5. BATTERY
The meter works with a 9 volt 6F22 battery or
an alkaline battery of the same format. A battery
is included in the delivery.
Remove the battery if the meter is not used for
an long period of time. Insert a new battery prior
to each new season.
LOBAT
-sign at the upper left corner of the

Always first check the battery if you suspect any
problems with the operation of the meter.
Please note that the batteries discharge them-
selves slowly even if the meter is not used.
6. TECHNICAL DATA
Wile 27 can measure the moisture of baled hay,
straw, haylage and silage
The meter shows the water content of the
sample in percentage of weight. The definition
of moisture is based on measuring the loss of a
high frequency alternating current signal
(capacitance) in the sample.
The repeatability of the result is +/- 2,0 percent
of moisture or better.
Wile 27 meter is calibrated to give uniform
results with the official methods that are used
for defining the moisture content in hay and
straw.
The calibrations are defined with samples that
represent the most common available qualities
of hay and silage.
The straw scales are defined for the straw of
wheat and barley
