In shutdown state, the current of the whole machine is less than 0
1 μ a, and the measured value is 0
03 μ a;
b
In the startup state, the current of the whole machine is less than l Ma, and the measured value is 0
6 to 0
7 ma
C
In the test state, the current of the whole machine is less than 5 mA, and the measured value is about 4
5 Ma, which is consistent with that of grain
The current duration is 0
5 seconds for each measurement

3、 Power supply: 2# four dry batteries, 1
5V * 4 = 6V
4、 Operating temperature range: 20-45 degrees
5、 Volume: 290 * 180 * 65? Weight: 2kg
6、 Usage:
1
According to the grain variety to be measured, select the corresponding sensor and connect it with the instrument;
2
Turn on the power switch, the display screen displays the current grain, and the whole machine enters the working state,
3
According to the tested grain variety, set the grain type on the corresponding number with reference to the table description on the instrument panel
The method to change the grain category is to press and hold the grain category key for 2 seconds
After hearing a long sound, the grain category number flashes
At this time, press the grain category key again to change the grain category
After stopping pressing the key for 3 seconds, you can hear a long sound again, and the change of grain category is over;
4
Insert the material port of the sensor into the grain and take samples according to the sampling standard on the instrument panel
Be careful not to touch the sample by hand

5
After taking the sample, clamp the tong handle tightly to make , The pin contacts with the contact and keeps it (it must be kept until the new data appears)
At this time, the data on the display screen disappears, and the data will be displayed again later
The new data is the result of this measurement, that is, the moisture value of the measured grain sample
This moisture value has been included in the temperature compensation, and there is no need for manual temperature compensation calculation

7
The instrument will shut down automatically after being idle for 1 hour

8
Flood alarm indication:
(1) Short & ldquo; Tick: Normal operation;
(2) Short & ldquo; Didi & rdquo;: Insufficient battery power;
(3) Short & ldquo; Didi didi: It means that the pliers were loosened before the instrument measured the results,
(4) Long & ldquo; Tick: Enter or exit grain modification status

7、 Notes:
l
The setting of grain and the selection of pliers must be consistent with the table on the instrument panel

2
Clamp grain moisture , The measuring instrument has two clamp sensors
When measuring wheat, rapeseed, japonica rice and indica rice, the plastic clamp handle is yellow, and the clamp with shallow material holding plate: when measuring corn, soybean and corn, the plastic clamp handle is red, and the clamp with deep material holding plate

3
Before each test, the attached tools shall be used to remove the sundries and excess grains in the jaw

4
Due to the different effects of soil composition, temperature, sunshine time, growth period, drought and flood and other factors, the physical parameters of grains in different regions will also be different, and errors will appear in the test results
In view of this situation, the adjustment knob is specially set for the user on the instrument, and there are seven adjustment holes on the left side of the instrument with numbers, The number corresponds to the grain setting number
If there are errors in instrument test and errors caused by other factors, adjust the desired knob
When adjusting clockwise, the data increases, otherwise it decreases
At the factory set position point, up and down adjustment can increase or decrease about 2
0 moisture
It must be noted that the data will not change immediately after the knob adjustment, and can be reflected in the next measurement
When adjusting, find another small flat screwdriver
The random tool is used to remove the grain in the jaw

5
Due to clamp grain moisture , The tester has the function of automatic temperature compensation, and the change of base number (i
e
the data without empty grain measurement) is normal; On the other hand, the base number is also related to the humidity of the air
When the air humidity is very high, especially more than 85%, the base number will increase significantly, but this increase will not affect the test , As long as the moisture of the tested grain is greater than the base number, the test result is correct

6
It is normal that the test results will fluctuate by a few tenths of a point because the grain particles are large and small, the distribution of grain moisture is uneven, there are impurities in the grain, the instrument temperature is inconsistent with the measured grain temperature, the air humidity is too high, and the sampling is inaccurate

7
The following methods can improve the accuracy of test results , Degree:
(1) Take samples in strict accordance with the sampling standards;
(2) Let the instrument and grain balance at the same temperature for a long enough time (stability ratio of grain physical properties)
Its temperature balance is much slower)
(3) Eliminate impurities in grain samples
(4) Avoid testing in an environment with 85% dry air humidity

8、 Instrument matching:
1
One instrument; 2
Two clamp sensors; 3
A small cross screwdriver; 4
One manual; 5
One qualified product; 6
One instrument packaging jacket

9、 Maintenance:
l
The sensor does not start after holding it to the bottom
Generally, the starting contact on the sensor is in poor contact or disconnected

2
This clamp type grain moisture , When the tester is not used for a long time, be sure to take out the battery
The circuit board that has been vacuumed by the battery cannot be; Repair

3
During use, try to avoid dust entering the instrument from the ventilation hole
Too much dust inside will reduce the insulation performance of the instrument

4
Clamp grain moisture , The tester shall undergo strict calibration and inspection before leaving the factory
Do not disassemble it at will
Except for the error adjustment knob, other components in the circuit shall not be adjusted at will;
5
The instrument and sensor shall be kept clean and dry to avoid violent vibration
The sensor shall strictly avoid knocking, bumping and knocking to prevent the deformation of the clamp body
6
Clamp grain moisture , When the measuring instrument has been used for a long time and the tooth edges of the upper and lower tooth blades of the sensor are blunt, resulting in low measurement data, the tooth blades should be replaced
If it is too late to replace, the error adjustment knob can be adjusted to roughly compensate

10、 After sales service:
Within one year from the date of delivery, the user shall use the product in accordance with the requirements specified in the operation manual
If the product fails due to its own quality problems, the manufacturer shall repair it free of charge
However, if the circuit board is scrapped due to battery liquid, the manufacturer shall not bear the material cost
In case of failure after one year, the manufacturer will only charge material fees
If the fault of our products cannot be eliminated, please send the products to our factory, and our factory will provide users with good after-sales service
