a . Automatic calibration (for conductivity standards of 10 μS/cm, 1413 μS/cm
and 12 .9 mS/cm) – When the µS/cm or mS/cm icon stops flashing, the
meter will display the temperature-corrected conductivity of the standard .
b . Direct calibration – When the µS/cm or mS/cm icon stops flashing,
enter the conductivity value of the standard at the conductivity reference
temperature . (Refer to page EN-12 .) Press
changed is flashing, press
and continue to change the digits until the correct value is displayed . Once
the value is set, press
5 . Press to proceed to the next calibration point, rinse the conductivity probe
with distilled or deionized water, place it into the next conductivity standard
and repeat step 4a / 4b or press
6 . The cell constant will be displayed in the main field and the meter will
automatically advance to the measurement mode .
