1. Clamp-type Grain Moisture Rapid Tester Product Introduction:
This clamp The Grain Moisture Rapid Tester is a high-sensitivity, resistive grain moisture rapid testing instrument. It uses a single-chip microcomputer for measurement, non-linear conversion and power control, and the circuit design is advanced and reasonable. The moisture display mode adopts liquid crystal digital display, and the temperature correction is automatically performed, reducing the trouble caused by manual temperature compensation. This clamp-type grain moisture rapid tester has the characteristics of stable reading, intuitive, convenient, high measurement accuracy and fast test speed. At the same time, the circuit adopts various ways to reduce the working current and greatly reduce the power consumption of the whole machine. This machine adopts four universal Dry-saving batteries are used as power sources, which are easy to replace and easy to carry. One machine can measure seven grain varieties, and is suitable for the needs of grain purchase, storage and transportation in grain-producing areas across the country.

6. How to use:
According to the type of grain to be measured, select Corresponding sensor and connect it to the instrument
Turn on the power switch, the display will show the current grain type, and the whole machine will enter the working state.
According to the type of grain being tested, refer to the table on the instrument panel. Set the grain category to the corresponding number. The way to change the grain type is to press and hold the grain button for 3 seconds. After hearing a long beep, the grain number flashes. At this time, press the grain button again to change the grain type. After stopping pressing the button for 3 seconds, the number of grains will flash. You can hear a long beep again, and the change of grain type is completed. Insert the sensor mouth into the grain, and take samples according to the sampling standards on the instrument panel. Be careful not to touch the sample with your hands.
After taking the sample, clamp the clamp handle tightly so that the positioning pin is in contact with the contact point and kept (must be kept until new data appears). At this time, the data on the display disappears and will reappear later. The data is displayed. The new data is the result of this measurement, which is the moisture value of the measured grain sample. This moisture value includes temperature compensation, and there is no need for manual temperature compensation calculation.
The instrument will automatically shut down after being idle for an hour.
, Flood beep indication:
Short beep: normal operation
Short beep: The battery is low
Short beep: Indicates that the pliers were released before the instrument measured the results. ,
Long beep: Enter or exit the grain modification state.
7. Notes on relevant instructions:
The setting of grains and the selection of pliers must be consistent with the table on the instrument panel.
The clamp-type grain moisture rapid measuring instrument has two clamp-type sensors. When measuring wheat, rapeseed, japonica rice, and indica rice, the plastic clamp handle is yellow and the pliers with a shallower tray are used to measure corn, soybeans, and corn. The plastic pliers handles are red. Tongs for deep serving dishes.
Before each test, the attached tools should be used to remove debris and excess grains from the jaws.
Since grains in different regions are affected by factors such as soil composition, temperature, sunshine time, growth period, drought and floods, their physical parameters will also be different, and errors will occur when reflected in the test results. In view of this, In this case, the instrument is specially equipped with an adjustment knob for the user. There are seven adjustment holes on the left side of the instrument, and they are numbered. The numbers correspond to the grain setting numbers. If you find that there are errors in instrument testing or errors caused by other factors, you can adjust the corresponding knob. When you adjust it clockwise, the data will increase, and vice versa. At the factory-set position, the up and down adjustment can increase or decrease the moisture content by about . It must be noted that the data will not change immediately after the knob is adjusted, and will not be reflected until the next measurement. When adjusting, find another small flat-blade screwdriver. The random tool is used to remove grains from the jaws.
Since the clamp-type rapid grain moisture tester has the function of automatic temperature compensation, it is normal for the base number (that is, the data when measuring in the air without placing the grain) to change with the temperature. On the other hand, the base number is also related to the humidity of the air. , when the air humidity is very high, especially when it exceeds, the base number will increase significantly, but this increase will not affect the accuracy of the test. As long as the moisture content of the measured grain is greater than the base number, the test results will be correct.
Because the grain particles are large and small, the distribution of moisture in the grain grains is uneven, and there are impurities in the grain, the temperature of the instrument is inconsistent with the temperature of the grain being measured, the air humidity is too high, and sampling Failure to wait will cause the test results to fluctuate by a few tenths, which is normal.
The following methods can improve the accuracy of test results:
Take samples strictly in accordance with the sampling standards
Let the instrument and grain equilibrate at the same temperature for a long enough time (stability ratio of grain physical properties
/>The temperature equilibrium is much slower)
Remove impurities in the grain sample
Avoid testing in an environment with high air humidity.
8. Instrument supporting equipment:
, one instrument, two small cross screwdrivers for clamp-type sensors, one instruction manual, one product certificate, and one instrument packaging jacket.
9. Maintenance and maintenance:
If the sensor does not start after being held to the end, it is usually because the starting contact on the sensor is in poor contact or disconnected.
. When this clamp-type rapid grain moisture analyzer is not used for a long time, be sure to remove the battery. Circuit boards soaked in battery fluid cannot be repaired.
During use, try to avoid dust entering the instrument through the ventilation holes. Too much dust inside will cause the insulation performance of the instrument to decrease.
, Clamp-type grain moisture rapid tester has undergone strict calibration inspection before leaving the factory. Please do not disassemble it at will. Except for the error adjustment knob, other components in the circuit are strictly prohibited to be adjusted at will
, instruments, sensors It should be kept clean and dry, and severe vibration should be avoided. The sensor should be strictly avoided from knocking, bumping, and knocking to prevent deformation of the clamp body
. The clamp-type grain moisture rapid measuring instrument has been used for a long time, and the teeth of the upper and lower teeth of the sensor have been sharpened. If the gear is blunt and causes low measurement data, the gear should be replaced. If it is too late to replace it, the error adjustment knob can be adjusted to roughly compensate.
10. After-sales service:
Within one year from the date of shipment, the user must use this product in compliance with the requirements specified in the instruction manual. If the product is found to be faulty due to its own quality problems, the manufacturer will The manufacturer will repair it free of charge, but if the circuit board is scrapped due to battery fluid, the manufacturer will not bear the material cost.
