“Best Practices” for Moisture Tracker

General Use and Care

Keep the glass lens clean and free of debris or moisture. Clean with monofilament cloth and solution designed for

use with eyeglasses or LED type screens. Do not use any cleaning solution that may leave a residue which could

interfere with readings. Any dust, debris, etc., WILL effect calibration and results!

Clean the screen/grate on the end of the probe between samples or during scans as needed. A stiff bristle brush

works well for this.

Check regularly for potential updates to software or feed calibrations.

Calibration

Check calibration daily, or more often if doing continuous-type testing, such as during forage harvest. Best if re-

calibrated any time the result is < 99.50%

Keep Calibration disk/probe stable during calibration or checking calibration. Place the calibration disk on a table or

other stable, flat surface. Hold probe firmly against the disk during the procedure; avoid movement of the probe.

Keep calibration target disk CLEAN and DRY. Always be sure to clean the Moisture Tracker screen/grate prior to

placing it against the calibration target disk to avoid contamination. Always replace the cover on the calibration

target disk and store it in the carrying case. Do not leave it exposed to direct sunlight.

If the unit is stored in a place that differs more than a few degrees from the place where it will be used, allow the

unit to acclimate to the ambient temperature of the test area. Turn on the MT for 10 minutes or more where it will

be used prior to calibrating or taking a measurement. Change the power-down settings if needed.

Measurements

Hold the probe squarely on the material being sampled, eliminating external light error, but not to the point where

material pushes up through the screen. This is extremely critical when testing finely ground materials. The weight of

the unit on the sample material is generally enough.

Do not move lift or move the unit until you hear the audible beep confirming the scan has completed. An

inadvertent trigger pull or premature move that results in the unit beeping while in the air can be eliminated from

the sample by pressing the back arrow button.

If sampling multiple materials, it is advised to start with the driest material first and end with the wettest or stickiest

material last. This will minimize the need to do a major cleaning between materials.

In extreme cold environments near or below freezing, bring a sample to a more moderate environment to perform

the testing. Frozen material WILL NOT give accurate results. Completely thaw frozen material prior to sampling.

Increase the minimum number of scans from 20 up to 30 (or more) to increase accuracy for materials of these types:

fresh/green chop, material with a coarse chop length, material with lower moisture, material that is a mixture of

grass and legumes.

Take readings on a freshly exposed layer of the material. Get beneath the surface that may have already dried out.

Variations in moisture can quickly change on surface material exposed to sunlight and air. Piles of material that get

rained on should be mixed thoroughly prior to sampling to get a more representative reading.

Moisture Tracker Adjustment Procedure

The Dry Matter results (DM) of a MT (MT) can be aligned with a known reference DM (from Lab, Dehydrator,

Koster, etc.). Individual feedstuff DM readings may not all align the same due to natural variations in feeds,

but should be within acceptable ranges (+/- 2%). If you have questions please contact:

1. Gather samples of 2 –3 common feedstuffs (corn silage, alfalfa haylage, high moisture

ground shell corn, etc.) that have Calibrations available for the MT. Gather enough material

that you can send some to the lab and save back enough to do future scans with the MT.

2. Divide the total sample of each feedstuff into one portion for testing per your preferred

reference method, a second portion for original measurement with MT, and a third portion

(packaged in an air-tight container (zip-lock bag) and stored in a refrigerator or freezer) for

later MT readings to verify the results after adjustment.

3. Take 2-3 DM readings on each of the feedstuffs using the MT.

4. Compare DM readings with reference DM reading. Compare the reference DM results to

your original MT DM readings.

If the MT DM is within 1-2% of the reference DM: do nothing.

If the MT DM is more than 2% higher than the reference DM: decrease the Calibration

Code.

If the MT DM is more than 2% lower than the reference DM: increase the Calibration

Code.

5. Adjust the Calibration Code:

On the MT, Select Main Menu > Calibrate Sensor > Enter New Calibration Code (3)

Change the Calibration Code by 5. (Ex: changing a code of 545493 to 545488 –a

reduction of 5 counts.) Use the right or left arrow buttons to get to the desired digit

and the up or down arrows to scroll the digit to the desired number. Press the “Enter”

button to save the adjusted code.

6. Recalibrate the MT.Hold the probe on the Calibration Disk and press “2”.

7. Take 2-3 new DM readings on each of the stored feedstuff samples using the MT. Be sure

that the samples are completely thawed out if they had been frozen. If you decreased the

code number, you should see a reduced DM reading for each of the feeds.

8. Compare with reference DM reading.

If the MT DM is within 1-2% of the reference DM, no more adjustment is needed.

If the MT DM is still more than 2% higher or more than 2% lower than the reference

DM, make additional adjustments to the calibration code as in step 5.

9. Record the adjusted Calibration Code. Write down the adjusted 6 digit calibration code and

save it with the disk. Use the adjusted code for future calibrations.
