TO RESET THE METER
Press and release the calibration check button (#2).
Within one second, press and hold the scale button (#3).
The meter will reset itself and display “119.” This indicates that the meter has been
reset to scale #1 (hay) and default set-point 19%. It will also clear all of the readings
stored in memory.
TAKING A READING
TESTING BALED HAY
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 bale 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-4 handle with the
830-2 25cm prod, 830-3 45cm prod, or the 830-4 90cm 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 90cm prod, be sure to guide the prod into the bale with one hand while
pushing on the H-4 handle.
TESTING IN THE WINDROW
There are three ways to test moisture content in the windrow:
Test A:
Attach the #831 short pin prod to the H-4 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 the read button (#1) and take a reading.
Mix the sample once again and take at least two more readings. Use the highest
readings.
