unit as prompted, then pressing
cal
as prompted. An alkalinity
value will display when the titration measurement is complete.
14.
Note the value for your records or press
ms
to store the value.
You can begin another Alkalinity titration by pressing
alK
.
The unit will automatically power off after the period of inactivity
defined in the AUTO OFF setting (ref. AUTO OFF, pg. 43).

Measuring Hardness
1.
Hardness Unit Selection
The 9P offers the ability to set the hardness unit preference to either
“
PPm
” CaCO
3
or grains of hardness.
To change hardness units, press
harD
, then press and hold
cal
down until
“
hard
”
and
“
sel
”
are
displayed. Press
UP
or
DOwn
to toggle between “
PPm
” and grains
(no units are displayed for grains). Press
cal
to accept. This also sets
the hardness unit preference for the LSI Titration function and the LSI
Calculator simultaneously.

Hardness Titration Procedure
Prepare the materials required for titration: Reagent: C1, Reagent: H1,
Reagent: H2, Reagent: H3, cell extender, T-plunger, 100 µL pipette with
a clean tip installed, and two extra clean tips.
nOte:
If you do not complete each titration point within the 3-minute
timeout period, the unit exits the Hardness function. Press
harD
to
start the titration process over from step 1. Between titrations, the unit
will automatically power off after the period of inactivity defined in the
AUTO OFF setting (ref. AUTO OFF, pg. 43).
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
solution to be measured.
4.
Refill cell cup and cell extender with sample solution.
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.
