Measurement Procedure - LaMotte Tracer 1766 Manual

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
