Maintenance And Care - Farmex 1210 Manual De Usario

Maintenance and Care

1. The FARMEX™ 1210 is a precision-built, electronic instrument. Do not
subject it to prolonged periods of heat, cold or excessive mois-
ture. Never immerse the 1210 in water or leave it out in the rain.
2. Your 1210 must be kept clean. When cleaning is necessary,
wipe the tester with a slightly damp cloth. Make sure to clean the
electrodes in the test chamber. Bearing in mind that your 1210 is
designed to detect moisture, cleaning should be done at least 12
hours before use.
3. If the digital display reads below 75.0 (7.5 volts) when the
"TEST" button is depressed, the battery must be replaced.
(See Battery Installation).
Test Procedure – Silage
1. Prepare tester for use by LIGHTLY unwinding the pressure control knob
counter-clockwise as far as it will go. The indicator mark (a small dot
on the top of the knob) should be pointed towards the display panel.
IMPORTANT: DO NOT OVERWIND!
2. Remove a sample bag from storage compartment in tester and open
with a slicing action of your thumb and forefinger.
3. Select a representative sample of material to be tested (refer to Sam-
pling Procedure). Fill sample bag with as much material as possible,
gently compressing with your fingers.
4. Check that the bag seal is free from material. Pinch end of seal and
draw fingers across to close bag.
5. Make sure that the silage is uniformly packed and flattened in the
bag by gently patting and pressing between your hands. The pack
should be about 3/4" (20mm) thick.
6. Insert the sample pack into the test chamber and position it equal-
ly spaced between the two electrodes on the bottom of the test
chamber.
7. Apply pressure to the sample by turning the control knob clockwise,
carefully counting the number of turns. Continue turning and count-
ing until the yellow indicator band in the center of the knob appears
and its lower edge is level with the knob face. This indicates correct
pressure. Stop turning.
a) The number of turns applied should be within the range of 4 to
5-1/2, indicating that the amount of material under test is correct.
REJECT ALL TEST SAMPLES REQUIRING TURNS OUTSIDE
THIS RANGE, OR FALSE READINGS WILL RESULT.
