Testing Baled Cotton
h Attach the # 30-E/C Electrode to the connector on top of
the meter.
h Slide the plastic spacer over the # 491 contact pins from
the bottom of the pins, mount the pins in the chucks and
tighten the set screws. (The
# 491 contact pins are not
inserted into the chucks for shipping purposes).
h Set the Scale to #1 Lint cotton and select a set point.
h Insert the electrode pins into the bale and press the read
key
!
.
h Place the pin spacers near the tips of the pins when con-
tact is first made with the bale. This helps to keep the pins
parallel as they are forced into the bale.
The # 491 contact pins are insulated, except for 1-3/4” at
the tip. The insulation helps to identify the area of moisture,
since the reading is obtained from the tip of the pin. Keeping
track of moisture readings as the pins are pushed into the
bale will give an idea of the uniformity of moisture distribu-
tion in the bale. Higher moisture readings near the surface
are an indication that the cotton has been exposed to higher
moisture after baling.
The C-2000 gives accurate results on normally compressed
bales. If the bale is loosely packed, the meter will read lower
than the actual moisture content. If the bale is very tightly
packed, the readings will be only slightly higher than normal,
and as a rule, no correction needs to be made.
Well-conditioned material will give uniform readings; however,
material that is baled before it is dry will show a wide range
of moisture content. Several tests should be made on each
bale, and you should note the average and the highest read-
ings of these tests.
Testing Yarn
h Connect the # 37-E/C multi-pin electrode to the connector
on top of the meter.
h Set the scale to # 1 Lint cotton and select a set point.
h Insert the electrode pins into the yarn and press the read
key
