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.
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 inside rim of the cell extender
to remove sample that may be stuck to the T-plunger.
8. Press . “AL” alternating with “tdS” briefly displays along
with the “PPM” value of the sample. “P
r
ES CAL” will display
when the reading stabilizes.
9. Press CAL to accept and advance to the first titration prompt.
“Add” alternating with “A1” displays.
10. Using the pipette, add 100µL of Reagent: A1, close the cell
extender cap securely, Press CAL to continue.
11. “AGit t1” flashes on the screen. Agitate to mix the sample. When
agitation is done, tap the cell extender cap to dispel any solution
clinging to the cap back into the cell. Press CAL to continue.
