Note:
To ensure the most accurate conductivity readings, you should verify your cell constant
with a standard solution before measurement and recalibration if necessary. Always use
fresh standards.
For STCON3, the normal cell constant range is 1.50 – 2.00. (e.g. 1.71 /cm) if the cell
constant is out of the range due to an improper calibration, you may need to recover to
factory settings (check i-Steward menu chapter for details), and then repeat calibration.

Conductivity measurement

To switch between Auto and Continuous Modes before measurement, please refer to
Auto or Continuous End Point Mode section for details.
To start measurement:
1 Place the electrode in the sample, stir for 5 seconds and then wait for 30 seconds.
2 Press the
blink during the measurement.
3 When the meter reaches endpoint (the
icon stops blinking.), it will display the conductivity value and the temperature.
Note: in Continuous End Point Mode, you need to press the
manually end the measurement.

TDS, SAL (Salinity) and RES (resistivity) measurement

1 Touch the mode area on the screen one or several times to switch between TDS,
SAL and RES mode.
2 Follow the same procedure as for conductivity measurement.
