CALIBRATION
Selecting the Calibration
Standard Solution
For best results, select a conductivity
standard near the sample value that
you are measuring. Alternatively, use
a calibration solution value that is
approximately 2/3 of the full scale of
the measurement range that you plan
to utilize.
For example, in the 0 to 1999 uS range,
use 1413 uS solution for calibration.
Do NOT reuse the calibration solution.
Contaminants in the solution will affect the
calibration and the accuracy. Use fresh
solution each time.
Refer to the following table. For best
results, use the recommended solution
for various conductivity ranges
