Road continuous pavement smoothness meter operation method

Road continuous pavement smoothness meter operation method

(1) Preparation for commissioning

1. The instrument test vehicle has two states, one is storage and transportation status, and the other is measurement and detection status. During transportation, remove the fixing bolts, retract the front telescopic square tube and the rear telescopic square tube in the middle, fix them with screws, suspend the measuring wheel, and remove all the plugs. When testing the test state, remove the fixing bolts, the frame is stretched into position, and then bolted and lowered the measuring wheel to make it close to the ground.

2. Install the printing paper.

3. Connect the cables and pay attention to the direction when connecting the cables.

Road continuous pavement flatness meter using steps

1. Set the parameters to correctly set the parameters, select the function 2 settings under the menu, press <INPUT> to confirm:

Indicates the road number, mileage number, starting station number, limit excess value; sampling interval (5cm × 2 = 10cm), the limit error value is manually set, the setting range is from 00~99mm; the sampling interval N01 means every 5cm In the second case, N02 means that every 10cm is taken as a sample, and so on, different sampling intervals can be input. Under normal circumstances, N02 is set according to the specification, that is, every 10cm can be sampled. Use the numeric keys to input each parameter. Each time you input a parameter, the cursor will automatically move to the next parameter. If the input is incorrect, only the parameter setting input data will be reselected. After the entire data is input, the setting parameters can be exited unless the button is pressed.

2. Before clearing the displacement sensor and then detecting it, press the clear key to clear the sensor.

3. Before detecting the sensor, determine whether the displacement sensor works normally. Select function 3 under the menu and press the button to confirm. At this time, the displacement sensor real-time value will be displayed on the screen.

4. The file is automatically stored as a record every 1000 sample points during the test. 256 records can be stored continuously. To ensure that there is enough memory, each test road can clear the original record before the test. Select the menu function. 7 Delete, confirm with the key, the screen is deleting.

5. Start testing After the above three steps are completed, the test can be started. The button can start working. The screen has real-time display of sampling points. When 1000 points are filled, the set station number and mileage number are automatically accumulated, and the calculation result is calculated. It is also displayed that these parameters and calculation results are automatically saved as a record, and the button ends detection.

6. Processing results After the test is completed, you can print the results. Select 6 to print all or part of the recorded results under the menu. Alternatively, use the 5 display function under the menu to display the saved records and display some or all of them.

7. After the test is finished, turn off the power, remove the connecting cable, and store the instrument in a dry and cool place.

Road continuous pavement flatness meter use precautions

1. If the instrument is not used for a long time, it should be charged once every 2-3 months to ensure that the battery is not damaged.

2. Before each use, it should be fully charged (usually charging for about ten hours).

3, flatness meter is a precision electronic instrument, such as sensors, meters, printers and other components, do not rain, damp, should be properly kept when not in use, regular power, to avoid damage.
