Operation
BEFORE TAKING THE FIRST TEST
STEP 1 Take a 9-volt battery and place it in the battery compartment on the bottom of your
tester.
• Be sure to pay attention to the polarity markings on the tester and match them to the
battery when placing it in the tester.
STEP 2 Your 5-gallon bucket must be marked before using it with your windrow tester.
• Before marking your bucket, check that it is clean and dry on the inside.
• Using a tape measure or ruler, measure 10 inches up from the bottom of the bucket
and mark it in several places with black electrical tape or a black permanent marker.
See Figure A.
• Once the bucket is marked, a more permanent mark can be made in the bucket by
simply drilling holes in the bucket at the 10-inch mark.
• Marking your bucket at 10 inches up from the bottom ensures that during the testing
process your windrow tester sensor tip will not get closer than 3 inches from the bot-
tom of the bucket. Allowing the sensor tip to come within 3 inches of the bottom may
alter the moisture measurement.
STEP 3 Connect the sensor to the tester body. Take the sensor’s threaded end and
connect it to the tester body by threading and tightening it in a clockwise direction.
See Figure B. Be sure the sensor is tight, but it does not need to be more than
hand-tightened.
