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.
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.
