EJSD soil compaction meter

EJSD series digital soil compaction tester

First, the function

EJSD digital soil compaction measuring instrument is also called soil solidity and hardness measuring instrument. It can be used to measure soil compaction in the field. Built-in GPS positioning and depth measurement system can simultaneously display soil compaction, measuring depth and Geographical location, the soil compaction curve of each measurement point can be automatically generated after being connected with the computer, and the regional soil compaction distribution map can be generated from multiple measurement points, and the relevant data link can be automatically generated. Tight soil can prevent the infiltration of water, reduce the utilization of chemical fertilizers, affect the growth of plant roots, and reduce crop yield. Therefore, it is particularly important to know the compactness of the soil, and this instrument can better guide agricultural production and highway construction.

Features

1. Portable in the field, high precision and high resolution, with the characteristics of simple operation, full functions and convenient carrying.

2. It can directly measure soil compaction. Built-in GPS positioning and depth measurement system can display the position information (latitude and longitude) of the measurement point to measure depth and soil compaction, and can store the data of each sample during the measurement to the host All data of up to 200 measuring points can be stored on the system.

3, with data upload function: use RS232 interface to connect with the computer, the software can automatically generate the soil compaction curve of each measurement point and regional soil compaction distribution maps can be generated from multiple measurement points and automatically generate related data links . The software has storage and printing functions.

4. It has the function of automatically grasping the peak value of soil compactness and backlight, environmental protection, and automatic shutdown function. (Without operating the monitor button, the monitor will automatically turn off after 10 minutes).

4. Resolution: 0.1Kpa;

5. Accuracy: ± 1%;

6. Operating temperature: -10 ℃ ～ 60 ℃

7. Output interface: RS 232 (nine-hole socket).

8. Power supply: rechargeable battery, charger (charging voltage 100V ～ 240 V)

9. Operating temperature: -10 ℃ ～ + 60 ℃;

10. Dimensions: outer diameter 140mm × height 750mm

User operation instructions

1. Operation steps and storage method for pressure measurement

a. Make sure that the display is connected to the sensor, and its \"F\" indication represents the force value (so-called sensor connector). Combined with the next step, as shown below:

b. Make sure that the data line of the displacement indicator is plugged into the display and connected, and its \"S\" indication represents displacement (also known as the sensor connector). Combined with the previous step, as shown below:

c. Turn on the power switch, display the manufacturer information and welcome to enter the user's main interface.

d. If the data is not zero, press the zero key.

e. According to soil measurement depth requirements, rotate the measurement handle smoothly and uniformly to the required depth

Press the save key to save the measurement data. (During measurement, the measured soil pressure and depth can be displayed in real time.

Degree of technical parameters. )

2. Query the saved data (when the data has been saved)

3, latitude and longitude (real time) view on the main interface of the display user

★ 4. Full-scale setting: The user is not allowed to use this setting.

5. Upload data

a. Connect the display and computer with R232 data cable first (as shown below):

b. Computer software operation steps

First open the box, find out the CD-ROM in the attachment, read it in the CD-ROM drive, double-click the file

This icon in.

c. Press the steps to operate the meter again.

d. At the same time as the previous operation, the computer software will pop up a dialog box. In this dialog box,

Fill in this data name and click OK.

6. Computer software operation method

a, view the distribution map: click the toolbar \"distribution map \" icon, the display effect is as follows:

b. The test data import operation is the same as the previous step:

① 、 View the imported data: Click on the toolbar \"Curve \" icon to pop up \"Data

Source \"dialog box, select the data you want to view under the file name column and click OK.

② Under the test position column on the right, select the one you want to display (or display at the same time)

Show multiple) data.

③ After selecting the data under the test position column, click the curve, and in the display window area

Display the curve of the data (if you click the value, the saved data will be displayed under the depth and compactness column.

Value).

c. The export operation of test data is as the previous operation method:

① 、 Double-click the blank area of ​​the display window area, and pop up\"Deep hardness curve customization ...\"

Dialog box, click Output at the bottom right of the dialog box.

② Select the required type in the dialog box of\"Output depth hardness curve\" and click

Output can be done (including printing, data report export, and curve image operations in this dialog box).

Eight, matters needing attention, maintenance and repair
