OPERATING PROCEDURE – PREHEATING
IMPORTANT:
If the temperature of the grain sample is 20˚F (11˚C) more or less than
the temperature of the unit, preheat the tester and test as follows:
PREHEATING PROCEDURE
1. Remove cap (A) and inspect test cell (B) to be sure that it is clean and empty.
2. Press ON-OFF button (C) to turn on tester. The display (D) will show ALWAYS
AVERAGE 3 TESTS for approximately 7 seconds, then will show ALFALFA (initial
operation) or the name of the last grain tested.
3. When the grain to be tested has been selected using the SELECT arrows (E), fill
the test cell (B) even to the top of the cell with sample to be tested.
4. Replace cap loosely. DO NOT TIGHTEN.
5. After 30 seconds, empty test cell and immediately refill with fresh grain.
6. Replace cap (A) and tighten until pressure-indicator screw (F) is flush with the
top of cap (A). (Use finger-flush test as illustrated in Figure 1.)
7. Immediately press TEST button (G). The words TESTING will be displayed for
about 10 seconds, while the tester compensates for temperature. The moisture
% and temperature will then be displayed for about 10 seconds.
