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 CDC401-05, CDC401-10, CDC401-15, or CDC401-30 Probe, which is

equipped with a bell-and-ring shroud. The probe can be equipped with a 5-, 10-, 15-, or
30-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.

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

Optional probe-cable depth markers are available (Cat. No. 58286-10).

Maintenance

Important Note: Do not remove the cable from the electrode. Doing so can damage the
probe.

Important Note: To ensure accurate temperature readings, do not cover the temperature
sensor with the shroud.

1. Attach a pair of color-code clips to the electrode and cable connector
(Figure 1, item 3).

2. Rinse the 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 and make sure the instrument is properly
grounded.

Storage

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