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.
Electrode Recognition
When the TRACER is turned on, it will recognize the type of electrode
that is connected and will display the appropriate unit of measure.
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 fi xed at 0.5. The stored ratio
factor will briefl y appear in the lower temperature display when the
meter is fi rst 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.
