BASIC OPERATION
Powering the TRACER
The Tracer uses four CR 2032 Lithium Ion batteries. If the batteries are
weak, the BAT indicator will appear on the display. Press the ON/OFF
button to turn the TRACER on or off. The auto power off feature will
shut the TRACER off automatically after 10 minutes after the last
button push.
Automatic Calibration
When the TRACER is turned on, it will enter the Automatic
Calibration mode. SELF and CAL will appear while the calibration is in
progress. After the calibration is completed, the SELF and CAL display
icons will extinguish.
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 fixed at 0.5. The stored ratio
factor will briefly appear in the lower temperature display when the
meter is first turned on or when changing the measurement function to
TDS.
To change the ratio while in the TDS measurement mode:
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.

TESTING
Getting Started
1. Remove the cap from the bottom of the TRACER to expose the pH
electrode, reference junction and the conductivity electrodes.
2. Before the first use or after storage, soak the electrode in tap water or
pH 4 buffer for 10 minutes.
3. White KCL crystals may be present in the cap or on the electrode.
This is to be expected if the TRACER has been stored for any
length of time. The crystals will dissolve with soaking or they can be
rinsed off with tap water.
4. Calibrate with pH 7 buffer prior to the first use or after prolonged
storage.
5. When the meter is calibrated for conductivity, salinity or TDS the
meter must be in the conductivity mode. See page 15.
Changing the Measurement Function
The meter can be set to measure Conductivity, pH, Salinity (ppm),
TDS(ppm), or TDS (mg/L). 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)

MEASUREMENT PROCEDURE
Measurement
1. For small samples 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. pH can also
be measured by contact of the electrode
tip with a wet surface. For larger samples,

3. Press and hold the MODE/HOLD button
to scroll to the desired measurement
mode.
4. Immerse the TRACER electrode in the sample.
Make sure the electrode is completly submersed.
5. Slowly stir the sample with the TRACER to
remove air bubbles if in the Conductivity,
TDS or Salinity mode.
6. If the TRACER is in the Conductivity, TDS,
or Salinity mode, the meter will automatically
auto-range to the proper range and then display

the reading.The display will flash “0000” while
autoranging.
7. If the TRACER is in the pH mode, the reading
will flash until it has stabilized. This may take
several seconds depending on the buffer capacity
of the sample.
8. Rinse the electrode in distilled water. Replace
the cap.
NOTE: 1 part per thousand (ppt) equals 1000 parts per million (ppm).
Example: 3.1ppt=3,100 ppm
11
NOTE: When measuring samples with low conductivity, thoroughly
rinse the probe with distilled or deionized water before placing it in the
sample to avoid contamination of the sample with electrolyte from the
pH reference electrode. Also increase the sample size to 200 to 500 mL
to decrease the chance of contamination. If a sample cup is used, do not
allow the probe to sit in the sample for any longer than necessary to
avoid electrolyte leakage into the sample. Leakage will raise the
conductivity level.
Measuring the TDS of Soil
1. Fill a 50 mL beaker with the soil sample. Tap the beaker lightly on a
hard surface to remove trapped air. Remove excess soil from the
surface.
2. Empty the soil into a 250 mL wide-mouth flask.
3. Add 100 mL of distilled water. Stopper and shake vigorously.
4. Wait 30 minute. (Shake the flask vigorously three or four times
during this period.)
5. Filter the contents of the flask. Collect the filtrate in a beaker.
6. Rinse the electrode with distilled or deionized water to remove
impurities.
7. Press the ON/OFF button to turn the TRACER on. Make sure the
meter is in the TDS mode.
8. Immerse the electrode in the filtrate. Make sure the tip of the
electrode is completely immersed.
9. Stir the filtrate with the electrode to create a homogeneous solution.
10. Gently stir the filtrate with the electrode. Read the TDS value of
the filtrate from the display.
11. Rinse the electrode in distilled water. Replace the cap.
12
Storing Readings
1. After the reading is displayed press and hold the MODE/HOLD
button to store the current reading. The
meter will enter the HOLD mode and HOLD
will be displayed. The storage location
number (1 through 25) will be displayed on
the lower display followed by the reading
being stored.
2. Press the MODE/HOLD button to exit the
HOLD mode and return to normal operation.
3. If an attempt is made to store more than 25
readings, the stored readings will be
overwritten starting with the first reading.
Recalling Stored Readings
NOTE: First ensure that the HOLD symbol is not displayed. If it is, exit
the HOLD function by pressing the MODE/HOLD button.
1. Press the CAL/RECALL button and then press the MODE/HOLD
button. The location number (1 through 25) will briefly appear and
then the value stored in that location will appear. The displayed
units will flash, indicating that the storage recall mode is active.
2. The last stored reading taken will be displayed first. To advance to
the previously stored readings, press the MODE/HOLD button. The
location number is displayed first, 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 Stored Memory
Turn the TRACER on. Press and hold the ON/OFF button for 4
seconds. The display will briefly display “clr” when the memory is
cleared.
1313
CALIBRATION
For the most accurate results, allow sufficient 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.
pH
The TRACER can be calibrated at 1, 2 or 3 points. For the most
accurate results with a two point calibration, calibrate the TRACER
with a pH 7 buffer first, then calibrate with either a pH 4 or pH 10
buffer whichever is closest to the pH value of the sample to be tested.
When performing a three point calibration, calibrate with the pH 7
buffer first, followed with the pH 4 buffer and then the pH 10 buffer.
Preparation of Buffers
1. Fill a sample cup with 20 mL of distilled or deionized water.
2. Add one buffer tablet:
pH 4.0 Code 3983A
pH 7.0 Code 3984A
pH 10.0 Code 3985A
3. Use the tablet crusher (0175) to crush the tablet. Stir until the
tablet has disintegrated.
NOTE: Buffers should be prepared fresh daily.
Calibration
1. Fill a sample cup to the 20 mL line with a buffer solution.
2. Press the ON/OFF button to turn the TRACER ON.
3. Place the electrode in the buffer solution. Press and hold the
CAL/RECALL button until “CAL” appears in the lower display.
The meter will automatically recognize the buffer and calibrate itself
to that value. The circled number on the display will match the
value of the buffer.
NOTE: If the buffer solution is more than 1 pH unit off from 4, 7,
or 10, or the electrode slope is low,the meter will assume that there
is an error and the calibration will be terminated. END will be
displayed.
4. During the calibration the pH value on the display will flash. When
the calibration is complete, the TRACER will display “SA” and
“End” and return to normal operation.
5. The appropriately circled indicator (L, M or H) will appear on the
display when a calibration has been completed within one power on
cycle.
14
6. For a two or three point calibration, repeat steps1–5with the
remaining buffers.
7. When the TRACER is turned off, the circled indicator
configuration and the calibration data will be memorized.
Calibration Reminder
The “CAL” indicator will appear when the TRACER is in the pH mode
and a calibration is required. The “CAL” indicator will appear if the
meter has not been calibrated after 15 on/off cycles of the meter. Some
applications may require more frequent calibrations than others. The
“CAL” indicator is only a reminder and will not affect function in any
way. The indicator will no longer be displayed when the pH electrode is
recalibrated.
RENEW Indicator
A flashing “RENEW” indicator will appear on the display to warn that
the electrode is not performing to expected specifications. If cleaning or
recalibration does not cause the RENEW indicator to disappear, the
electrode should be replaced. The RENEW indicator will appear when
the pH electrode slope falls below 70% of a nominal slope.
Conductivity
Meter accuracy verification should be performed on a periodic basis as
needed. If calibration is required, the meter must be in the
conductivity mode to perform all calibrations for conductivity, TDS
and salinity. The meter can perform a calibrations and store the data for
each of the three ranges – low, medium and high. The automatic
calibration recognition procedure will recognize conductivity standards
of 84µS (Low), 1413µS (Medium) or 12,880µS (12.88mS) (High). (See
Page 6). Always calibrate in the range closest to the expected
measurement value. For salinity samples within the range of 1.00 to
9.99 ppt salinity, calibrate with a 12,880µS calibration standard.
1. Fill a sample cup to 20 mL line with a conductivity standard.
NOTE: The meter allows for a 1, 2, or 3 point calibration. If
calibration is done for more than one point, the lowest
concentration should be done first to obtain the best accuracy.
Calibrate the ranges from low to high
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 until the display begins to flash.
15
4. The meter will automatically recognize and calibrate to the
conductivity standard. The display will briefly 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.
Low Range, 84 µS/cm
L
Medium Range, 1413 µS/cm
M
High Range, 12.88 mS/cm (12,880 µS/cm)
H
NOTE: Each time the calibration mode is entered all calibration
range indicators will be cleared, but only the calibration data for the
currently selected range will be replaced. The calibrations for the
other two ranges will be saved even though the indicators for those
ranges are no longer displayed. Calibration of all three ranges must
be performed during one power on period for all three calibration
range indicators to be displayed.
NOTE: As with all combination pH/conductivity probes, at low
conductivity levels the flow of the pH electrolyte may affect the
readings and result in artificially high conductivity readings. To
eliminate the interference, low level conductivity or TDS
measurements should be taken with a meter that measures
conductivity only.

MAINTENANCE
Storage
1. Rinse the electrode in distilled or deionized water.
2. Store the electrode with the cap on. Keep the sponge in the cap
soaked with tap water or pH 4 buffer solution.
3. Always rinse the electrode in deionized water between
measurements to avoid cross contamination. Double rinsing is
recommended when high accuracy is required.
4. Salt deposits may build up in the storage cap and should periodically
be rinsed away. These deposits could affect measurements at low
conductivity.
Battery Replacement
1. Twist off the battery compartment cap.
2. Hold the battery housing in place with one finger. Remove the
battery carrier by pulling on the small tabs.
3. Replace the four CR2032 batteries. Observe polarity.
4. Replace the battery compartment cap.
Electrode Care
1. Always rinse the electrode in distilled or deionized water between
measurements to avoid cross-contamination of the samples. Double
rinsing is recommended when high accuracy is required.
2. Do not touch the electrodes. Touching the surface of the platinized
electrodes may damage and reduce the life of the electrodes.
19
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.
4. Firmly tighten the electrode collar to create a seal with the rubber
gasket between the electrode and the meter.
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 electrode, take care not to scratch or damage the sensing
surface or the platinized electrode surfaces.
