concentration to low-concentration, you need to rinse the electrode with distilled or deionized water, otherwise it will affect the accuracy significantly. 4.5.5 Typically the meter needs to be calibrated before use every time. But when requirement of accuracy is low, calibration is not necessary. Or try the electrode in the calibration solution, if the error is very small, calibration is not necessary. - Page 11 , the LCD will show a blinking 4.00 pH, a stable pH value and a and stay, then again press blinking C3 will be displayed, indicating the second-point calibration has been finished and the meter enters the third-point calibration. 5.2.4. Rinse the pH electrode in distilled water and dry it, then soak it into the pH 10.01 buffer solution, stir the electrode gently and let it stand still,, waiting for a stable reading and a smiley face icon to appear , the LCD will show a blinking...

Sample Test Soak the pH electrode into the sample solution after rinsing and drying, hold the electrode still. Take the readings when the smiley face icon shows up and stays on screen (indicates a stable reading). pH isothermal measurement principle According to the theory of Isothermal measurements, the smaller the difference of the temperatures between test solution and the calibration solution, the higher the measument accuracy is. - Page 13 (NIST series) — 1.68, 4.01, 6.86, 9.18 and 12.45 pH ( (China series) — 1.68, 4.00, 6.86, 9.18 and 12.46 pH (c) Press key to enter next parameter setting or press key to confirm and return to measurement mode. 5.4.3.

5.5.6. How to clean and renew your pH electrode For general contaminants, soak the electrode in Apera’s cleaning solution (AI1166) or detergent water for 30 minutes. Then use a soft brush to remove the contaminants. Afterwards, soak the probe in Apera 3M KCL soaking solution (AI1107) for at least 1 hour. -

A still display of -2.00 pH or 19.99 pH — this icon appears when the value has surpassed the measuring 5.6.1 range. There will also appear such signs when the electrode is not well connected with the meter or when the electrode is not immerged into the solution. This is a normal phenomenon. Err1 —... -

measurement mode automatically. Calibration Note: The meter’s conductivity mode has been calibrated before leaving factory, so generally users can use it directly. The conductivity can only can be calibrated under the mode of COND. Resistivity (RES), TDS, Sailinity (SAL) are coverted from conductivity so they don’t need calibration as long as conductivity is calibrated. 7.3 Sample Test: 7.3.1 Connect the 2301T-S probe to the meter, soak it into sample solution, stir gently and let it stand still. - Page 19 7.4.3. The temperature compensation coefficient of the meter setting is 2.00%/℃ by default. However, the conductivity temperature coefficient is different for different solutions. Users can refer chart (7-2), as well as the data which they receive from experiments to set in the parameters setting of P4. At the same time, meter will do automatic non-linear temperature compensation in the high purified water which less than 10 μ...
