bluelab Pro Controller Wi-Fi - Conductivity Calibration

6.6 Conductivity Calibration
The Conductivity probe is factory calibrated. It is unlikely that you will need to calibrate
it, but it can be calibrated if required.
For accurate calibration and measurement, the probe should be cleaned before
calibration. See Conductivity probe cleaning in Section 6.4.
Ensure
the
probe
has
been
cleaned
and rinsed well with fresh water.
Shake off excess water. Water still on
the probe after rinsing can lower the
reading and cause an inaccurate
calibration.
Place
some
2.77
EC
calibration
solution into a clean dry container.
Place the conductivity probe into the
solution for a few minutes to allow the
probe to adjust to the solution
temperature.
3.
Select
calibrate
mode.
Press the conductivity measurement
button. The current reading will be
shown on the actual display, and EC
CAL on the right. A calibration offset
value will be displayed brighter than
the other numbers at the top of the
right-hand display.
4.
Calibrate
by
pressing
the
value
increase/decrease buttons to bring
the actual reading to the value of
the calibration solution. The
calibration offset value will also
increase or decrease as this is done.
When the actual value is the same
as the calibration solution (2.8 EC),
press the mode select buttons to exit
calibration mode. This saves the
calibration, and calibration is
complete.
Note: For Bluelab 2.77 EC solution, a display of
2.8 EC should be expected.
