Instructions for Completing Form FGIS-923, “UGMA Moisture Meter Test”

Indentification Block.

1. Fill in Field Office or Agency information.

2. Check the appropriate boxes for the status of check testing the meter.

Part A.

1. Verify current official calibration version. Update all obsolete calibrations. Initial to indicate that all calibrations are correct.

For current calibration versions refer FGIS Directive 9180.61.

2. Enter meter model and serial number along with scale model and serial number.

3. Enter meter serial number.

4. Enter SCD1 and SCD2 values.

Part B.

1. Enter the result of the first drop (meter value). Record the result to the nearest 0.1.

th

2. Enter the weight reading from the lab scale. Record to result to the nearest 0.1.

3. Enter the difference (meter minus scale weights), if not calculated automatically.

4. Repeat Item 1 through Item 4 for a total of five drops.

5. Enter the average difference (average of five differences of meter minus scale weights), if not calculated automatically.

6. Enter the range of differences (total spread of the differences of meter minus scale weights), if not calculated automatically.

Part C.

1. Enter the TRN (sample ID) listed on the sample bag.

2. Enter the weight recorded on the sample bag to the nearest 0.1.

3. Remove the wheat sample bag from the outer polyethylene bag and weigh the sample bag on the scale to the nearest 0.1.

4. Enter the weight reading from the lab scale to the nearest 0.1.

5. Enter the difference (bag minus scale weight) if not calculated automatically.

6. Enter the values for information displayed from the first drop on the meter. Moisture, Test Weight, Sample Temperature.

7. Repeat step 6 for a total of six drops.

8. Enter the average (average of 5 drops), if not calculated automatically.

9. Enter the deviation ( average moisture from 5 drops minus Standard avg moisture), if not calculated automatically.

10. Enter name of the field test meter operator.

11. Enter the date.

12. Check the box, if the meter is approved for use, or start the retest or repairing process.

13. Any additional comments necessary concerning the test or information about the meter.
