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.
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 range is 0.4 to 0.6 auto. 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
(ppm or mg/L):
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 the Displayed Temperature Units
To change the displayed temperature units between °C or °F:
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
displayed 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 automatically shuts the meter off 10 minutes
after the most recent button press:
Auto Power OFF Disable
1. To disable the Auto Power Off feature:
2. Turn the unit on.
3. Press CAL once (quickly).
4. Immediately and simultaneously press the MODE and ON/OFF
buttons for approximately 2 seconds, until "oFF" is briefly displayed.
To disengage this feature, turn the unit off with the ON/OFF button. The next
time the unit is powered up, Auto Power OFF mode will be engaged again.
Low Battery Indicator
The “BAT” indicator will be displayed when the batteries become weak. Refer
to the Maintenance section for battery replacement information.

Measurement and Display Considerations
¬If the unit appears to be locked (display frozen). It is possible that
the Data Hold mode has been inadvertently accessed by pressing
the MODE button. (“HOLD” will be displayed in the bottom left of the
display.) Press the MODE button again or turn the meter off and then
on.
¬For maximum accuracy, 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.
Considerations and Technique
¬Do not touch the inner surfaces of the conductivity electrodes.
Touching the surface of the platinized electodes may damage and
reduce the life of the probe.
¬Store the electrode in the wetting cap with the sponge moistened with
pH 4.0 buffer solution.
¬Always rinse the electrode in deionized or distilled water between
measurements to avoid cross contamination of the sample. Double
rinsing is recommended when high accuracy is required.
¬Periodically, accumulated salt deposits from the reference electrode
may build up in the storage cap, and should be rinsed away. These
deposits could affect measured values of low conductivity samples.
¬When measuring low conductivity samples, extra care is recommended
in rinsing the probe to avoid contamination of the sample with electrolyte
from the pH reference electrode. This will only be a factor when
the volume of the sample. (Example: Try a 200 to 500 mL sample.)
¬When a 20mL sample cup is usedthe electrode should not be allowed
to sit in the sample for any longer than necessary, to avoid electrolyte
leakage into the sample, raising the conductivity value.

TESTING
Getting Started
¬Remove the cap from the bottom of the Tracer to expose the pH
electrode, reference junction and conductivity electrodes.
¬Before the first use or after storage, soak the electrode in tap water or
pH 4 buffer solution for about 10 minutes.
¬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 moves to
the very tip of the electrode. The electrolyte should fill the circular
junction window at the tip of the electrode.
¬White KCL crystals may be present in the cap or on the electrode.
This is to be expected depending on the length of time in storage.
These crystals will dissolve while soaking the electrode or they can
be rinsed away with tap water.
¬For best results calibrate with pH 7 buffer solution first, then calibrate
with the buffer solution closest to the expected pH value of the solution
or material to be tested.
¬To preserve the pH electrode life keep the sponge in the protective cap
soaked with tap water or pH 4 buffer solution.
¬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 value standards.
¬When the meter is calibrated for conductivity, salinity or TDS the meter
must be in the conductivity mode. See page 14. For storage see page
17.
Changing Measurement Function
The meter can be set to measure pH, Conductivity, TDS, or Salinity. To
change the mode:
1. Press and hold the MODE button for 2 seconds and the display will
begin to scroll through the units.
µs (Conductivity: pH; ppm S (Salinity); ppm (TDS); mg/L (TDS
NOTE:The "HOLD" finction cannot be on when changing the
measurement function. If "HOLD" is displayed in the lower left corner
of the display, briefly press the MODE button to turn it off.
10
2. When the desired units are displayed, release the MODE button.
NOTE: 1 part per thousand (ppt) equals 1000 parts per million (ppm).
Example: 3.1 ppt = 3,100 ppm.
3. Release the MODE key when the desired mode is displayed.
NOTE: The “HOLD” function cannot be used when changing the
measurement function. If “HOLD” is displayed in the lower left corner
of the display, briefly press the MODE button to turn it off.
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, like pools, go
to step 2
2. Press the ON/OFF button. (8888 and then SELF
CAL will appear in the display during the initial
diagnostics).
3. Press and hold the MODE button to scroll to the desired
measurement mode.
4. Immerse the TRACER electrode in the sample.
Make sure the electrode is completely 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 auto-
ranging.
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
