Safety

To ensure that the protection provided by this equipment is not impaired, do not use or install
this equipment in any manner other than that specified in this document.

This symbol, if noted on the instrument, references the instruction manual for operation and/or safety information.

Electrical equipment marked with this symbol may not be disposed of in European public disposal systems after 12
August of 2005. In conformity with European local and national regulations (EU Directive 2002/96/EC), European
electrical equipment users must now return old or end-of life equipment to the Producer for disposal at no charge to
the user.

Note: For return for recycling, please contact the equipment producer or supplier for instructions on how to return
end-of-life equipment, producer-supplied electrical accessories, and all auxiliary items for proper disposal.

Overview

Figure 1shows the CDC401-01 or CDC401-03 Probe, a 4-pole conductivity probe, equipped

with either a 1- or 3-meter cable. The probe is designed for fast, accurate measurement of
conductivity, salinity, resistivity, or total dissolved solids (TDS) in wastewater, drinking water,
and general applications.

4-pole Conductivity Sensor

2 Color-coded clip locations

Each electrode is supplied with color-code clips for easy identification. There are two each of
five colors (black, yellow, light green, light blue, and magenta), one for the electrode and one
for the cable connector.

Specifications

1. Attach a pair of color-code clips to the electrode and cable connector (Figure 1, item 2).

2. Rinse probe with deionized water prior to use.

For calibration steps, refer to the HQ Portable Meters User Manual. The IntelliCAL™ probes
store the current calibration and calibration history in the probe memory. It is not necessary to
recalibrate when moving a calibrated electrode from one meter to another.

General Maintenance

• Between samples, wipe the probe with a clean towel.

• If the connection to the meter is poor, readings may be unstable. To ensure accurate

readings, check the connection to the meter.

Storage

• Between uses, store the probe dry in ambient conditions.
