SOLUTION SELECTION
A. Why Solution Selection is Available
Conductivity, MIN/SALT, and TDS require temperature correction to
25°C values (ref. Standardized to 25°C, pg. 33). Selection determines
the temperature correction of conductivity and calculation of TDS from
compensated conductivity (ref. Cond. Conversion to TDS, pg. 36).
B. The 3 Solution Types
On the left side of the display is the salt solution characteristic used
to model temperature compensation of conductivity and its TDS
conversion. Generally, using KCl for Conductivity, NaCl for Mineral/
Salt, and 442 (Natural Water characteristic) for TDS will reflect present
industry practice for standardization. This is the setup as shipped from
the factory (ref. Solution Characteristics, pg. 36).
C. Calibration of Each Solution Type
There is a separate calibration for each of the 3 solution types. Note
that calibration of a 442 solution does not affect the calibration of a NaCl
solution. For example: Calibration (ref. Conductivity or TDS Calibration,
pg. 13) is performed separately for each type of solution one wishes to
measure (ref. Conductivity/TDS Standard Solutions, pg. 32).
D. Procedure to Select a Solution
NOTE: Check display to see if solution displayed (KCl, NaCl, 442) is
already the type desired. If not:
1.
Press , or to select the parameter on
which you wish to change the
solution type.
2.
Press and hold key
for 3 seconds to make
“SEL” appear (see Figure 1).
(For demonstration purposes,
all 3 solution types are shown simultaneously.)
3.
Use the or key to select type of solution desired
(ref. Solution Characteristics, pg. 36). The selected solution
type will be displayed: KCl, NaCl, or 442.
4.
Press to accept new solution type.
