BASIC OPERATION

Powering the TRACER

The Tracer uses four CR2032 Lithium Ion batteries. If the batteries are weak,

BAT indicator will appear on the display. Press the ON/OFF key to turn

the

automatically after 10 minutes after the last button push.

Automatic Calibration

When the TRACER is turned on, it will enter the Automatic Calibration

calibration is completed, the

TDS Conversion Ratio

The TDS value is determined by multiplying the conductivity measurement
by a known conversion ratio factor. The meter allows the selection of a
conversion ratio factor in the range of 0.4 to 1.0. The selected ratio will vary
with application but is typically set between 0.5 and 0.7. In the salinity mode,
the ratio is fi xed at 0.5. The stored ratio factor will briefl y appear in the lower
temperature display when the meter is fi rst turned on or when changing the
measurement function to TDS.

To Change the TDS Conversion Ratio:

1. Turn the TRACER on.

2. Press and release the CAL/RECALL button twice.
The stored ratio will appear in the display.

3. Press the MODE/HOLD button to change the ratio
value in steps of 0.1.

4. When the desired ratio is displayed, press and release
the CAL/RECALL button to store the value and return
to the normal mode.

5. If no buttons are pressed for 5 seconds, the meter
will return to the measurement mode.

SELF and CAL display icons will extinguish.

TESTING

Getting Started

1. Remove the cap from the bottom of the TRACER to expose the electrode.

2. Before the fi rst use, rinse the electrode in deionized water and dry.

Changing the Measurement Function

The meter can be set to measure Conductivity, TDS (ppm), TDS (mg/L) or
Salinity (ppm). To change the mode:

1. Turn the TRACER on.

2. Press and hold the MODE/HOLD button for 2 seconds. The display will
begin to scroll through the units.
μS or mS (Conductivity)
ppm (TDS)
ppm (Salinity “S”)

3. Release the MODE/HOLD key when the desired mode is displayed.

4. Note that the “HOLD” function can not be on when changing functions.

Measurement

1. Fill a sample cup to the 20 mL line with the test sample. Sample depth
must be greater than or equal to 1.5 inches.

2. Immerse the TRACER electrode in the sample. Make sure the electrode is
completely submersed.

3. Press the ON/OFF button. (8888 and then SELF CAL
will appear in the display during the initial diagnos­tics).

4. Press and hold the MODE/HOLD button to scroll to
the desired measurement mode.

5. Slowly stir the sample with the TRACER to remove
air bubbles.

the location number (1 through 25) will briefl y appear and then the value
stored in that location will appear. The displayed units will fl ash, indicat-
ing that the storage recall mode is active.

previously stored readings, press the MODE/HOLD button. The location
number is displayed fi rst, followed by the reading stored in that location.

3. To exit the storage mode, press the CAL/RECALL button and the
TRACER will return to normal operation after displaying “End”.

Clearing the Stored Memory

Turn the TRACER on. Press and hold the ON/OFF button for 4 second the display
will briefl y display “clr” when the memory is cleared.

CALIBRATION (SALT/TDS)

For the most accurate results, allow suffi cient time for the temperature of the
probe to reach the temperature of the sample before calibrating. This will be
indicated by a stable temperature reading on the display

Meter accuracy verifi cation should be performed on a periodic/monthly basis
as needed. The frequency of the verifi cation will depend on the storage and

maintenance conditions and amount of meter use. If calibration is required,

the meter must be in the salinity mode to perform calibration for salinity
and TDS. The meter can perform a calibration and store the data. The automatic

calibration recognition procedure will recognize a conductivity standard of
3,000 ppm (3ppt). Always calibrate in the range closest to the expected
measurement value. For salinity samples within the range of 1,000 to 9,999 ppm
salinity, calibrate with a 3,000 ppm calibration standard.

1. Fill a sample cup to 20 mL line with a calibration standard.

2. Press the ON/OFF button to turn the TRACER on. Insert the electrode
into the standard. Tap or stir the sample with the Tracer to dislodge air
bubbles.

3. Press and hold the CAL/RECALL button for approximately 2 seconds.
“CAL” will appear and the display will fl ash.

4. The meter will automatically recognize and calibrate to the calibration
standard. The display will briefl y indicate “SA” and “End” and then return
to the measurement mode.
NOTE: “SA” will not appear if the calibration fails.

5. The calibration range indicator will appear on the display for each range
that is calibrated during a power on cycle.

NOTE: Each time the calibration mode is entered all calibration range indicator
will be cleared, but only the calibration data for the currently selected range will
be replaced.

MAINTENANCE

Care/Storage of Electrode

1. Always rinse the electrode in distilled, tap or deionized water between
measurements to avoid cross contamination. Double rinsing is recommended
when high accuracy is required.

2. Store the electrode dry with the cap on.

3. Do not touch the electrodes. Touching the surface of the platinized
electrodes may damage and reduce the life of the electrodes.

Electrode Cleaning Recommendations

Do not soak the electrode in the solutions for longer than the recommended length
of time. To do so may cause a reference potential shift which will cause a
degradation in performance or failure. When cleaning the probe, do not scratch
or damage the platinized electrode surfaces. To remove water soluble contaminants
from the electrode, soak the electrode in deionized water and scrub with a soft brush.

Battery Replacement

1. Twist off the battery compartment cap.

2. Hold the battery housing in place with one fi nger. Remove the battery
carrier by pulling on the small tabs.

3. Replace the four CR2032 batteries. Observe polarity.

4. Replace the battery compartment cap.

Replacing the electrode

1. Unscrew and remove the electrode collar. Turn collar counter-clockwise.

2. Gently rock the electrode side to side, while pulling it away from the
meter, until it disconnects from the electrode socket.

3. To attach an electrode, align the slots and carefully plug the electrode into
the meter socket. CAUTION: Take care to align pins carefully. Bent or
broken pins will cause the meter to malfunction.

4. Firmly tighten the electrode collar to create a seal with the rubber gasket
between the electrode and the meter.
