Electrode Sensor Description
The sensing electrode is a europium doped lanthanum fl uoride single crystal that
has been incorporated into a removable sensing module that houses a reference
electrode and temperature measurement system. The high resistance electrode
signals are impedance converted to a low resistance output in the sensing module
to ensure stable and noise free performance.
TISAB TesTabs Tablet Description
The Fluoride TRACER allows the users to follow the ASTM and EPA standard
methodology using any of the TISAB reagents and standards already in use.
TISAB TesTabs contain all of the essential and approved chemicals that are
found in the usual TISAB reagents. The “dry” reagent does not contribute to
sample dilution.

Powering the Fluoride TRACER
The Fluoride TRACER uses four (4) CR2032 lithium ion batteries. Press the ON/
OFF key to turn the meter on or off. If the batteries are weak, the ‘BAT’ indicator
appears on the LCD. The auto power off feature shuts the meter off automatically
after approximately 12 minutes of inactivity. The auto power off feature may be
temporarily disabled for convenience or for extended polarization time.
Power-On Diagnostics
1. When the meter is switched ON the LCD displays ‘SELF’ and ‘CAL’
while the meter runs a diagnostic routine.
2. During this time the meter is recalling the user calibration data, performing self diagnostics & initializing the circuitry.
3. When completed, the meter proceeds to the normal measurement mode.
Calibration
The Fluoride TRACER can be calibrated between 1.0 ppm and 10.0 ppm or
between 0.5 and 5.0 ppm Fluoride ion. The following calibration procedure
assumes the normal 1.0 to 10 ppm range has been chosen.
1. Fill a sample cup to 20 mL with a 1 ppm fl uoride standard Add one
TISAB TesTab (7024). Crush tablet with Tablet Crusher (0175) and mix
until the tablet disintegrates. Or prepare a traditional 1.0 ppm fl uoride
standard and TISAB reagent, or use pre made mixed TISAB and 1.0 ppm
standard. Pour 20 mLs of this standard solution into the sample cup.
2. Rinse the end of the Fluoride TRACER module in TISAB solution and
wipe thoroughly with paper tissue.
3. Place the Fluoride TRACER in the 1.0 ppm standard/TISAB solution and
switch the instrument ON using the ON/OFF key. The instrument will
now run its self-calibration.
4. The instrument will enter the HOLD mode when stabilized in the 1.0 ppm
solution.
5. Press the CAL key; ‘CAL’ will appear in the display followed by 0.5ppm
and 5.0 ppm. Continue holding until 1.0 ppm is shown. Release the CAL
key. After the display stops blinking the instrument will enter the HOLD
mode.
6. For a 2 point calibration, repeat the calibration procedure with a 10.0 ppm
standard.
7. The instrument is now calibrated and ready for use. The circled ‘L’ and
‘H’ icons on the display indicate that the low range (L) and high range
(H) calibrations have been completed.

Page 10
Calibration Frequency
A 1 point calibration is adequate prior to each new measurement batch or if more
than 24 hours has elapsed since the last calibration. A 2 point calibration should
be performed if the meter is new or has not been calibrated for 5 days.
Slope Adjustment
1. Slope adjustment, although not a frequent requirement, can be carried
out by following the instructions in Calibration above and by calibrating
with a 10.0 ppm standard after calibrating with the 1.0 ppm standard.
2. Press the CAL key until 10.0 ppm appears. Slope adjustment is then
complete.
Other standards
As mentioned the Fluoride TRACER can also be calibrated between 0.5 and 5.0
ppm Fluoride. Follow the calibration instructions above but substitute 0.5 ppm
for 1.0 ppm and 5.0 ppm for 10.0 ppm.
Measurements
1. Prepare an unknown solution by adding, crushing, and dissolving one TISAB TesTab (7024) in 20 mL of the sample or by adding TISAB reagent
to the sample in the same dilution ratio as for the calibration procedure.
Mix thoroughly.
2. Rinse the end of the Fluoride TRACER.
3. Place the Fluoride TRACER into the prepared unknown sample. If the
instrument is in the HOLD mode, press MODE/HOLD to unlock HOLD.
4. After 25 seconds, the instrument will display the value of the unknown
concentration and will then enter the HOLD mode.
Note: The readings can be stored in the memory by pressing the MODE/
HOLD key for approximately 3 seconds as explained in a subsequent section of this user guide.

Maintenance
Battery Replacement
1. Twist off the battery compartment cover.
2. Holding the battery housing in place with a fi nger, pull out the battery
carrier using the two small tabs.
3. Replace the four (4) CR2032 batteries observing proper polarity.
4. Replace the battery carrier, reattach the battery compartment cap and
tighten securely.
Electrode Replacement
1. To remove the electrode, fi rst turn the instrument OFF and then unscrew
and remove the electrode retaining collar. (Turn the collar counter-clockwise to remove).
2. Gently rock the electrode from side to side, pulling it away from the
meter until it disconnects.
3. To attach an electrode, align the positioning “keys” on the electrode and
the main body housing and then carefully push the electrode into the
meter socket until it is fully seated. CAUTION: Take care to align pins
carefully. Bent or broken pins will cause the meter to malfunction.
4. Tighten the electrode retaining collar fi rmly enough to seal the electrode
with the meter.
Electrode Storage
1. The module and can be stored wet or dry. If stored dry it will be necessary to allow approximately 15 minutes of soaking in a fl uoride solution
before the specifi ed performance can be achieved. It is recommended that
the electrode be stored wet in the last test solution used by the instrument
(fl uoride ion plus TISAB reagent).
2. The instrument will give an error code when the electrode can no longer
be calibrated.
3. If the instrument will not calibrate, clean the fl uoride electrode surface
and recalibrate the instrument. If the meter still does not calibrate, replace
the electrode.
