BASIC OPERATION
Powering the TRACER
The Tracer uses four CR2032 Lithium Ion batteries. If the batteries are weak,
the BAT indicator will appear on the display. Press the ON/OFF key to turn
the TRACER on or off. The auto power off feature will shut the TRACER off
automatically after ten minutes of inactivity.
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 Compensation 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 TDS Conversion Ratio:
1. Turn the TRACER on.
2. Press and release the CAL button twice.
The stored ratio will appear in the display.
3. Press the MODE button to change the ratio
value in steps of 0.1.
4. When the desired ratio is displayed, press and release
the CAL 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.

Changing Temperature Units
To change the displayed temperature units between °F or °C:
1. With the TRACER off, press and hold the CAL button.
2. With the CAL button pressed, momentarily press the ON/OFF button.
When SELF CAL appears in the display, release the CAL button. The
TRACER will return to the operational mode with the temperature dis-
played in the new units.
Data Hold
Press the MODE button to freeze the current reading. The HOLD icon will
appear, the reading will be stored. Press the MODE key to return to normal
operation.
Auto Power Off
The auto-power off feature will automatically shut the meter off 10 minutes
after the last button was pressed. To disable the auto-off feature:
1. Press the ON/OFF button to turn the meter on.
2. Wait for the SELF display screen to appear. This is the second screen to
appear after turning on the meter. IMPORTANT: Review the instructions
for the next 3 steps before proceeding. Step 3 must be followed immedi-
ately by Step 4.
3. Press CAL button once quickly.
4. Press MODE and ON/OFF buttons simultaneously for approximately two
seconds. Quickly release buttons.
5. oFF will be displayed on the screen. Watch carefully. It will disappear
quickly.
6. The auto power off feature will be restored automatically when the meter
is turned off. Auto-off is the default function when the meter is turned on.
Low Battery Indicator
The “BAT” indicator will be displayed when the batteries become weak. Refer
to the maintenance section for battery replacement information

TESTING
Getting Started
1. Remove the cap from the bottom of the TRACER to expose the electrode.
2. Before the first use, rinse the electrode in deionized water and dry.
3. For best results, calibrate for conductivity with a standard in the expected
range of the sample. For maximum accuracy calibrate from low conductivity
value standards to high conductivity value standards.
4. Store 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 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 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 diagnos-
tics).
4. Press and hold the MODE button to scroll to the
desired measurement mode.
5. Insert the electrode into the sample making sure
that the electrodes are completely submerged.
6. Slowly stir the sample with the TRACER to
remove air bubbles.
7. The meter will autorange to the proper range and the
reading will be displayed.
8. Rinse the electrode in distilled water. Replace the cap.
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.
Storing Readings
1. After the reading is displayed press and hold the
MODE button to store the current reading. The
meter will enter the HOLD mode and HOLD will
be displayed. The storage location number will
be displayed on the lower display followed by the
reading being stored.
2. Press the MODE 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 button.
1. Press the CAL button and then press the MODE 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.
