QUICK START
The following procedure describes a quick-start for the Fluoride TRACER using
the TISAB TesTabs. Detailed operating instructions can be found on the pages
that follow.
Preparation
1.
Remove the Fluoride TRACER, tablets, electrode module and sample cup
from the box. Remove caps from module.
2. Fit the electrode module onto the end of the meter body, making sure that
the slots line up correctly, and tightly turn the module retaining ring to
secure the assembly.
3. Wipe the fl uoride crystal and reference junction with a damp tissue.
Calibration
1.
Fill a sample cup to 20 mL with a 1.0 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 premade 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 mixture.
4. Switch the instrument on using the ON/OFF key. The instrument will
now go through its internal calibration.
5. The 1.0 ppm reading will stabilize in approximately 35 seconds and the
instrument will enter HOLD mode.
6. When in HOLD mode press the CAL key and hold until 1.0 ppm and
‘CAL’ appear in the display. Release the CAL key.
7. Wait until the display stops blinking; the instrument will enter the HOLD
mode.
8. The instrument is now calibrated and ready for use or calibration with a
second standard.
