5. Alkalinity Calibration
Prepare the materials required for titration: Alkalinity Standard Solution
100PPM, Reagent: A1, cell extender, T-plunger, and 100 µL pipette with
a clean tip installed.
nOte:
If you do not complete each titration point within the 3-minute
timeout period, the unit exits the Alkalinity function. Between titrations,
the unit will automatically power off after the period of inactivity defined
in the AUTO OFF setting (ref. AUTO OFF, pg. 43). Press
alK
to start the
titration process over from step 1.
If you make a gross error in your titration method, e.g., you forget to add
sample to the cell, “
err
” will display. Start the titration over from Step 1
to obtain a reading.
1.
Ensure pH protective cap is secure to avoid contamination.
2.
Install the cell extender by pushing the base of the cell extender
into the conductivity cell until it is fully seated.
3.
Rinse the conductivity cell cup and cell extender 3 times with
Alkalinity Standard 100PPM.
4.
Refill cell cup and cell extender with Alkalinity Standard 100PPM.
5.
Insert T-plunger into open cell extender until the “T” rests flush
on the lip of the cell extender. This will cause fluid beyond what
is required for titration to overflow the cell extender.
6.
Rotate the T-plunger from side to side, allowing the arms of the
T-plunger to slide along the rim of
the cell extender.
7.
Carefully remove the T-plunger so as not to flick or spill remaining
sample. Tap the T-plunger on the side of the cell extender to
remove sample that may be stuck to the T-plunger.
