Occasional higher readings may occur if, in addition to the
effect of the increased conductivity due to the stabilizer, the
bales tested also show an increase in temperature and
“sweating.” As the stabilizer becomes more thoroughly
absorbed and the sweating subsides, the meter readings
recede to the initial level and will continue to decrease,
assuming that the bale becomes progressively dryer.

Sample Size

When testing baled hay, it is essential to take readings at
several different points in the bale. Hay moisture may vary a
great deal in the same bale. For example, at one point bale
moisture may be 20% and at another over 35%.

More tests must be made whenever the variations among
readings are greater. If there is a possibility of high moisture
areas, samples from these locations should be taken. Areas of
high moisture content will spoil, resulting in loss.

It is extremely important to note the high readings and the
frequency at which they occur.

USING THE METER FOR
CONTINUOUS MONITORING

The FX-2000 can be used for
on-the-go-monitoring, pow-
ered by the 12v tractor bat-
tery.To install the meter and
power supply:

h

Attach the red lead of the power cable to a positive (+)

12-volt supply point controlled by the ignition switch or
attach it directly to the tractor battery.

h

Ground the other lead. A replaceable fuse protects the circuit.

The meter can also be powered independently of the trac-
tor’s electrical system by using a 12V, (Eveready 732 or
equivalent) all-purpose battery.

h

Select a location in the cab where the display can be easily

viewed while baling. Install the stainless steel mounting
loop and slide the meter onto the loop.

h

Connect the power cable to the meter.
