4.00 icon will show up at the bottom left corner. The meter will automatically enter the next point of calibration. Rinse off the electrode with distilled or deionized water. Shake-dry or dry with filter paper.

Page 26: About Ph Measurement
About pH Measurement 5.6.1 pH Stability Criterion pH stability criterion refers to the time it takes for pH readings to stabilize, which is related to the ion concentration (iconic strength) of test samples. Generally, the higher the ion concentration, the faster the readings get stabilized. -
Page 27: Ph Isothermal Measurement Principal
◆ Min-Max alarm If the reading is lower than the minimum value or higher than the maximum value, reading alarm goes off. For example, if minimum value is set to 6.50 pH, and maximum value is set to 7.60 pH, when measurement is lower than 6.50 pH or higher than 7.60 pH, shows up, and the buzzer makes a beep. -
Page 28: Calibration Solutions
5.7.2 Calibration Solutions To maximize the meter’s measurement accuracy, pH buffers should be fresh and clean. After multiple uses, replace pH buffers in time. 5.7.3 Cleaning pH electrodes must be thoroughly rinsed with pure water before and after each test. For tough contaminants, users can use a soft brush and warm soap water to clean off. -
