Page 7: Connectors
Connectors The meter adopts 8-pin connector, into which pH, ORP, and conductivity electrode can be connected. When connected, the meter will automatically switch to the correspondent measurement mode. Display Mode 3.4.1 Stable Reading Display Mode When the measuring value is stable, the screen displays as shown in Figure-2. - Page 8 Table-2 pH Standard Calibration Solution Series Calibration Icons USA Series NIST Series 4.00 pH 4.01 pH 3-point 7.00 pH 6.86 pH calibration 10.01pH 9.18 pH 4.2.2 pH Calibration Modes The instrument has 1 to 3 points auto calibration mode. The 1 point must be 7.00 pH (or 6.86 if using NIST).

Page 10: Sample Measurement
Sample Measurement 4.4.1 Rinse the pH electrode in distilled water, dry it, and dip it into sample solution. Stir the solution gently and let it stand still in the sample solution until icon appears and stays on LCD, get the pH reading, which is pH value of sample solution, please refer to Figure-5 for calibration and measurement process of the pH meter. -

4.4.3 pH isothermal measurement principle According to the pH isothermal measurement principle, the closer the test sample’s temperature is to the calibration solution’s, the higher the accuracy of the measurement. So this principle is recommended to follow when conducting tests. 4.4.4 Restore to factory default The instrument has a function to return to factory default setting, which can be set up in P1.2 (refer to section 7.3). -

Table-6 °C 5.2.2 Clean and activate ORP electrode After the electrode has been used over a long period of time, the platinum surface will get polluted which causes inaccurate measurement and slow response. Please refer to the following methods to clean and activate ORP electrode: (a) For inorganic pollutant, soak the electrode in 0.1mol/L dilute hydrochloric acid for 30 minutes, then wash it in distilled water, then soak it in the 3M KCL storage solution for 6 hours. -

connected, the meter will automatically switch to conductivity mode (no need to switch manually). Please do not pull the cable in case of poor contact. Make sure the connector is clean and dry. See more information regarding the conductivity electrode’s maintenance in section 6.6. Information regarding Conductivity Calibration 6.2.1 Conductivity Standard Calibration Solutions The meter uses conductivity standard solution of 84 μS/cm, 1413 μS/cm, 12.88 mS/cm and 111.8 mS/cm. -

TDS & Conductivity 6.4.1. TDS and conductivity is linear related. The conversion factor is 0.40-1.00. Adjust the factor from parameter P2.6. The factory default setting is 0.71 and please refer to section 7.4. The meter only needs to be calibrated in Conductivity mode, then after calibration of conductivity, the meter can switch from conductivity to TDS. -

6.5.4. Factory default setting For factory default setting, please refer to parameter setting P2.7 (Section 7.4). With this function, all calibration data is deleted and the meter restores to the theory value. Some functions restore to the original value (refer to appendix -1). When calibration or measurement fails, please restore the meter to factory default setting and then perform re-calibration or measurement. -
