4.4 Automatic
Calibration
(Conductivity)
In the Automatic Calibration mode, the meter is capable of accepting either
single-point or up to 4 points for multi-point calibration with maximum of 1 point
per specific measurement range. For the known calibration standard values
refer to
Table 1 in Section 4.3
.
1) If necessary, press
MODE
key to select
conductivity mode.
2)
Rinse the probe thoroughly with de-ionized
water or a rinse solution, then rinse with a
small amount of calibration standard.
NOTE: For Automatic Calibration you must use
one of the calibration standards listed in
Table 1.
3)
Dip the probe into the calibration standard.
Immerse the probe tip beyond the upper steel
band (
see Figure in Section 3.4
). Stir the probe
gently to create a homogeneous sample. Allow
time for the reading to stabilize.
4) Press
CAL
key to enter conductivity calibration
mode. The [
CA
] indicator will appear for 1.5
seconds, and a value will appear flashing.
NOTE: To exit calibration without confirmation,
press CAL key again to go back to
measurement mode.
5)
Wait for the value to stabilize and press
ENTER
key. The calibration standard value
will appear for 3 seconds. If the calibration is
successfully performed, a [
donE
] will be
displayed for about 3 seconds, and the meter
returns to measurement mode.
6)
To perform the next point calibration in the
multi-point calibration, repeat step 1-5 again
until all points have been calibrated if necessary.
