Sample measurement
Before measurement:
The probe must have the correct service-life time stamp. Set the date and time in the meter before the probe is attached.
If complete traceability is necessary, enter a sample ID and operator ID before measurement. Refer to the HQd meter
manual for more information.
To display other parameters (TDS, salinity or resistivity), push , select CDC401 Settings and then Current Method.
When using the CDC401 probe with the LDO101 probe to do auto salinity correction, set the CDC401 probe to measure
salinity. Refer to
Regular calibration is required for the best measurement accuracy (refer to
on page 2).
If a rugged probe, make sure that the shroud is installed. Damage to the sensing elements can occur if the shroud is not
installed during field use. Damage under these conditions is not covered by the product warranty.
To deploy a rugged probe at a distance, toss the probe body with a gentle underhand throw. Do not swing the probe by the
cable as this may cause injury to the user, will cause severe strain on the cable and will shorten the service life of the probe.
Measurement notes:
•
Do not touch the tip of the probe.
•
Stabilization times with smaller concentration changes generally will be longer and
can be minimized by correct stirring and conditioning. Experiment to determine the
correct stir rate if necessary.
•
Data is automatically stored in the data log when Press to Read or Interval is
selected in the Measurement Mode. When Continuous is selected, data will only be
stored when Store is selected.
•
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 measurement error occurs, refer to
on page 9.
Measurement procedure:
Note: Procedure also applies for rugged model probes.
1. Connect the
probe to the
meter. Make sure
that the cable
locking nut is
securely
connected to the
meter. Turn on the
meter.
2. Rinse the
probe with
deionized water.
Blot dry with a lint-
free cloth.
3. Put the probe
into the sample so
that the
temperature
sensor is
completely
submerged. Do
not put the probe
on the bottom or
sides of the
container.
4. Push Read.
The display will
show "Stabilizing"
and a progress
bar as the probe
stabilizes in the
sample. The
display will show
the lock icon when
the reading
stabilizes. The
measurement is
automatically
corrected to the
selected reference
temperature (20 or
25 °C).
5. Repeat steps
2 - 4 for additional
measurements.
When
measurements
are done, store
the probe (refer to
on page 9).
