Calibration for Conductivity, TDS, or Salinity
For best results, periodic calibration with an accurate standard is recommended prior to measurement. Use the
calibration standard value that is close to your intended sample value.The tester will retain one calibration value in
each mode (conductivity, TDS, salinity) when the instrument is powered off. The conductivity value can be calibrated
automatically or manually, while the TDS & salinity values require manual calibration. The tester will begin in the
measurement mode that was used when it was powered off. See "Elite CTS Measurement Parameter Setting" to
change the desired parameter.
Automatic Calibration for Conductivity
1. Remove the cap and press the
2. Dip the sensor in at least 30 mm of calibration standard.
3. Stir gently and press
4. The display will show CAL followed by the default value. CAL is indicated on the display during calibration mode.
5. If the reading is within the calibration range of the automatically recognized standards; 80 (84 µS/cm),
1410 (1413 µS/cm), or 12.90 (12.88 mS/cm), the
value has been detected.
6. Press to accept the auto conductivity standard and finish the calibration.
7. Display returns to Measurement window.
