5. START-UP AND OPERATION
d. Why take several samples? The electronics average the grain moisture and therefore
it is possible to have a sample that is either wetter or dryer than the meter is reading (if
the meter is changing rapidly while sampling).
e. Take samples at the discharge, not from the storage bin, when monitoring a drying
operation. If you do not have a sampler at the discharge, contact your dealer and have
one installed. See the following
(Calcu-U-Dri Moisture/Matic Sampling Chart).
Calc-U-Dri Moisture/Matic Sampling
The Chart shows grain moisture readings (from a real situation) as they should be taken to
obtain a realistic moisture value.
Question : Where would you set the moisture offset, +0.3 or +0.6?
Answer : Most would want to set it to +0.3 which would make it match the point of
sale’s moisture reading.
5. The moisture Set Point is adjusted by turning the Set Point adjustment knob while holding
the “Display Set Point” paddle switch down. Turning the knob clockwise will increase the
moisture Set Point and counterclockwise will decrease the moisture Set Point (0 to 25).
Note: The Set Point will change whenever the knob is moved.
6. Adjust the main speed adjustment knob to the desired discharge rate. This is the typical
metering roll speed required to obtain the desired discharge moisture.
7. Switch the mode switch to “Automatic” and the Moisture/Matic will start to control the speed
of the dryer metering rolls. The dryer will operate at “Low” speed when the moisture content
displayed on the meter is wetter than 0.3 percent or more than the moisture Set Point. It
will operate at “Main” speed when the moisture displayed is within +0.3 percent or -0.3
percent of the moisture Set Point, and will run at “High” speed when the moisture is 0.3
percent or more below the moisture Set Point.
