	Enable
	Disable (default)

Setting the Default Option

In the measurement mode, press and hold the Cal key to enter the setup menu.
If necessary, press the Cal key again to select an option.
Press the Enter key, the tester saves the current option and moves to the next menu item.
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 automatically override existing data.

The following table shows acceptable conductivity range of standard solution for each measurement range.

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

Make sure that using 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
Rinse the electrode with distilled water and place 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.

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

Temperature Calibration

The ECscan 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
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 returnto the measurement mode.

Measurement

Switching the Measurement Mode
Press the Enter key, the tester will show (conductivity), (TDS), (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, make sure that no air bubbles on the sensor surface. Wait for the measurement to stabilize and record the reading. Platinum sensor

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 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 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.

Twist the electrode collar counter clockwise, pull the electrode away from the tester.
Align the slot on the new electrode, gently push the electrode into the tester
Twist the electrode collar clockwise until tight.

Preparation of Conductivity Standard Solutions
Place the analytical grade potassium chloride (KCl) 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 liter volumetric flask according to the instructions in table below. Fill the distilled water to the mark, mix the solution until the reagent is completely dissolved.

Conductivity Standard	Reagent	Weight
84 µS/cm	KCl	42.35 mg
1413 µS/cm	KCl	745.5 mg
12.88 mS/cm	KCl	7.45 g

Calculating the TDS Conversion Factor
To determine the TDS factor of sample solution use the formula below. Factor =Actual TDS/Actual Conductivity @ 25°C

For example:
Dissolve 64 grams of the potassium chloride (KCl) reagent in 1 liter distilled water. If measured conductivity is 100 mS/cm, then TDS factor is 0.64.

Conductivity to TDS Conversion Factors

Conductivity at 25°C	ppm	Factor	ppm	Factor
84 µS/cm	40.38	0.5048	38.04	0.4755
1413 µS/cm	744.7	0.527	702.1	0.4969
