Temperature Calibration
The
ECscan series tester has a built-in temperature sensor that used for automatic temperature compensation (ATC). Durning the measurement,
if the measured temperature reading differs from that of an accurate thermometer, the tester needs to be calibrated.

Measurements
Switching the Measurement Mode
Press the
Enter
, the tester will show
(Conductivity),
(TDS),
(Salinity) icon and switch to the corresponding measurement
mode.
Measuring the Sample
Rinse the electrode with deionized 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.
•
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 a measurement endpoint and show
icon.
Press the
Meas
key to resume measuring.
Electrode Maintenance
•
Rinse the electrode thoroughly with deionized water after use.
•
Do not touch the platinum black coating on sensor surface and always keep it clean.
•
If there is a build-up of solids inside the sensor, remove very carefully, then recalibrate the tester.
•
If you do not use the tester for long periods, store the electrode with tap water.
