1. Press .

2. Press repeatedly until “tc On” is displayed

(see Figures 10 and 11).

3. Press ; the display will change to “tc OFF”.

4. Press ; all conductivity and TDS measurements are now

uncompensated.

Repeat steps 1-4 to reverse selection back to “tc On”.

XII. SALINITY UNITS (TPH1 & TP1)

“Salinity” Units may be selected in either COND or TDS mode, and in

ANY solution KCl, NaCl & 442. TDS 442 shown below, (ref. Solution

Selection, pg. 9).

Salinity (S) - A parameter used in oceanography to describe the

concentration of dissolved salts in seawater. It is dened in terms of

electrical conductivity relative to a standard solution of KCl.

When expressed in units of parts per thousand, the salinity may be

roughly equated to the concentration of dissolved material in grams per

kilogram (grams/liter) of seawater (NaCl). HC&P 85th edition 2-55

Since most applications do not use seawater, which is predominately

Sodium Chloride (NaCl), we highly recommend the solution of choice be

442™. 442 more closely matches the fresh natural water used in most

applications (ref. Conductivity/TDS Standard Solutions, pg. 24).
