ECscan20/30/40 Overview Thank you for selecting the ECscan series pocket conductivity tester. This manual provides a step-by-step guide to help you operate the instrument, please carefully read the following instructions according to the model you have purchased. Installing the Batteries Twist the electrode collar counter clockwise, pull the electrode away from the tester.
ECscan20/30/40 Switching the Tester On and Off Press and hold the Meas key for about 5 seconds to switch on the tester. • • Press and hold the Meas key to switch off the tester. • To enable the auto-power off function, refer to the Setup Menu section.
ECscan20/30/40 Conductivity Calibration The ECscan series conductivity tester allows 1 to 3 points calibration. For better accuracy, we recommend that you perform 3 points calibration or select a standard solution closest to the sample conductivity you are measuring. The tester will automatically detect the calibration standard and prompt the user to perform the calibration.
ECscan20/30/40 Temperature Calibration The ECscan series tester has a built-in temperature sensor that used for automatic temperature compensation (ATC). Durning the measurement, if the measured temperature reading differs from that of an accurate thermometer, the tester needs to be calibrated.
ECscan20/30/40 Appendix Preparation of Conductivity Standard Solutions Place the analytical grade potassium chloride (KCl) reagent in a beaker and dry in an oven for about 3 hours at 105° C/221° F, then cool to room temperature. Add the reagent to a 1 litre volumetric flask according to the instructions in table below.
