Conductivity Calibration
The ECscan series tester allows up 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. 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.
1.1 Press the Cal key, the tester shows ----/CAL 1.
1.2 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.
1.3 Press the Enter key, the default calibration value begins flashing.
1.4 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.
1.5 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.
2.1 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.
2.2 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.
1. Press and hold the Cal key to enter the setup menu.
2. Press the Enter key until the display shows /or /.

ECscan series I4
3. Press the Cal key, the tester enters the temperature calibration
mode.
4. Place the electrode into a solution with a known accurate
temperature and wait for the measurement to stabilize.
5. Press the Cal key to modify the temperature value.
6. 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),
(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.
•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.
1. Twist the electrode collar counter clockwise, pull 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.

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.

Calculating the TDS Conversion Factor
To determine the TDS factor of sample solution use the formula below.
Factor =
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.
