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).
