1. Install the dry battery, please confirm that the "+" and "-" poles of the dry battery are facing in the same direction as indicated.

2. Due to the electronic balance inside the measuring instrument, please place it on a level surface without wind or vibration for use. If this measuring instrument is used handheld or placed in a windy and vibrating area, it will affect the measurement accuracy and may even be unable to measure.

3. Measure the temperature of the sample and the temperature of the instrument after sufficient fusion.

4. The use of automatic hopper: In order to ensure that the measured samples can be evenly fed into the measuring section, the grain moisture tester is equipped with an automatic hopper, which must be used for filling during the measurement.

IIGrain moisture testerThe determination

1. Connect the power supply. Press the power button. The screen will display the model of the local instrument, wait for three seconds

2. Select variety: Determine the sample code as shown in the table above. Press the [Select] button, and each time you press it, the variety number will increase by one. After variety number 12, it will return to 1. (The determination method for peanut kernels is different from other varieties and will be separately stated at the end of this regulation).

3. Secure the bottom cover of the automatic hopper, remove it from the main unit, slowly and evenly pour the sample into the automatic hopper until it overflows the cup, then move the hopper horizontally and scrape off excess sample to make it fill a cup flat.

4. Install the automatic hopper cup body on the instrument with the positioning groove cut forward. The instrument is equipped with an electronic balance. Please install the pedestal correctly and do not touch the non ring cover on the instrument to avoid affecting the measured value,

5. Press the 'Measure' button. At this point, the decimal point is flashing. Please note that the electronic balance is currently undergoing zero point adjustment, so do not touch or vibrate this instrument. When the 【 POOR 】 starts flashing, press the automatic hopper button, and the valve at the bottom of the automatic cup will automatically open, allowing the material to be instantly poured into the instrument. After disappearing and the decimal point flashes 4 times, the instrument screen will display the moisture value and measurement times. Note that when the moisture value exceeds the measurement range, it will display "FFF" if it is higher than the measurement range; When it is lower than the measurement range, it will display "AAA".

6. Pour out the sample, pull the gate of the automatic hopper forward to close, restore the bottom to its original state, and remove the automatic hopper and pedestal from the measuring instrument. Then pour out the sample, keeping the moisture value constant, and continue measuring from step 3.

7. The display of the average value, when the number of measurements is between 2-9 times, pressing the 【 Average 】 button will display the number of measurements and the average value. After pressing the 【 Average 】 button again, the display of the next moisture measurement will start from 1.

3、 Determination of Peanut Kernel

The determination of peanut kernels does not use an automatic hopper

1. Place the hopper over the sample cup and slowly pour in the sample until it overflows from the cup. Move the hopper horizontally and hang off any excess sample to fill the cup (this step is the same as 3)

2. Press the 【 Select 】 key several times to display the variety name as' 8PEAN 'representing peanut kernels

3. Press the [Measurement] button, and the decimal point will flash several times. After the "POOR" flashes, start pouring the sample. Use a cup to quickly pour the sample into the measurement cell. After the "POOR" flashes stop, do not continue to put it in. At this time, make the surface of the sample horizontal. 4. The "POOR" disappears, and after the decimal point flashes four times, the moisture value and measurement times will be displayed. If the repeated measurement starts from 1.

4、 Correction method for moisture value

The moisture values of various varieties can be corrected within the range of -9.9% to+9.9%, which is used to input the correction value when the results do not match the standard method. Input mode for correction value:

1. Confirm that the power is turned off, press the [Switch] button to display the "Model" and other content. During this period, press the [Select] button continuously until all displays disappear and the "BIAS" correction value "%" is displayed. The initial value of the correction value is 0.0%

2. Select the variety, press the [Select] button. Each time you press the [Select] button, the variety number will increase by one

3. When increasing the correction value, please press the "Measure" button. Each press will increase the correction value by 0.1%. When decreasing the correction value, please press the "Average" button. Each press will decrease the correction value by 0.1%. The correction value will be automatically saved. After the power is turned off, the correction value will also be automatically saved

5、 Shut down

VIGrain moisture testerTesting precautions

1. Thoroughly clean the measuring cell with water. If there is dust or foreign matter in the measuring cell, please wipe it with dry gauze or cotton balls.

2. The gate of the automatic hopper will forcefully pop out during unloading, please be careful not to touch your hands to avoid injury.

3. When the instrument displays "POUR", it is the sample entry time. When "POUR" disappears, pouring cannot continue, otherwise the instrument will not be able to measure correctly.
