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.
TDS Compensation 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 range is 0.4 to 0.6 auto. 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
(ppm or mg/L):
1. Turn the TRACER on.
2. Press and release the CAL button twice.
The stored ratio will appear in the display.
3. Press the MODE button to change the
ratio value in steps of 0.1.
4. When the desired ratio is displayed, press
and release the CAL 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.
