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.
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.
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.

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/RECALL button.
2. With the CAL/RECALL button pressed, momentarily press the ON/
OFF button. When SELF CAL appears in the display, release the
CAL/RECALL button. The TRACER will return to the operational
mode with the temperature displayed in the new units.
Data Hold
Press the MODE/HOLD button to freeze the current reading. The HOLD
icon will appear. The reading will be stored. Press the MODE/HOLD 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 immediately by Step 4.
3. Press CAL/RECALL button once.
4. Press MODE/HOLD and ON/OFF buttons simultaneously, for
approximately 2 seconds.
5. oFF will be displayed on the screen. Watch carefully. It will
disappear quickly.
6. To re-enable the auto-off feature, repeat steps 3 and 4. ON will be
briefly displayed on the screen.
7. 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 pH
electrode, reference junction and the conductivity electrodes.
2. Before the first use or after storage, soak the electrode (with cap
removed) in tap water or pH 4 buffer 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 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.
5. Calibrate with pH 7 buffer prior to the first use or after prolonged
storage.
6. When the meter is calibrated for conductivity, salinity or TDS the
meter must be in the conductivity mode. See page 15. For storage
see page 19.
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)
pH
ppm S or ppt S (Salinity)
ppm or ppt (TDS)
mg/L (TDS)
NOTE:1 part per thousand (ppt) equals 1000 parts per million
(ppm). Example: 3.1 ppt = 3,100 ppm
3. Release the MODE/HOLD 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/HOLD button to turn it off.
