4.3 Calibration

procedure

4.3.1

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

If necessary, press the MODE key to select

COND mode. The

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.

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.

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

key for CON 10, or MI/

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).
