Instructions for use

The user interaction interface of this product mainly consists of digital tubes, LED indicators and buttons. Digital tubes and LED indicators are used to display product information, and buttons are used to modify product parameters.

LED

This product has 5 LED lights to display the basic status of the product. See the table below for detailed instructions.
 
 

button

This product has a total of 3 physical buttons. By short pressing and long pressing, six virtual buttons are created, namely up, down, left, right, confirm, and return.

Notice:

1. The corresponding event will be triggered only after the button is pressed and released.

2. A short press means pressing for 0.2~0.5 seconds and then releasing it; a long press means pressing for more than 0.5 seconds and then releasing it.

Digital Tube

This product has five 8-segment digital tubes as the display interface. The digital tubes can display numbers and English letters, and can be used in conjunction with the buttons to complete the functions of product information display and parameter setting. Please refer to Appendix A for the display effect of the digital tube.

Figure 1 shows the basic interface operation process of the product.

After the product is powered on, it enters the main interface by default and displays the current measurement results in real time. When ENTER is pressed, the menu selection interface is entered; in the menu selection interface, use the up and down buttons to switch submenus, and press ENTER to enter the corresponding submenu interface. Press the ESC button on the menu selection interface to return to the main interface.

In the submenu interface, after using the up, down, left and right buttons to modify the parameters, press ENTER or ESC to return to the menu selection interface (if you press ENTER to save the modification, if you press ESC to undo the modification).

Main interface

The main interface is the measurement result display interface, which displays the current measurement result in meters with 3 decimal places.

The main interface is displayed by default after power-on. Press ENTER to switch to the menu selection interface. Press ESC on the menu selection interface to switch back to the main interface.

  Zero correction

In the menu selection interface, use the up and down keys to select CALIB, and press ENTER to enter the zero calibration interface. At this time, the interface displays the corrected data. By adjusting the calibration value, the interface updates the correction data in real time.

Fix the product on the test rail through the positioning hole, and place obstacles at a certain distance (such as 1 meter) from the positioning hole. Use the up, down, left and right buttons to modify the calibration value so that the data displayed on the interface is the same as the actual distance (for example, 1 meter). The up and down keys increase or decrease the calibration value; the left and right keys modify the amplitude of the increase or decrease of the calibration value, and the modified number will be prompted by flashing.

After the calibration is completed, pressing ENTER will display the data currently used for calibration. At this time, you can also use the up, down, left and right buttons to adjust the correction data, the method is the same as above. After pressing ENTER again, the zero position calibration will be completed; if ESC is pressed, the modification will be canceled and the menu selection interface will be returned.

Sampling mode setting

In order to cope with different application scenarios, this product supports the following 4 sampling modes.

Slow mode is used to accurately measure the distance to stationary objects, characterized by high accuracy and slow response speed; fast mode is used to measure fast-moving objects, characterized by fast response speed and reduced measurement accuracy.

Working mode setting

This product supports relay over-limit alarm output. Set the normal working range of the product by setting the working mode; when the measurement result exceeds the normal range, the drive relay will act.

Working mode description

In the menu selection interface, select to enter the working mode setting interface, select the required working mode through the up and down keys, and press ENTER to confirm the modification. If you want to undo the modification, press ESC to return directly to the menu selection interface.

Note: 1.limit1, limit2, limit3 must be set in order from small to large, limit3 is suitable for large, limit1 is suitable for small

2. If limit1, limit2, and limit3 are not set in ascending order, they will be reordered when calculating the range.

Limit setting

Select from the menu selection interface to enter the limit setting interface. There are three limit parameters that can be set. Which limit parameters to set are determined according to the working mode.

The setting of limit parameters is divided into two stages: initial value selection stage and fine-tuning stage.

 
Initial value selection stage

The initial value of the limit parameter can be obtained from three sources: system configuration, current measurement result, zero

Enter the limit setting interface from the menu selection interface, which displays the current measurement results. At this time, directly press ENTER, select the system configuration as the initial value of fine-tuning and enter the fine-tuning stage; press the up key (or left key) to use the current measurement result as the initial value of fine-tuning and enter the fine-tuning stage; press the down key (or right key) ) Set zero as the initial value of fine-tuning and enter the fine-tuning phase

。
 
fine-tuning phase

In the limit fine-tuning stage, use the up and down keys to adjust the limit size, and use the left and right keys to change the fine-tuning amplitude.

After fine-tuning is completed, press ENTER to save the changes and return to the menu selection interface. Press ESC to undo the modification and return to the menu selection interface. If you still need to set the limit value at this time, press ENTER in the menu to enter the initial value selection stage again, and complete the subsequent operations.

Range setting

This product can be set to different measuring ranges according to needs. Currently supported measuring ranges are 1m, 3m, 5m, 10m, 15m, 20m and 30m. The full scale of the analog output corresponds to 10V output, and 0m corresponds to 0V output.

In the menu selection interface, select to enter the range setting interface, and use the up and down keys to select different ranges. Press ENTER to save changes and return to the menu selection interface; press ESC to undo changes and return to the menu selection interface.

Factory reset

In the menu selection interface, select to enter the factory reset interface, and use the up and down keys to switch between YES and NO. When YES is selected, pressing ENTER will restore the factory default configuration and return to the menu selection interface; when NO is selected, pressing ENTER or ESC will directly return to the menu selection interface.
