4.3.1

Procedure for conductivity calibration (CyberScan CON 10/100/200)

1.

If necessary, press the MODE key to select

COND mode. The

µ

s indicator appears in the

upper right hand corner of the display.

2. Rinse the probe thoroughly with de-ionized

water or a rinse solution.

3.

Dip the probe into the buffer solution. The

end of the probe must be completely

immersed into the buffer solution. Stir the

probe gently to create a homogeneous

sample. Agitate the probe in the solution to

dislodge air bubbles that are trapped in the

probe.

4.

Press the CAL/MEAS key to enter the COND

calibration mode. The CAL indicator will be

shown. The primary display will show the

measured reading.

5. Use

the

!

or

"

key for CON 10, or MI/

!

or

MR/

"

key for CON 100/200, to adjust the

measured value to that of the standard

solution.

6. Wait for the measured conductivity value to

stabilize. See Figure 13 for the conductivity

calibration procedure.

NOTE: To exit without confirming the

calibration, press the CAL/MEAS key.

For calibration in the other ranges (maximum:

5 ranges, repeat steps of the procedure, this

time using a solution with a conductivity of a

different range).
