6. Please refer to the item 4 1 Electrode Calibration that is the standard solution calibration method Provided the standard solution is correct the accuracy can be assured so the standard solution calibration method takes the priority If the user is used to employ constant calibration method based on the constant indicated on conductivity electrode please set the electrode constant in the parameter setting of P3 refer to the item 4 5 4 The two calibration methods can be selected as the user wants and the two methods do not affect each other 4 3 3 The temperature compensation coefficient of the meter is 2 0 C for factory default However the conductivity temperature coefficient of solution of different types and different concentration varies please refer to chart 4 2 and the data from the experiment set it in the parameter setting of P2 Attention when set the temperature compensation coefficient to be 0 00 there is no temperature compensation when measuring the measured value is the conductivity value under current temperature Chart 4 2 Solution Temperature Compensation Coefficient NaCl saline solution 2 12 C 5 NaQOH solution 1 72 C Dilute ammonia solution 1 88 C 10 hydrochroric acid solution 1 32 C 5 sulfuric acid solution 0 96 C 4 3 4 Dip the conductivity electrode in the solution stir it a while and place it still to remove the bubbles and speed up the response of the electrode 4 3 5 Dur
