SEEDBURO is now launching Model DMC750 Digital Moisture Meter. This revolutionary moisture meter has been designed to provide a direct and accurate reading of the Moisture Percentage.

With a simple, operator-independent operation, the DMC750 will provide you with a moisture reading within a few seconds for a wide range of products.

With a simple keyboard, fitted with 5 keys only, it is easy to operate the instrument and promptly perform the setup, no long training being required from the user.

The DMC750 allows a moisture analysis to be performed using the fully automatic FLOW-THRU technology. There is no need to pre-weigh the sample, and the temperature correction can be automatically performed without using any other resource or additional tables.

The calibration curves for each cereal were obtained in the laboratory using samples collected from various harvest areas. The measurement scales for each product were created using the standard oven method as a reference. These curves were transferred to the DMC750 memory and are easily identified by the product name. There are no limits to curves that can be stored in the DMC750 memory.

The DMC750 consists of three instruments in one, managed by an internal state-of-the-art microprocessor, and its program performs all required calculations and provides extremely reliable and repetitive readings. It further performs the automatic adjustment and checking of the proper operation of all the electronic circuits. These three instruments are: an electronic scale that measures the sample weight, an embedded digital thermometer that measures the sample temperature inside the chamber. And, finally, a capacitance meter which indicates the moisture percentage which will be corrected further ahead according to the other parameters. The FLOW THRU instrument is designed in such a way to allow for quick measurements to be performed, that is, in less than 15 seconds, without the operator interference. Simply select the product, pour the sample into the DMC750 funnel until a beep sound, and the instrument will load the sample, perform the measurements, and automatically unload the product; and after a few seconds you will have the sample

MEASURE Function, Measuring Moisture

1- Connect the Converter to the moisture meter rear panel connector, and there is no need to be concerned with the line selection as the converter is FULL RANGE and operates on line voltages between 90-240 VAC.

2- The message “A power failure occurred” appears indicating that an outage occurred on the power to the DMC750. This message can be cleared by simply pressing the ON/OFF button.

3- Press the ON/OFF button on the instrument front panel to turn the DMC750 on. At this moment start a series of self-tests so as to check the operation of all components. If the instrument possibly detects that one of its components is not operating properly, it will present a message on the display indicating what fault has occurred. This fault should be reported to SEEDBURO’s Technical Assistance. This step takes approximately 10 seconds.

4- Allow the DMC750 meter to preheat for 10-15 minutes. The DMC750 should be ON and operate continuously all day long; unplugging the Adapter is not recommended. The DMC750 should be operated in a place free from excess dust, with a room temperature between 5ºC and 45ºC.

5- Then select the cereal type of which you want to know the moisture. Keep pressing the RIGHT and LEFT arrows until finding the desired product, and press YES to confirm the choice.

6- Take a sample of the product of which you want to measure the moisture by using the Plastic Spoon, and slowly pour the cereal sample into the Loading Funnel until the 100% indication appears on the display and a beep sounds, indicating that the sample weight is correct. If the weight is possibly exceeded, the display will indicate a value greater than 100%, and the excess sample should be removed from the sample funnel.

OPERATION

10

7- After 10 seconds, the DMC750 will display the Product Moisture Value. If you press the RIGHT or LEFT arrow keys, the DMC750 will display all measures taken, that is:

• Product • Sample Moisture % • Product temperature in the chamber. • Sample Number.

Once the measurement is successfully taken, the DMC750 will send all measurement data via the serial output to a printer or computer.

Note: In case there is a significant temperature difference between the product and the DMC750 chamber, it will wait until a thermal balance between the two is reached, and this may cause the temperature measurement to take longer to perform.

8- When the DMC750 is showing the measurement results on the Display, and the YES key is pressed, or a new sample is poured into the funnel, the DMC750 will perform a new measurement using the same configuration of the previous measurement. If the ESCAPE key is pressed, the MEASURE option will be quitted, indicating the products again.

9- After the measurement cycle, the instrument unloads the sample into the Drawer, from where it must be removed by the operator.

Note: Due to the trend that some products have to accommodate unevenly in the chamber, it is recommended to perform an average of 3 readings, such as for example rough rice or corn with moisture content higher than 25%.

The following is a block diagram intended to help understand the screen flow on the DMC750.

SETUP

Hard Lock (Switch)

Serial Output

Attention: All functions described as of here can only be accessed with the Hard Lock switch installed on the DMC750 serial output. Do as follows:

1- Turn the DMC750 off from the line, disconnecting the adapter cable from the rear panel.

2- Connect the Hard Lock to the serial output.

3- Connect the power cable again and press ON/OFF twice so as to set the DMC750 to service.

4- Now a menu appears with all configurable functions. Use the RIGHT/LEFT ARROW keys to choose the desired option and when you find it hit YES.

5- To disable these options again, disconnect the DMC750 from the power source, remove the Hard Lock and turn it on again; it will start to measure the moisture only.

Adjust function, performs zero adjustment

This option allows a correction to be made on the DMC750 moisture indications. The DMC750 leaves the factory calibrated by the standard oven method. The checking curves have been surveyed using a kiln as standard. But if necessary, however, an adjustment which shifts all the constant value curve, follow the procedures described below:

We wish, for example, that the DMC750 indicate an additional 0.5% to the current indication:

1- Select the ADJUST option from the menu, and press YES.

2- The DMC750 will indicate the current Zero value. It could for example be 0.0. The desired correction should be added to this value, in our example 0.5%. The new Zero value will then be 0.5%.

13

3- Set the value indicated on the display using the RIGHT/LEFT arrow keys to Zero = 0.5. Confirm pressing YES.

4- The GAIN value will appear, do not change this value as it should only be changed by the SELF-CALIBRATE function. Press YES.

5- Go to the MEASURE option and measure the moisture, and the DMC750 will indicate the moisture plus 0.5%.

Self-Calibrate function, readjusts the Moisture indication

The DMC750 leaves the factory using the oven method, but this option allows an adjustment to be made in the moisture indications on the DMC750, using two samples with their moisture value known, determined for example by a trustworthy standard or method. Follow the below described procedures:

1- Obtain a sample with the greatest difference in moisture possible. Such difference should be of at least 3.0%, as this will ensure a good curve adjustment; if lower, the DMC750 will not perform the adjustment.

2- The sample quality is very important. Prior to starting the tests, homogenize the sample; remove foreign matter such as bits, peels, chips, earth, etc. Do not forget that these two samples will adjust the equipment.

3- Perform the measurements with the standard, making at least three repetitions of each sample and calculating the average. Write down the values in order to subsequently report these to the DMC750. Keep the samples in a closed plastic bag so as to avoid changes in the moisture.

4- Look for the SELF-CALIBRATE function and press YES. The DMC750 will ask the LOW moisture sample and three repetitions will be made with this sample.

14

5. Upon completion of the 3 repetitions with the LOW moisture sample, the DMC750 will display the moisture value it measured and will ask what value it should indicate for this sample; inform the value obtained from the standard.

6. The DMC750 will ask for a HIGH moisture sample, and three repetitions will made with this sample.

7. Upon completion of the 3 repetitions with the HIGH moisture sample the DMC750 will display the moisture value it measured and will ask what value it should indicate for this sample; inform the value obtained from the standard.

8. With this data the DMC750 will perform all required calculations and, if everything is consistent, will write in the memory the ZERO and GAIN values for this product.

9. A report will be issued by the serial output with all the adjustment details, and the new ZERO and GAIN values will be reported in the end.

10. Now go to the MEASURE option and measure the moisture of the two samples on the DMC750, checking whether the error is at most 0.2% relative to the standard. The DMC750 is gauged.

We show beside an example of a report issued after a calibration.

There are the products called One to Five which can be used to measure a cereal having no own scale on the DMC750; the Self-Calibration function should be used to adjust the DMC750.

Serial Function, data output configuration

The DMC750 display, in this option, shows on its display what the current configuration of the Rs232C serial output is. This information should be used in order to program the PC, peripheral or printer being connected to the DMC750. Baud Rate: 4800 Bits: 7 Parity: Odd Stop Bit: 1 The below is an example of a report issued by the DMC750 after the measurement:

------------------------------- DMC750 Moisture Meter ------------------------------- Sample .......... = 62 ------------------------------- Date .............= 6/17/02 Time .............= 02:05 p.m. Product ..........= Wheat Temperature ......= 23.9 ºC ------------------------------- Moisture ........ = 18.9 % -------------------------------

Load function, stoppage or not of the loading funnel door

There are extreme instances where the cereal moisture is so high that an obstruction with the sample may occur on the input funnel, such as is the case with moisture around 30%. This option is intended for programming the loading funnel door stop during the cereal loading. The DMC750, during the loading, prompts you to press YES with the door open in order to inspect whether the whole sample has flowed into the chamber; if not, use a pen to clear the obstruction. The factory default is “Stop = OFF”.

Self-Diagnostics Function, DMC750 Status Report The purpose of this function is to allow the user to have a hard copy of the adjustment values for each scale of the DMC750, when one wishes to publish this gauging, carried out in a given laboratory, for other devices in other locations. Another reason is that in case there is any memory fault such information will not be lost, and once the device is recovered you just have to type in these values in order for it to return to its particular configuration.

It provides the Technical Assistance with data to evaluate whether the DMC750 is operating properly, once it has undergone the self-diagnostics when it is turned on.

Note that there are two frames, the first indicates the DMC750 operation, the second the programmed adjustments, and finally the last line shows the Firmware version installed on the device. There is an example report beside in this page.

The following indicated are the expected values for each item and its respective tolerance:

Sample: maximum 65535, then it returns to 0.

Product: product selected when the report is issued.

Temperature: Can be compared with the room temperature if the device has not performed any test for at least 1 hour. The admissible error is ± 0.5ºC.

Adjust RTC Function

The purpose of this function is to allow the user to adjust the date and time of the Real-Time Clock (RTC). The DMC750 clock is already factory adjusted, but it may possibly be readjusted. There is a battery that keeps the clock working even when the DMC750 is unplugged. The battery duration is above 5 years, and to test the battery simply turn the DMC750 off and notice if the clock starts indicating the 00:00:80 time. Should this occur, contact SEEDBURO Technical Assistance in order to replace the battery.

1- Turn the DMC750 on by pressing the ON/OFF key.

2- Press YES, on the “Adjust Clock” option.

3- Now use the RIGHT and LEFT arrows to increase or decrease respectively the TIME value and, when the value is correct, press YES.

4- Repeat this procedure to set the MINUTES, DAY, MONTH, and YEAR.

5- When the YES key is pressed after setting the YEAR, the DMC750 returns to the main menu.

And underscore appears below the value being set; after pressing YES, it moves to the next item to be set. This Date and Time value will be sent by the RS232 Serial output after the measurement.

20

MOISTURE TEST CAUTIONS

Extreme Conditions

Samples containing snow or ice will not be satisfactorily measured.

Frozen samples can be analyzed if they are allowed to heat in an airtight container in such a way to be close to the room temperature. Use an average value of 3 or more readings.

Below the 10ºC temperature range, perform 3 readings and use the average value.

Surface Moisture

Grains obtained from a storehouse with a warm interior, in contact with the moist air, develop surface moisture. The same equally occurs for some uncovered cereals during the rain, and these will keep the surface moisture for various days unless an artificial heat is applied in order to dry them. The surface moisture presents very low impedance for the high-frequency current flow and thereby a wrong reading will be obtained.

Moisture Measuring Processes

Usually, there are two methods for measuring the cereal moisture: primary and secondary. The primary method consists of a procedure using the air-oven. This procedure is time consuming and obviously would not be convenient. Due to this, the secondary method was developed in such a way to allow the cereal electrical properties to be quickly measured and converted to moisture reading.

Although technological researches and developments have been carried out on the electronics as well as on the understanding of the cereal properties, the cereal cannot possibly be analyzed without some variation. Some of the involved factors are discussed below.

We recommend that the product to be measured on the DMC750 be clean and free from any impurities that might interfere with the moisture measurement. We cannot forgo considering the fact that, during the instrument calibration process relative to the oven, a clean product has always been used.

21

The standard reference method used on the moisture meter calibration is the air-oven method in accordance of International Organization of Standardization (ISO).

The first problem concerning the cereal measurement is obviously the standard itself.

Not only we have different cereals such as wheat, barley, corn, soybean, rice, and others, but also a number of variations in each type of cereal.

Each cereal poses its own problem for measuring the moisture.

And new hybrid cereals are developed with the new efforts, and the electrical properties of these cereals can change slightly such as for example the volume and weight measurement.

We encourage your participation in the development of calibrations, and ask you to help us in our work by providing samples or products which calibration is in progress.

Error Messages

PLEASE, INCREASE SAMPLE or DECREASE SAMPLE

The quantity of sample used is out of the limits the DMC750 is capable of correcting and, for safety reasons, the DMC750 unloads this sample. Either increase or decrease the quantity of sample. MOISTURE TOO LOW! or TOO HIGH !

The DMC750 was calibrated using the standard oven method, and its precision is ensured within the range on which the tests were performed. When the measurement exceeds this range the DMC750 will display this message. We recommend that the calibration is made using the “Self-Calibrate” option on the “Product” scales, as these have 5% to 60% limits of moisture.

TEMPERATURE TOO LOW! or TOO HIGH !

This indicates that the sample temperature is below 5 ºC or above 50% − prior to performing the test wait for the temperature to balance with the environment.

SWITCH ABSENT! FUNCTION BLOCKED,

This message appears when we attempt to enter “Adjust” or “Self-Calibrate”, without the key that allows the access to this function.

When the DMC750 is turned on it performs a series of self-diagnostics that ensure the device will carry out the measurements with reliability. In addition to this test, a check will also be made at every measurement and if errors are found the following messages will be displayed:

23

CHAMBER OBSTRUCTED A certain amount of the sample may have been held in the chamber, and thereby the self-adjust limits are exceeded. Remove the drawer, turn the device on its back and slowly open the chamber door and clean the chamber using a brush. If the error persists, then a fault occurred on the instrument, and in this instance send the instrument to SEEDBURO’s Technical Assistance.

SCALE INOPERATIVE

The electronic scale is not operating properly, and this message indicates that a fault occurred on the DMC750 Electronic Scale. Send the DMC750 to SEEDBURO’s Technical Assistance.

TEMPERATURE TOO LOW! or TOO HIGH !

Indicates that the DMC750 temperature is out of the 5ºC to 50°C thresholds. If this is not true, then it indicates a fault on the thermometer, so send the DMC750 to Distributor Technical Assistance.

24

Maintenance

Cleaning

The routine maintenance will primarily consist in cleaning the moisture meter, keeping free from dirt and dust particularly the Chamber and the circuit boards. When products such as rough rice, soybean meal and citrus are measured, the chamber may accumulate refuses, especially when such cereals are too dry and the relative humidity is low.

Use a brush in order to expel the refuse and dust from the chamber and the loading funnel/scale. Be careful when performing the cleaning as the temperature sensor may be damaged.

25

Electronics

There will be a minimum number of reasons for faults as the moisture meter uses solid-state electronic components. The electronic circuit is contained in a printed circuit board located in the instrument side. Its operation is not sensitive to dust, and the micro-controller is capable of detecting any fault displaying an error message on the display. In the event a fault occurs, we recommend that the DMC750 is returned to SEEDBURO for the due repairs and recalibration.

Do not forget that every time the DMC750 is turned on the micro-controller performs a series of self-tests to ensure its optimum operation.
