CHECK CALIBRATION
h Remove the prod from the top of the meter.
h Press the calibration check key
@
. Meter is in calibration
if the needle pointer moves to “20” on the scale. Any
reading within the green band on the dial is acceptable.
If you check the calibration and the display does not read
“20,” it is likely an indication of a low battery. If this
occurs, change the battery immediately. Continued use with a
low battery may cause the meter to go out of calibration. If
you have a fresh battery and the instrument still does not
indicate an acceptable calibration, return it to DELMHORST
for service. See
Service for Your Meter section.
TAKING A READING
Testing Baled Hay
h Connect the bale prod to the external connector on the top
of the meter.
h Insert the bale prod into the bale.
h Press the read key
!
and read the moisture content on
the scale.
Notes
hThe hay 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.
hPartially 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.
