    3. USE IN STAND-ALONE MODE ■ The instrument can operate in two modes: ■ the stand-alone mode described in this section, ■ the record mode, in which it is controlled by a PC. This mode is described in the next section. To ensure proper operation of the instrument, always leave the cell connected and the cap on the USB connector.

The instrument displays the conductivity measurement and the temperature measured, the reference temperature and the time.
  • Page 14 3.1.3. CALIBRATION PROCEDURE Calibration serves to determine the constant of the conductivity cell. In order to avoid the influence of the temperature, do the calibration at the temperature at which you will be making measurements. ■ With the instrument set to conductivity measurement, press the CAL key.
  • Page 15 Do not withdraw the cell from the solution until the measurement is over. To abort the calibration of the cell, long-press the END key before the end of the measurement. Otherwise, when the measurement is over, the new calibration is applied. ■...
  • Page 16: Conductivity Measurement

    3.2. CONDUCTIVITY MEASUREMENT When the calibration is over, the cell is ready to make measurements. Use a cell suited to the medium to be measured. Between measurements, the cell must be rinsed, then dried. For each measurement, wait for the measurement to stabilize and for the temperature to be correctly established. Conductivity is the capacity of a solution to conduct electric current.
  • Page 17: Resistivity Measurement

    You must then correct the temperature displayed, using the ▲ and ▼ keys, so that it is equal to the measured temperature of the solution. The instrument corrects the response of the cell as a function of the temperature. To calibrate the cell, always correct the temperature first. 3.3.
  • Page 18: Tds Measurement

    3.4. TDS MEASUREMENT The TDS (Total Dissolved Solids) measurement is used to estimate the level of dissolved solids in a solution. You must first calibrate the cell for conductivity and parameterize the measurements (in particular the temperature correction, the reference temperature, and the TDS factor) before making TDS measurements. ■...
