Page 7: Basic Operation
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 ...

Changing the displayed temperature units to change the displayed temperature units between °f or °c: 1. With the tracer off, press and hold the cal/recall button. 2. With the cal/recall button pressed, momentarily press the on/off button. When self cal appears in the display, release the cal/recall ...
Page 9: Testing
Testing getting started 1. Remove the cap from the bottom of the tracer to expose the electrode. 2. Before the first use, rinse the electrode in deionized water and dry. 3. For best results, calibrate for conductivity with a standard in the expected range of the sample. For maximum accuracy calibrat...

Measurement 1. 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. 2. Immerse the tracer electrode in the sample. Make sure the electrode is completely submersed. 3. Press the on/off button. (8888 and then self cal will appear in the di...

7. Press the on/off button to turn the tracer on. Make sure the meter is in the tds mode. 8. Immerse the electrode in the filtrate. Make sure the tip of the electrode is completely immersed. 9. Stir the filtrate with the electrode to create a homogeneous solution. 10. Gently stir the filtrate with t...
Page 12: Calibration
Clearing the stored memory turn the tracer on. Press and hold the on/off button for 4 second the display will briefly desplay “clr” when the memory is cleared. Calibration for the most accurate results, allow sufficient time for the temperature of the probe to reach the temperature of the sample bef...

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. The calibrations for the other two ranges will be saved even though the indicators for those ranges are no longer display...

Page 16: Maintenance
Maintenance storage 1. Rinse the electrode in distilled or deionized water. 2. Store the electrode dry with the cap on. 3. Always rinse the electrode in deionized water between measurements to avoid cross contamination. Double rinsing is recommended when high accuracy is required. Battery replacemen...
Page 17: Contaminant
Electrode cleaning recommendations do not soak the electrode in the solutions for longer than the recommended length of time. To do so may cause a reference potential shift which will cause a degradation in performance or failure. When cleaning the probe, do not scratch or damage the platinized elec...
