When in Continuous Mode, to manually reach a calibration value, you need to
press the Auto-Stop button when reading is stable and displays

When in Auto End Point Mode, the meter determines when the reading is stable
then displays and locks the reading or calibration value automatically, the reading

4.1.2.2 Calibration
Place the conductivity sensor in the selected calibration standard, wait for 10-15
seconds, then:
1 Press the Cal button.
blinking during calibration.
Note:
a) Calibration starts with the Auto End Point Mode.
b) Pressing the Auto-Stop button during the calibration can end the process.
2 The meter reaches endpoint automatically according to the preselected auto-
endpoint mode. The screen will display the calibration K value. The calibrated
standard solution value will be marked in
The calibration is finished, the calibration result will be stored automatically.
Note:
To ensure the most accurate conductivity readings, you should verify your cell constant
with a standard solution before measurement and recalibrate 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 outside the range due to an improper calibration, you may need to recover
factory settings, then repeat calibration.
