3. Conductivity Calibration
3.1. Press key to enter in conductivity measurement mode, rinse the probe in pure water
and dry it.
3.2. Fill certain amount (about half volume of the calibration bottle) of 1413μS and 12.88mS
standard solution in separate calibration bottles;
3.3. Long press to enter calibration mode; Short press to exit.
3.4. Dip the probe in 1413μS standard solution and stir gently, leave to stabilize
(LCD displays as shown in the picture on the right). Short press to
complete 1-point calibration. The tester then returns to measurement mode
and calibration icon will appears one the LCD.
3.5. For multi-point calibration (either 2 or 3 point), rinse the probe in clean water and repeat step
3.4 using 84uS standard solution and / or 12.88mS standard solution. After completion of each
point, the calibration icons (for 84uS) and (for 12.88mS) will appear on the LCD near the
.
4. Conductivity Measurement
4.1. Short press to turn on the tester. Rinse the probe in pure water and dry it. Dip the probe
in sample solution, stir gently, leave it to Stabilize, Get reading after LCD displays .
4.2. Press to switch between parameter:

5. Special Notes
5.1. The tester uses 84μS, 1413μS and 12.88mS conductivity standard solution. User can conduct 2
or 3 point calibration. Refer to the chart as follows. Generally, calibrating the tester with 1413μS
conductivity standard solution alone will meet the testing requirement.
