3.10 Conductivity Calibration
Conductivity calibration is not generally
required. If you do notice that your
readings are not accurate, the
fi
rst thing
you should do is clean your probes.
If readings are still inaccurate the
conductivity probe can be calibrated using
a known nutrient solution of 2.77EC ( see
chart for corresponding units )
1. Place conductivity probe in
known solution.
2. Calibrate Conductivity
Select Conductivity measurement.
3. Conductivity adjustment
Adjust until actual value is 2.8EC (or
chosen unit) by using
increase / decrease keys.
