• Air bubbles below the sensor when in solution can cause a slow response or error in the
calibration. Make sure to remove air bubbles during calibration.
• If the rugged probe does not easily go in the calibration container, remove the shroud. Refer to
Remove or install the shroud on page 9.
5.2 Calibration procedure
1. Go to the
calibrate menu.
Select the probe, if
applicable. The
display shows the
conductivity
standard solution to
use for calibration.
2. Pour the fresh
standard solution
into a beaker.
3. Rinse the probe
with deionized water.
Dry the probe with a
lint-free cloth.
4. Put the probe in
the standard solution
with the sensor fully
in the solution. Do
not put the probe on
the bottom or sides
of the beaker.
5. Shake the probe
from side to side to
remove air bubbles.
6. Stir gently, then
read the conductivity
value of the standard
solution. The display
shows the
temperature-
corrected
conductivity value
when the reading is
stable.
7. Save the
calibration.
Section 6 Sample measurement
The procedure that follows is applicable to meters that can connect to Intellical conductivity probes.
Refer to the applicable meter documentation for meter operation and probe-specific settings.
6.1 Sample measurement notes
Read the notes that follow before sample measurements.
• Rinse the probe with deionized water and dry with a lint-free cloth between measurements to
prevent contamination.
• If complete traceability is necessary, enter a sample ID and operator ID before measurement.
Refer to the meter manual for instructions.
