Change measurement options
Methods are groups of default or user-defined settings relevant to specific applications. If
the meter is set to the default method and the Modify Current Settings option is chosen, a
prompt for a new name is shown after the changes are entered. The settings are saved
with this name to distinguish them from the default method settings, which cannot be
changed. A saved method can be used instead of multiple adjustments to the individual
settings. Changes made to a user defined method are automatically saved with the
existing name. Multiple methods can be saved for the same probe on each meter.
Table 2 lists the five default methods available for the CDC401 conductivity cell.
Table 2 Default methods
Options Description
Hach Conductivity Default method with conductivity measurement values.
Conductivity is typically used for natural water samples.
Hach TDS Default method with TDS measurement values. TDS is typically used to estimate the amount of total
dissolved solids in the sample. The conductivity value is also shown in the Detailed Reading screen.
Hach Salinity Default method with salinity measurement values. Salinity is typically used for samples with a high salt
content, such as sea water. The conductivity value will also be shown in the Detailed Reading screen.
Hach Resistivity Default method with resistivity measurement values. Resistivity is typically used for ultra pure water
applications.
Default —
1. Make sure a probe is connected to the meter.
2. Push and select CDC401 Settings.
3. Select Modify Current Settings.
4. Select Parameter to change the parameter that is shown in the display.
5. Select Measurement Options and update the settings:
Option Description
Units—
Conductivity Sets the units for conductivity—Auto (default), μS/cm or mS/cm.
When Auto is selected, the units will automatically change to mS/cm
when the sample conductivity is high and μS/cm when the conductivity is
low. Select μS/cm or mS/cm to always show the same units.
Units—Salinity Sets the units for salinity—‰ (default), g/kg, <unitless> or ppt (parts per
thousand).
