2.  If necessary, press the Cal key again to select an option.
3.  Press the Enter key, the tester saves the current option and moves to the next menu item.
4.  Repeat steps above until the tester returns to the measurement mode.

•  During the setting process, if you do not need to calibrate the temperature, press the Enter key to skip the / or / option.
• To exit the setup menu, press the Meas key.

Conductivity Calibration

The scan series tester allows up to 3 points of 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. When the calibration is completed, all new calibration values will override existing data. The following table shows acceptable standard solutions for each tester

SALscan10

Measurement Range         Standard Solution        Range Default
0 to 200 μ S/cm              70 to 170 μ S/cm          84 μ S/cm
200 to 2000 μ S/cm         700 to 1700 μ S/cm      1413 μ S/cm
2 to 20 mS/cm                  7 to 17 mS/cm             12.88 mS/cm

SALscan20

Measurement Range     Standard Solution              Range Default
200 to 2000 μ S/cm         700 to 1700 μ S/cm       1413 μ S/cm
2 to 20 mS/cm             7 to 17 mS/cm               12.88 mS/cm
20 to 200 mS/cm           70 to 170 mS/cm            111.8 mS/cm

Make sure that use the fresh standard solution during the calibration. DO NOT reuse the standard solution after calibration, contaminants in solution will affect the calibration and eventually the accuracy of the measurement.

Single Point Calibration

Ensure that you have selected 1 point calibration in the setup menu.

• Press the Cal key, the tester shows —-/CAL 1.
• Rinse the electrode with distilled water and place it into the standard solution. Stir tester gently to remove air bubbles trapped. in the slot of the sensor. The tester will automatically recognize. the standard solution and show the calibration value.
•  Press the Enter key, the default calibration value begins flashing.
• If necessary, press the Cal key to modify the calibration value, press the Enter key to confirm, and move to the next digit. When the setting is completed, make sure that the displayed value matches the calibration standard.
•  Press the Enter key, the tester begins the calibration. When the reading has stabilized, the display will show. Calibration is completed.

Multipoint Calibration

Ensure that you have selected 2 or 3 points calibration in the setup menu

• Repeat steps 1.1 through 1.5 above. When the first calibration point is completed, the display will show —-/CAL 2, the tester prompts you to continue with second point calibration.
• Repeat steps 1.2 through 1.5 above until the display shows  Calibration is completed.

1. Performing the conductivity calibration will simultaneously calibrate the corresponding salinity value.
2. To exit the calibration without saving calibrated values, press the Meas key.

Temperature Calibration

The scan series tester is installed with a built-in temperature sensor for automatic temperature compensation. During the measurement, if the measured temperature reading differs from that of an accurate thermometer, the tester needs to be calibrated.

• Press and hold the Cal key to enter the setup menu.
•  Press the Enter key until the display shows or /.
•  Press the Cal key, the tester enters the temperature calibration mode.
• Place the electrode into a solution with a known accurate temperature and wait for the measurement to stabilize.
•  Press the Cal key to modify the temperature value.
• Press the Enter key to save and press the Meas key to return to the measurement mode.

Measurement

Switching the Measurement Mode
Press the Enter key, the tester will show (conductivity), (salinity) and switch to the corresponding measurement mode automatically.

Measuring the Sample

Rinse the electrode with distilled water, place the electrode into the sample solution and stir gently, making sure that no air bubbles on the sensor surface. Wait for the measurement to stabilize and record the reading.

• During the measurement, DO NOT completely immerse the tester in water.
• If the display shows —- indicating the measurement exceeds the range, remove the tester from the sample immediately.
• If the option is enabled in the setup menu, the tester will automatically lock the measurement endpoint and show the HOLD icon. Press the Meas key to resume measuring.

Electrode Maintenance and Replacement

• Rinse the electrode thoroughly with distilled water after use.
• Do not touch the platinum black coating on the sensor surface and always keep it clean.
• If there is a build-up of solids inside the sensor, remove them carefully, then recalibrate the tester.
• If you do not use the tester for long periods, store the electrode with tap water.

Replacing the Electrode

If the tester fails to calibrate or gives fluctuating readings, you should consider replacing the electrode.

1. If the tester fails to calibrate or gives fluctuating readings, you should consider replacing the electrode.  away from the tester.
2.  Align the slot on the new electrode, gently push the electrode into the tester.
3. Twist the electrode collar clockwise until tight.
