5.4 Setting the TDS Factor ( TDS 6 PLUS only)
As the concentration of salts dissolved in solution increases, the
conductivity will increase. This relationship varies from salt to salt and
is roughly linear over a given range for a given salt. The TDS conversion
factor is the number used by the meter to convert from conductivity to
TDS.
The TDS conversion factor can be set from 0.4 to 1.0. The default value
is 0.5.
See Section
13 – Calculating TDS Conversion Factor .
1. Enter advanced setup as described in Section
5.1.
2. Press or until [ tdS ] appears. Press
ENTER .
3. Press or to select the desired TDS
factor.
4. Press ENTER to select and return to the [ tdS ]
setup function.
5. Press or to move to the next setup
function or press CAL to exit to the
measurement mode.
5.5 Temperature Coefficient
The temperature coe ffi cient is the amount of change
in conductivity per degree temperature (% per °C). For best results,
determine and enter the exact temperature coe ffi cient of the solution. The
meter will allow values from 0.0 to 3.0 % per °C. The default value is 2.1
% per °C.
Note: Select 0.0% for uncompensated measurements. The temperature
will be measured by the probe and displayed.
See Section
14 – Calculating Temperature Coe ffi cients .
1. Enter advanced setup as described in Section
5.1.
2. Press or until [ t.Co % ] appears. Press
ENTER .
3. Press or to select a value between 0.0 to
3.0%.
4. Press ENTER key to select and return to the
[ t.Co % ] setup function.
