Conductivity Technique
6. To perform an AutoCal or Direct Calibration – Wait for the µS/cm or mS/cm icon
to stop flashing.
• AutoCal – When the
µS/cm or mS/cm icon stop flashing the meter will
display the temperature corrected value of the conductivity standard.
• Direct Calibration – When the
µS/cm or mS/cm icon stop flashing the
meter will display the actual conductivity value read by the conductivity
probe. Use and / to change the conductivity value to the actual
value of the conductivity standard at the measured temperature.
7. Press
to proceed to the next calibration point and repeat steps 4 through 6
or press to save and end the calibration.
8. After the value for the last standard has been entered the cell constant will
be displayed appears in the lower field and the actual constant
appears in the main field. The meter will automatically advance to the
measurement mode. The is displayed above the main field.
To Take a Conductivity Measurement
1. Rinse electrode and place into sample. Record conductivity directly from the
main meter display when the mS/cm or μS/cm icon stops flashing indicating a
stable value. Temperature is displayed in the top left corner of the display.
2. Place the electrode in your sample.
a. If you are in continuous measurement mode, the instrument will start
measuring immediately. If you are using the benchtop meter & the stirrer
control is enabled then pressing will start the stirrer.
