WEIGHT TEST — CHECKING TEST WEIGHT FOR ACCURACY
Weight Test — Allows user to check the calibration of the test weight function
of the tester. By following the steps indicated, the fi nal reading will let the user
know if the test weight is off. Test weight reading errors could indicate that grain or
debris is stuck under the top ring or load cell is damaged. See page 18, Cleaning
the Tester, if weight test readings are not within tolerance.
1. Turn on Unit (press ON/OFF button)
2. Use UP/DOWN buttons to scroll to "SETTINGS" then press ENTER
3. Use UP/OWN buttons to scroll to "Weight test" (Figure 7) then press ENTER
4. Place test weight or 10 new quarters into the test cell when the screen
indicates to "PLACE WEIGHT." Once the weight or quarters are placed
in unit, wait for reading to display. The asterisk in the upper right hand corner
indicates the tester is steady and the weight is then accurate (Figure 8).
NOTE: Tolerance is +/- 0.1 for the number of quarters — 9.9 or 10.1 is within
tolerance for 10 quarters. Please use 10 new quarters for your check if there is
not a test weight available.
