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 .
