BASIC OPERATION
Powering the TRACER
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 of inactivity.
Automatic Electrode Recognition
When the TRACER is turned on, it will recognize the type of electrode that
is connected and will display the appropriate unit of measure. An electrode
must be attached before turning the meter on.
Changing the Displayed Temperature Units
Press and hold the CAL button for approximately 3 seconds. The °C or °F icon
will change first and the numerical temperature value will change only after
the button is released.
NOTE: If the calibration mode is accidentally accessed and CAL appears on
the display, turn the TRACER off and begin again.
Data Hold
Press the MODE button to freeze the current reading. The HOLD display icon
will appear along with the held reading. The held reading will be stored in
memory. Press the MODE button to return to normal operation.
DISPLAY MESSAGES
CAL Reminder
When the TRACER is turned on for the 15th time, without recalibration the
CAL icon will appear on the display indicating the the TRACER may require
calibration. Some applications may require recalibration of the electrode
sooner than others. The CAL display is a reminder and will turn off when the
pH electrode is recalibrated.
RENEW
A flashing “RENEW” warning indicates that the probe may be nearing the end
of its useful life. If cleaning or recalibration does not cause the Renew icon
to disappear, replace the electrode (see optional accessories). The Renew
display appears when the output of the pH electrode fails a diagnostic test.

pH TESTING
Overview
pH is a unit of measure (ranging from 0 to 14 pH) indicating the degree of
acidity or alkalinity of a solution. pH tests are the most commonly performed
measurements in water analysis, using the negative log of the hydrogen ion
activity of a solution which is an indicator of acidity or alkalinity. Solutions
with a pH of less than 7 are considered acidic, solutions with a pH of
higher than 7 are known as bases, and solutions with a pH of exactly 7 are
considered neutral.
The pH scale is logarithmic, so, for example, if Sample A is 1 pH less than
Sample B, this means that sample A is 10 times more acidic than Sample B.
A difference of 1 pH represents a ten-fold increase or decrease in acidity.
pH Display
When the electrode is placed in a solution, the main display and bar graph
will indicate the pH reading while the lower display will read temperature.
Readings flash until they have stabilized. The bar graph is ‘center zero’, i.e. at
pH 7 there is no display. As the pH rises, the bar will move from the center to
the right. If the pH drops, the bar will move from the center to the left.
Getting Started
1. Remove the cap from the bottom of the TRACER to expose the
electrode glass surface and reference junction.
2. Before first use or after storage, soak the electrode (with cap
removed) in a pH 4 buffer or tap water for 10 minutes.
3. Before first use, hold the meter by the top battery compartment
and swiftly tap the back of the meter downward into your palm (not
a hard surface). This assures that the internal electrolyte solution
moves to the very tip of the electrode. The electrolyte should fill the
circular junction window at the tip of the electrode.
4. White KCl crystals may be present in the cap. These crystals will
dissolve in the soak or they can be rinsed off with tap water.
5. Always calibrate close to the expected measurement value.
6. A sponge is located in the electrode protective cap. Keep this sponge
soaked with a pH 4 solution to prolong the life of the electrode during
storage.

8
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.
pH Calibration
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. For the most accurate results, always calibrate at
the sample temperature.
1. Place the electrode into a buffer solution (4, 7, or 10 pH) and press
the CAL button. Typically, pH 7 is calibrated first, then 4 or 10,
depending on the measurement range. If readings are going to be
made over the entire range, calibrate with 4, 7 and 10 buffers.
2. The TRACER will automatically recognize the solution and calibrate
itself to that value. The circled number on the display will match the
pH of the buffer.
Note that if the buffer is more than 1 pH unit off from the 4, 7, or 10
pH buffer, the TRACER will assume an error and abort the calibration.
CAL and END will be displayed.
3. During calibration, the pH reading will flash on the main display.
4. When calibration is complete, the TRACER will automatically display
END and return to the pH measurement mode.
5. Rinse the electrode with distilled water.
6. The appropriate circled indicator (4, 7, or 10) will appear on the
display when a calibration has been completed. The calibration will be
stored until a new calibration is performed.
7. For a two- or three-point calibration, repeat Steps 1-5.
8. The meter should be calibrated before each use to obtain the most
accurate results.

9
9. Always turn the meter off and then on before calibrating to allow
sufficient
time to complete the calibrations during one power cycle. If
the meter auto powers off during calibration the calibrations remain
valid, but new calibrations will turn the circled indicators off.
Meter Reset
If the meter will not calibrate or displays a -1, reset the meter and attempt
to re-calibrate.
1. Turn off the meter.
2. Remove the battery cartridge from the top of the meter.
3. Press the ON/OFF button for 10 seconds to bleed off all charges
within the meter.
4. Re-insert the batteries and turn the meter on.
5. Follow the pH Calibration procedure.
pH Measurement
1. Place the electrode in the test sample.
2. Record the pH after the reading becomes stable and the display
stops flashing.
3. Press the ON/OFF button to turn the meter off. Rinse the electrode
with distilled water. Replace cap
pH Measurement of Soil
1. Place a 1:1 ratio of soil and distilled water in a small beaker. For most
analyses, 20 grams of soil and 20 grams distilled water are sufficient.
2. Wait 15 minutes. Stir occasionally with a stirring rod.
3. Stir the sample. Immediately place the electrode in the sample.
4. Wait until the display stabilizes. Record the pH.
5. Rinse the electrode in distilled water. Replace cap.
NOTE: The flat surface electrode will allow for readings directly from the soil
if there is enough moisture present in the soil.
Storing Readings
1. After the reading is made press the
MODE button to store the current
reading The storage location number
will be displayed followed by the
reading being stored.

2. Press the MODE button to return to normal operation.
3. Repeat step 1 to store the next reading.
4. If an attempt is made to store more than 15 readings, the stored
readings (starting with the first reading) will be overwritten.
Recalling Stored Readings
NOTE: First ensure that the HOLD symbol is not displayed. If it is, exit the
MODE function by pressing the MODE button.
1. Press the CAL button once and then press the MODE button
immediately after CAL is displayed; the location number (1 through
15) will flash. If the CAL mode is accidentally accessed (display
flashing), press the CAL button again to exit.
2. The last stored reading taken will be displayed first. To advance
through the stored readings, press the MODE button. The location
number is displayed first, followed by the reading stored in that
location.
3. To exit the recall mode, press the CAL button and the TRACER will
return to normal operation. If the batteries are removed, any stored
readings and user calibrations will be discarded.
MAINTENANCE
Care/Storage of Electrode
1. Always rinse the electrode in tap, distilled or deionized water between
measurements to avoid cross-contamination of the samples. Double
rinsing
is recommended when high accuracy is required.
2. To preserve electrode life keep the sponge in the protective cap
soaked with a pH 4 buffer. Cap TRACER when not in use. Store
vertically.
Do Not allow sensor to dry out.
3. Do not touch the electrodes. Touching the surface of the electrodes
may damage and reduce the life of the electrodes.
4. Salt deposits may build up in the storage cap and should periodically
be
rinsed away. These deposits could affect measurements at low
conductivity.

11
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.
NOTE: If the batteries are removed, stored data and user calibrations
will be cleared. A new user calibration will be required. Factory
calibrations will be retained.
All EU users are legally bound by the Battery Ordinance to
return all used batteries to community collection points or
wherever batteries/accumulators are sold.
Disposal in household trash or refuse is prohibited.
DISPOSAL: Follow the valid legal stipulations in respect of the disposal of the
device at the end of its life cycle
Other Battery Safety Reminders
¬Never dispose of batteries in a fire. Batteries may explode or leak.
¬Never mix battery types. Always install new batteries of the same type.
Cleaning and Conditioning the Electrode
Surface Cleaning – Only in case of visible surface contamination or if
readings should become erratic, use a disposable laboratory towel wetted
with ethanol or isopropyl alcohol and gently rub the surface, until no more
residue is visible.

12
Replacing the Electrode
The TRACER is shipped with an electrode attached. Electrode life is limited
and is dependant on the frequency of use and care. If the electrode needs to
be replaced, follow these steps for removing and connecting electrodes.
1. Turn meter off.
2. To remove the electrode, turn the collar counter-clockwise and
remove it.
3. Gently rock the electrode from side to side, pulling it downwards, until
it disconnects from the meter.
4. To attach an electrode, carefully plug the electrode into the meter
socket. Note that the electrode connector is keyed to ensure a proper
connection.
CAUTION: Take case to align pins carefully. Bent or broken ins will
cause the meter to malfunction.
5. Tighten the electrode collar firmly enough to make a good seal. A
rubber gasket will seal the electrode with the meter.
