4.5. Considerations: 4.5.1. Calibration times of meter rely on the sample, electrode performance and required accuracy. For high accurate measurement ( ≤ ±0.02pH), which should be calibrated immediately with high accurate standard buffer solution, for general accuracy measuring ( ≤ ±0.1pH), which can be used almost one week or long time once be calibrated. - Page 16 4.5.7. The sensitive glass bulb in the front of combination electrode should not touch with hard things, any broken and rough will make the electrode invalidity. Before and after measuring, the electrode should be washed with purified water, and dry electrode after washing, don’t clean glass bulb with tissue for it will effect stability of electrode potential and enlarge response time.

Note: (a) The meter has been calibrated before leaving factory, so generally users can use it directly. (b) The standard solution method is aimed at the long time use of conductance electrode, which leads to inaccuracy of conductance constant. The new conductance electrode has been calibrated before being released. Its constant is marked on the electrode and input constant before use. - Page 20 6.4.2. This meter has an unique one-point calibration function, to choose one calibration solution based on the principle of the water samples and calibration solution conductivity as close as possible, in general the most common calibration solution is 1413 μS/cm. Use the equipped DJS-1 conductivity electrode (K=1), and do calibrate with 1413 μS/cm calibration solution, can use within the range of less than 100 mS/cm.
