LaMotte Tracer SAL Meter - Manual (Page 6)

BASIC OPERATION
Powering the TRACER
The Tracer uses four CR2032 Lithium Ion batteries. If the batteries are
weak, the BAT indicator will appear on the display. Press the ON/OFF
key 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 TDS Conversion Ratio:
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.
