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.
