ECSCAN40 POCKET CONDUCTIVITY/TDS/SALINITY TESTER Enter 4. Press CAL key to select the temperature unit ( C or F). Press ENTER key to confirm, the tester goes to temperature calibration mode, the display shows “ C/CAL”. Enter 5. If you do not want to perform temperature calibration, press ENTER key, the tester goes to next option. If needed, press CAL key to enter the temperature calibration mode, the display shows current temperature reading.
Conductivity Calibration ECscan40 tester allows up to 3 points calibration in the conductivity mode. To ensure higher accuracy, we recommend that you perform 3 points calibration or select a standard value close to the sample value you are measuring. The tester will automatically detect these conductivity standard solutions and prompt the user to calibrate the meter.

ECSCAN40 POCKET CONDUCTIVITY/TDS/SALINITY TESTER Dip the electrode into the calibration solution, the tester immediately shows current calibration standard (e.g. 1413µS/cm). Press ENTER key, the default calibration value begins flashing. Enter Press CAL key to set each digit, press ENTER key to confirm. When the setting is done, ensure the displayed value matches your calibration standard.
ECSCAN40 POCKET CONDUCTIVITY/TDS/SALINITY TESTER Press ENTER key, the default calibration value begins flashing. Press CAL key to set each digit, press ENTER key to confirm. When the setting is done, ensure the displayed value matches your calibration standard. Press ENTER key to start the calibration. Wait for the reading to stabilize, the display shows “END”. The tester returns to measurement mode.
Hold Function ECscan40 tester has two data hold modes. When the Auto-Hold function is enabled, the tester will automatically sense a stable endpoint measured value and freeze it, “HOLD” indicator will appear on the display. If the Auto-Hold function is disabled, press HOLD key, the tester will immediately freeze currently displayed value.
ECSCAN40 POCKET CONDUCTIVITY/TDS/SALINITY TESTER Electrode Care and Maintenance After each use, the electrode module should be rinsed thoroughly in deionised water. ■ If there is a build-up of solids inside the measurement area of the cell, these should be removed very carefully with a cotton bud soaked ■...
