Conductivity Calibration
One to five conductivity standards can be used for calibration. Always use fresh standards and select
standards that are near the sample conductivity. Prepare the conductivity cell according to the instructions in
the conductivity cell use guide. Connect the conductivity cell and any other electrodes to be used to the meter.
Power on the meter and set the measurement mode to conductivity.
Note: For an automatic calibration, the nominal cell constant of the conductivity cell must be entered in the
setup menu before the calibration is performed and Thermo Scientific Orion 100 uS/cm, 1413 uS/cm and/or
12.9 mS/cm conductivity standards must be used.
Automatic and Direct Calibration
1. In the measurement mode, press f1 (cal).
2. Rinse the conductivity cell and any other electrodes in use with distilled water, blot dry with a lint-free
tissue and place into the standard.
3. When the conductivity cell and standard are ready, press f3 (start).
4. Wait for the conductivity value on the meter to stabilize and stop flashing and perform one of the
following actions:
a. Press f2 (accept) to accept the displayed conductivity value.
b. Press
f3 (edit) to access the numeric entry screen and edit the conductivity standard value.
i. Press
, , or to highlight a number or decimal point, press f3 (enter) to select
the highlighted item and repeat until the standard value at the measured temperature is shown.
ii. Press
f2 (done) to exit the numeric entry screen.
iii. Press
f2 (accept) to accept the entered conductivity value.
5. Press f2 (next) to proceed to the next standard and repeat steps 2 through 4 or press f3 (cal done) to
save and end the calibration. If five standards are used, the calibration will save and end once the fifth
conductivity standard value is accepted.
6. The meter will display the calibration summary including the average calculated cell constant. Press
f1 (meas) to export the data to the calibration log or press f2 (print) to export the data to the calibration
log and a printer or computer. The meter will automatically proceed to the measurement mode.

Measurement
Press while taking a measurement in the continuous measurement mode to freeze the display and
press a second time to unfreeze the display and continue the measurement. Press while taking
a measurement to manually export the measurement to the data log, if the data log is enabled in the
setup menu.
1. Ensure the measurement mode is set correctly. To set the measurement, press to scroll through the
conductivity, TDS, salinity and resistivity measurement modes.
2. Rinse the conductivity cell electrode and any other electrodes in use with distilled water, blot dry with a
lint-free tissue and place into the sample.
3. Start the measurement and wait for it to stabilize.
a. If the meter is in AUTO-READ mode (default setting), press to start the measurement. When
the icon stops flashing, record the conductivity, TDS, salinity or resistivity and temperature of
the sample. Press again to start a new measurement.
b. If the meter is in continuous mode, the meter will immediately start taking a measurement and
update the display whenever the measurement changes. Wait for the display to show ready and
record the conductivity, TDS, salinity or resistivity and temperature of the sample.
c. Star A322 meter only – If the meter is in timed mode, the meter will log measurements at the
preselected time interval, regardless of the measurement stability. The meter will update the display
whenever the measurement changes, so the conductivity, TDS, salinity or resistivity and temperature
of the sample can be recorded when the display shows ready.
4. Remove the conductivity cell from the sample, rinse with distilled water, blot dry and place into the
next sample.
5. Repeat steps 3 and 4 for all samples.
6. When all samples have been measured, store the conductivity cell according to its user guide.
