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

1 2 ... 27 28 29 30 31 32 33 34 35 36 37 ... 55 56
