Conductivity Operation:
Standardizing
XL20, 30, 50 and 60 meters
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.
