Operator Manual Anatel
9.3.2.3 Conductivity/ Resistivity Output
Defaults: Zero-Scale – 00 µS/cm
Full-Scale – 20 µS/cm
The DAC Zero-Scale and Full-Scale settings define the upper and lower limits that are
proportional to the DAC mA Range setting. The analog signal is converted to a scaled
conductivity or resistivity value for output, depending on the selected Display Units setting
(see “Display Units” on page 56).
To set the output range:
1) With the DAC Range Menu displayed, use the Up and Down Keys to specify DAC
Zero-Scale.
2) Press Enter to display its menu selections.
3) Specify Res/Cond DAC and press Enter to display its zero-scale parameter screen.
The units reflect the Resis/Cond parameter selection, displayed in uS/cm for
conductivity or MΩ-cm for resistivity. If either unit is followed by a U, it indicates that the
reading is uncompensated.
