1. Product introduction:
This instrument is a high-sensitivity, wide moisture measurement range resistive moisture and temperature rapid measurement instrument. The highest measured moisture value can reach above. It is through the joint efforts of our factory's engineering and technical personnel. After conducting technical research and solving the technical problem that the resistance method cannot measure low and high moisture, we designed and developed it according to the national standards (opinion draft) for capacitance and resistance grain moisture measuring instruments issued by the State Administration of Quality Supervision, Supervision and Quarantine. , a new type of measuring instrument produced. The machine uses imported single-chip microcomputer for measurement, non-linear conversion and power control. The circuit design is advanced and reasonable, and the measurement data is displayed with LCD digital display. The readings are stable, clear, intuitive, and convenient. The temperature correction is automatically performed by the microcontroller, which reduces the trouble caused by manual conversion of temperature compensation. At the same time, the circuit uses a variety of ways to reduce the operating current, greatly reducing the The power consumption of the whole machine is reduced, and the power supply uses ordinary batteries, which is easy to purchase and replace. The instrument has a small size. It is light in weight, easy to carry, simple to operate, fast in testing speed and high in measurement accuracy. One machine can measure seven varieties of wheat, corn, soybean, rapeseed, sorghum, japonica rice and indica rice. It is suitable for grain, seeds, commodity inspection and processing all over the country. The procurement, storage, processing, and transportation of enterprises and other departments should be particularly suitable for the acquisition and processing of high-moisture grains in cold regions such as Northeast China and Inner Mongolia. Accurate measurement of grain moisture content can guide procurement and production.
2. Technical parameters:
, Measurement varieties: wheat, corn, soybean, rapeseed, sorghum, japonica rice, indica rice
, Measurement moisture range: wheat, corn, soybean, 3 rapeseed, 3 sorghum, japonica rice Indica rice
Main moisture range: wheat, corn, soybean, rapeseed, sorghum, japonica rice, indica rice
. Temperature measurement: 1℃℃.
. Measurement accuracy: The measurement error of the main moisture range is less than +/. The measurement error of other moisture ranges is less than +/1: The temperature measurement error is less than +/℃.
. Current consumption of the instrument: In the off state, the current of the whole machine is less than that of the on state, and the current of the whole machine is less than: In the test state, the current of the whole machine is less than, which is related to the moisture content of the sample being tested. It is measured once every time. The duration of this current is . seconds

℃℃
5. Volume and weight:
After packaging: weight
6. Instructions for use:
, Moisture measurement:
Take out the instrument and sensor, and connect the sensor to the instrument. .
Press the switch button, the display will display the number representing the grain type. It will be displayed after one second, and the whole machine will enter the test state
According to the grain type of the sample being tested, refer to the table description on the instrument panel, and the number of the grain to be measured will be displayed. Grain categories are set on the corresponding numbers. The method to set the grain number is: press and hold the variety button for 3 seconds and hear a long beep. At the same time, the number representing the grain type is displayed. This number is displayed in a loop. When the number of the grain type to be measured is displayed, release the button. After the display enters the test state, measurement can be carried out.
Unscrew the upper cover of the sensor and check whether the positioning pin of the sensor barrel is installed into the positioning hole of the outer cylinder base of the sensor (the positioning pin is the end of the spring of the sensor barrel). If it is not installed properly, it will not work. Take measurements. Must be reinstalled.
. Sampling standards: Use a spoon to evenly fill the barrel with the sample to be measured, and then smooth it after vibration. Close the upper cover, align the threads and screw them in evenly. You will hear a long beep and the numbers will disappear and stop. After a while, new data will appear. This data is the actual moisture value of the sample being tested. This moisture value includes temperature compensation. Inside. No need to manually calculate temperature compensation. The first measurement data of a tube of sample shall prevail, and other re-measurements will be invalid.
Pour out the sample from the barrel and use the tools provided to clean the barrel for reuse next time.
. Temperature measurement. Press the temperature key. The value displayed on the display is the current temperature value. For example, it represents ℃ above zero, and it represents ℃ below zero.
After the temperature measurement is completed, press the temperature key again. The display shows. The instrument enters the moisture test state
To change the temperature test environment, the instrument needs to be balanced for a certain period of time. After the instrument and the measured ambient temperature are balanced, the measurement can be performed again.
, The instrument will automatically shut down after being idle for several minutes,
, Flood sound indication. Short beeps for normal operation, conversion of grain types, and temperature measurement. When the long beep sample is tested, there will be three long beeps, beeps, and beeps, and the display number will flash at the same time, and then it will automatically shut down, indicating that the battery is insufficient and needs to be replaced with a new battery, otherwise it cannot continue to be used
Maintenance and maintenance:
. Check the sensor contacts frequently. If it cannot start or display, it is usually due to poor contact or disconnection of the sensor. Just tighten it
If the thread of the outer cylinder of the sensor is found to be difficult to twist or tighten during use, you can add a little grease to the thread to solve the problem.
. If the instrument is not used for a long time, be sure to remove the battery to prevent battery leakage. The circuit board soaked by battery fluid will not be repaired.
. When replacing the battery, be sure to use alkaline batteries and try to avoid using inferior batteries.
During use, avoid dust entering the inside of the instrument from the ventilation holes. Too much dust inside will reduce the insulation performance and affect the use.
The instrument has undergone strict inspection, calibration and debugging before leaving the factory. Please do not disassemble it at will. Except for the error adjustment knob, other components of the circuit are strictly prohibited to be adjusted at will.
, instruments and sensors should be kept clean and dry, avoid violent vibrations, and sensors should avoid bumps. To prevent deformation. Within one year from the date of purchase of this product, if the user uses it under the conditions stipulated in the instruction manual, if the product is found to malfunction due to its own quality problems, the manufacturer will repair it free of charge. However, if the malfunction or wiring is caused by battery leakage If the board is scrapped and cannot be eliminated, please send the product back to our factory. Our factory will provide you with good after-sales service.
