2. COND, MIN/SALT and TDS Keys
These 3 keys are used with solution in the Conductivity Cell.
Precautions:
• While filling cell cup, ensure no air bubbles cling on the cell
wall.
• If the proper solution is not selected (KCl, NaCl, 442), refer to
Why Solution Selection is Available, pg. 24 and Procedure to
Select a Solution, pg. 25.
a. COND Key
Solution to be tested is introduced into the conductivity cell and a press
of
displays conductivity with units on the right. On the left is
shown the solution type selected for conductivity.
b. MIN/SALT Key
A press of
MIN
SALT
displays Mineral/Salt concentration with PPM or
PPT units on the right. On the left the NaCl solution type is shown. An
overrange condition will show [- - - -] in the display.
c. TDS Key
A press of displays Total Dissolved Solids with units on the right.
This is a display of the concentration of ionized material calculated from
compensated conductivity using the characteristics of a known material.
On the left is shown solution type selected for TDS (ref. Solution
Selection, pg. 24).
3. Alkalinity, Hardness and LSI Keys
These 3 keys enter the PS9 in the titration measurement functions. The
LSI key also allows you to access the LSI Calculator.
nOTE: All titration measurements require the installation of the cell
extender.
a. Alkalinity Key
A press of enters the Alkalinity titration function.
b. Hardness Key
A press of enters the PS9 in the Hardness titration function.
c. LSI Key
A press of enters the PS9 in LSI calculator mode, which can be
used to measure LSI by pulling the most recent alkalinity, hardness, pH
and temperature values or for hypothetical water balance adjustments.
