2. COND, RES 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 or User),
refer to Why Solution Selection is Available, pg. 22 and
Procedure to Select a Solution, pg. 23.
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. RES Key
A press of displays resistivity with units on the right. On the left
is shown solution type selected for resistivity (ref. Solution Selection,
pg. 22). The range of display of resistivity is limited to between 10
kilohms (KΩ) and 30 megohms (MΩ). A solution outside that range will
only 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. 22).
3. Alkalinity, Hardness and LSI Keys
These 3 keys enter the unit 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 unit in the Hardness titration function.
c. LSI Key
A press of enters the unit 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.
