Product overview
The CDC401 series probe is a graphite, 4-pole conductivity probe (Figure 1). The
CDC40101 or CDC40103 standard conductivity probe is available with a 1 or 3 m (3.28 or
9.84 ft) cable and is intended for laboratory use. The CDC40105, CDC40110,
CDC40115 or CDC40130 rugged conductivity probe is available with a 5, 10, 15 or 30 m
(16.40, 32.81, 49.21 or 98.42 ft) cable. The probe measures electrical conductivity,
salinity, resistivity or total dissolved solids (TDS) in wastewater, drinking water and
general applications.

Calibration
Before calibration:
The probe must have the correct service-life time stamp. Set the date and time in the meter before the probe is attached.
It is not necessary to recalibrate when moving a calibrated probe from one HQd meter to another if the additional meter is
configured to use the same calibration options.
To view the current calibration, push , select View Probe Data, then select View Current Calibration.
If any two probes are connected, push the UP or DOWN arrow to change to the single display mode in order to show the
Calibrate option.
If a rugged probe, remove the shroud from the probe (refer to Remove the shroud
Calibration notes:
Do not touch the tip of the probe.
•
• Additional conductivity standards can be selected in the Calibration Options menu.
• The cell constant is derived from the calibration standard.
• Do not dilute conductivity standards and samples.
on page 8).

• The meter will automatically correct the calibration measurement to the selected
reference temperature (20 or 25 °C) using the default NaCl-based, non-linear
temperature coefficient. Settings can be changed in the CDC401 Calibration Options
menu.
The calibration is recorded in the probe and the data log. The calibration is also sent
•
to a PC, printer or flash memory stick if connected.
• Air bubbles under the sensor tip when submerged can cause slow response or error
in measurement. If bubbles are present, gently shake the probe until bubbles are
removed.
• If a calibration error occurs, refer to Troubleshooting on page 9.
Calibration procedure:
1. Connect the
probe to the
meter. Make sure
that the cable
locking nut is
securely
connected to the
meter. Turn on the
meter.
6. Push Read.
Stir gently. The
display will show
"Stabilizing" and a
progress bar as
the probe
stabilizes in the
standard. The
display shows the
standard solution
value that has just
been read and
shows the
temperature
corrected value
when the reading
is stable.
2. Push
Calibrate. The
display shows the
conductivity
standard solution
that is necessary
for calibration.
7. Push Done to
view the
calibration
summary.
3. Add fresh
conductivity
standard solution
to a beaker or an
appropriate
container.
8. Push Store to
accept the
calibration and
return to the
measurement
mode. If a rugged
probe, install the
shroud on the
probe (refer to
Install the shroud
on page
9).
4. Rinse the
probe with
deionized water.
Blot dry with a lintfree cloth.
5. Put the probe
in the standard
solution and stir
gently. Make sure
that the
temperature
sensor is
completely
submerged.
