Monitor and average grain moisture continuously as you harvest.
No more stopping or waiting to check grain moisture. The DMC Combine Calc-U-Dri tells you the moisture of the grain as you are combining. No longer do you have to stop the combine, climb up to the hopper, grab a handful of grain and put it through the tester to check the moisture. Calc-U-Dri monitors the actual moisture of all the grain as it goes from field to hopper. Knowing the moisture of your grain can be an important factor in maximizing your profits at harvest time.

Harvesting grain which is too wet can...
• Slow down the drying process.
• Increase drying costs.
• Increase grain damage when harvesting (increase FM), which will slow the drying and increase FM dockage.
• Reduce your bottom-line dollar.

The Combine Calc-U-Dri can prevent all of this and save you money.

Calc-U-Dri uses proven technology for accurate moisture readings
Combine Calc-U-Dri's electronic design is well-proven. Used in grain drying, the Calc-U-Dri has been in use since 1986 on thousands of farms, helping farmers make sure they do not overdry grain needlessly, thus saving money.

Now this same technology is available to provide combine operators with instant moisture readings during harvest.

Introducing Combine Calc-U-Dri II with short & long term grain moisture averaging
The Combine Calc-U-Dri II is the newest Combine Calc-U-Dri. This model provides instant & constant grain moisture readings as the standard model does.

Combine Calc-U-Dri II also gives short and long term moisture averages.

Example: The short average can be used for a hopper of grain or just one round in the field. The long average can show the moisture in a truck load or one or more fields of grain.

Simple to use
DMC designed both Combine Calc-U-Dri products for ease-of-use.
• All switches and knobs are easy to work even when you have gloves on.
• The liquid crystal display (LCD) is easy to read even in bright sunlight. It also is back lit for easy readability at night.
• A high moisture indicator can alert you to grain being harvested which is higher in moisture than you desired. A red light will always turn on when grain moisture is above the moisture limit setting. The operator has the option of hearing an audible alarm when high moisture grain is sensed.

Averaging switch improves accuracy
An averaging switch, located in the clean grain auger, automatically tells the Combine Calc-U-Dri II when there is grain present to use for the average. An example is when the combine is turning on the end of a row and no grain is present to obtain a moisture reading. This lack of a moisture reading would automatically be eliminated from the average, thus making it a a true average of what is being harvested.

Component definitions
The following descriptions are of the Combine Calc-U-Dri II (as shown above).
• On/Off Switch: Flip the switch down, and the unit is on with an audible alarm. This alarm sounds for one-half second whenever grain moisture reaches the moisture limit the operator has set. Flop the switch up, and the unit is on without the audible alarm.
• Limit Adjustment: This knob is turned, while holding down the Moisture Limit Display Switch, to adjust for the grain moisture the operator would like to be alerted to by the audio and/or visual alarm.
• Temperature/Moisture Limit Display Switch: Push the switch up to read the grain temperature on the liquid crystal display. Pull the switch down when adjusting the moisture limit or displaying the moisture limit.
• Long Average Display Switch: Pull this switch down to see the long term average moisture displayed on the liquid crystal display. Push the switch up and hold until the beeps stop (four audible beeps will sound) to reset this average. Resetting the long average does not disturb the short average.
• Moisture Offset and Offset Adjustment Knob: Moisture offset is used to do two things:
1. Calibrate the Combine Calc-U-Dri to your standard (the moisture tester used where you sell grain);
2. Adjust the moisture readout for grains other than corn.
• Short Average Display: Pull this switch down to see the short term average moisture displayed on the liquid crystal display. Push the switch up and hold until the beeps stop (four audible beeps will sound) to reset the average. Resetting the short average does not affect the long average.
• Average On Light: This light will be on whenever the averaging switch indicates the presence of grain. This light confirms that averaging is taking place.
• Liquid Crystal Display: Usually mounted on the combine steering column, this display shows temperature corrected grain moisture, temperature (when the switch is pushed up) and shows the operator what moisture limit is being set. The red light at the bottom of this display will light up whenever the moisture of the grain being harvested reaches or exceeds the moisture limit (as set by the operator).

Unique sensor designed for durability and reliability
Calc-U-Dri's stainless steel sensor is simple and uses capacitance-type sensing to accurately calculate grain moisture.

All readings are temperature corrected. Sensors are usually mounted in hopper fill augers. All grain must pass through this confined space, thus allowing Calc-U-Dri to give the most accurate moisture reading possible.
