LaMotte Tracer Salt Meter - Manual (Page 11)

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/HOLD button
to scroll to the desired measurement
mode.
4. Immerse the TRACER electrode in the sample.
Make sure the electrode is completly 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
autoranging.
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
