compensated conductivity (ref. Cond. Conversion to TDS, pg. 59).
B. The 4 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 resistivity, and 442 (Natural
Water characteristic) for TDS will reflect present industry practice for
standardization. This is how your instrument is shipped from the factory
(ref. Solution Characteristics, pg. 59).
The User selection allows a custom value to be entered for the
temperature compensation of conductivity and also the conversion ratio
if measuring TDS.
C. Calibration of Each Solution Type
There is a separate calibration for each of the 4 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. 27) is performed separately for each type of solution one wishes to
measure (ref. Conductivity/TDS Standard Solutions, pg. 54).
D. Procedure to Select a Solution
nOte: Check display to see if solution displayed (KCl, NaCl, 442 or
User) 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 4
solution types are shown simultaneously.
3. Use the or key to select type of solution desired
(ref. Solution Characteristics, pg. 59). The selected solution
type will be displayed: KCl, NaCl, 442 or User.
4. Press to accept new solution type.
