Conductivity Operation: Standardizing
PC6000, CON6000, PC6500 and PCD6500 meters
Technology Made Easy ...
To Standardize the meter with Auto Standard Recognition (Conductivity mode only)
1. Touch Standardize on the conductivity measure screen to access the standardize
screen.
2. If the screen says “Not standardized” proceed to step 4.
3. Touch Clear if you need to delete the previous standardization values
4. Immerse your rinsed conductivity cell in a standard solution (84 uS, 1.413 ms, 12.88 mS
or 111.8 mS) and stir gently. The immersion depth should be enough to cover the vent
holes on the electrode.
5. The screen will flash a beaker icon of the standard solution you have selected. When the
reading is stable, STABLE appears on the screen. Touch Confirm to standardize the
buffer. The meter will then return to the conductivity measure screen.
6. If you selected Single Point in the Setup mode Calibration Point(s), your meter is now
ready to measure conductivity with one standardization factor.
OR
If you selected Multi Point in the Setup mode Calibration Point(s), touch Standardize on
the conductivity measure screen to access the standardization screen and repeat steps 4
through 6 to standardize with up to 4 points. Performing a multi point calibration will give
your meter multiple standardization factors.
Once meter is calibrated, the conductivity
Measure screen shows the standards and
the time/date of last standardization. Conductivity standardization with Auto
standard recognition (available in
