BASIC OPERATION Powering the TRACER The Tracer uses four CR2032 Lithium Ion batteries. If the batteries are weak, 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 ten minutes of inactivity.
Changing Temperature Units To change the displayed temperature units between °F or °C: With the TRACER off, press and hold the CAL button. With the CAL button pressed, momentarily press the ON/OFF button. SELF CAL When appears in the display, release the CAL button. The TRACER will return to the operational mode with the temperature dis- played in the new units.
TESTING Getting Started Remove the cap from the bottom of the TRACER to expose the electrode. Before the fi rst use, rinse the electrode in deionized water and dry. For best results, calibrate for conductivity with a standard in the expected range of the sample.
Measurement 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. Immerse the TRACER electrode in the sample. Make sure the electrode is completely submersed. Press the ON/OFF button. (8888 and then SELF CAL will appear in the display during the initial diagnos- tics).
Filter the contents of the fl ask. Collect the fi ltrate in a beaker. Rinse the electrode with distilled or deionized water to remove impurities. Press the ON/OFF button to turn the TRACER on. Make sure the meter is in the TDS mode. Immerse the electrode in the fi...
The last stored reading taken will be displayed fi rst. To advance to the previously stored readings, press the MODE button. The location number is displayed fi rst, followed by the reading stored in that location. To exit the storage mode, press the CAL button and the TRACER will return to normal operation after displaying “End”.

The calibration range indicator will appear on the display for each range that is calibrated during a power on cycle. Low Range, 84 μS/cm Medium Range, 1413 μS/cm or 3,000 ppm SaH High Range, 12.88 mS/cm (12,880 μS/cm) NOTE: Each time the calibration mode is entered all calibration range indicators will be cleared, but only the calibration data for the currently selected range will be replaced.

Function/ Resulting Action Power Mode Key Press Sequence Enter CON/TDS Press and release the Ratio (ppm or CAL button twice in mg/L) quick succession. Change CON/TDS Momentary press of Ratio (ppm or MODE button. Each mg/L) press increases ratio by 0.1 from 0.4 to 1.0.
MAINTENANCE Storage Rinse the electrode in distilled or deionized water. Store the electrode dry with the cap on. Always rinse the electrode in deionized water between measurements to avoid cross contamination. Double rinsing is recommended when high accuracy is required. Battery Replacement Twist off the battery compartment cap.
Replacing the electrode Unscrew and remove the electrode collar. Turn collar counter-clockwise. Gently rock the electrode side to side, while pulling it away from the meter, until it disconnects from the electrode socket. To attach an electrode, align the slots and carefully plug the electrode into the meter socket.
