After a review of the preparation steps the Conductivity
Calibration screen appears.
5. Enter the Specific Conductivity of the calibration solution into
the box next to µS/cm @25° C.
6. Click Start Calibration.
Software will monitor the conductivity and temperature
readings, calculate the cell constant (sometimes called the
“Kcell”), and inform you when the response meets the criteria
for Nominal Stability.
7. You can click Accept... at any time to continue. For best
results, wait until Full Stability is reached. At that time, the
next screen is displayed automatically.
8. Look at the Proposed Cell Constant before you Commit the
value to the sensor. It should be in the range 0.98 to 1.02.
Section 5: Conductivity
TIP: “Delta” is the
change in sensor
response between
the last two readings. This
enables you to follow the
progress of the stabilization.
However, deviation from
the previous reading is not
necessarily the best indicator of
stability because the software
evaluates longer-term trends.

TIP: The Write
Defaults button restores
the factory cell constant
to the sensor.
