Connect the probe
to the external connector on the top of the meter.
Insert the probe into the bale
.
Press the read button (#1).
The meter displays the %MC for two seconds.
NOTES
The hay prod is electrically insulated, except at the metal points near the tip. The
moisture content measured represents the hay in contact with the tip of the prod
only.
Partially cured hay may have wide variations in moisture content throughout the
bale. Readings should be taken in several different parts of the bale and the
highest readings used as a guideline. The arrangement and compaction of hay
fibers in a bale may have an effect on meter readings.
If you are testing high density bales, we recommend using the H-3 handle with
the 830-2 10” prod, 830-3 18” prod, or the 830-4 36” prod. Using the handle/prod
combination eliminates excess stress on the instrument case that may occur
when trying to insert the prod into a high density or large bale.
When using the 36” prod, be sure to guide the prod into the bale with one hand
while pushing on the H-3 handle.
TESTING IN THE WINDROW
When testing in the windrow, push down on the pressure button until the palm of
your hand touches the screw that holds the button in place. The pressure button
depresses a calibrated spring inside the handle. When the screw touches the palm
of your hand, the pressure applied on the sample is 27 – 30 lbs., which closely
simulates the pressure in a standard bale of hay.
There are three ways to test moisture content in the windrow:
Test A:
Attach the #831
short pin prod to the H-3 handle and connect the handle to the
external connector on top of the meter.
Prepare a representative sample
by collecting hay from various parts of the
windrow.
Place hay in a non-conductive container
(such as a 5 to 10 gallon plastic pail)
and apply the short pin prod to the hay.
Press down on the electrode
until the head of the screw which holds the
pressure button, touches the palm of your hand.
