seven-segment display

This product hasFive 8-segment digital tubes are used as display interfaces, which can display numbers and English letters. When combined with buttons, they can complete the functions of product information display and parameter setting. Please refer to Appendix A for the display effect of the digital tube.

image1 shows the basic interface operation process of the product.

After the product is powered on, it defaults to the main interface and displays the current measurement results in real-time. When pressedWhen ENTER, enter the menu selection interface; On the menu selection interface, use the up and down buttons to switch between 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, use the up, down, left, right buttons to modify the parameters, and then pressENTER or ESC returns to the menu selection interface (if ENTER is pressed to save changes, if ESC is pressed to undo changes).

Main Interface

LordThe interface is the measurement result display interface, which displays the current measurement result in meters after the decimal pointThree people.

By default, the main interface will be displayed when powered on. Press the buttonENTER switches to the menu selection interface. Press ESC on the menu selection interface to switch back to the main interface.

Zero position correction

Select through the up and down keys on the menu selection interfaceCALIB， Press ENTER to enter the zero position correction interface. At this point, the interface displays the calibrated data, which is updated in real-time by adjusting the calibration values.

Fix this product onto the test rail through the positioning hole and place it at a certain distance from the positioning hole (e.gPlace obstacles within 1 meter. Modify the calibration value by pressing the up, down, left, and right buttons to make the displayed data on the interface match the actual distance (such as 1 meter). Up and down keys increase or decrease the calibration value; Use the left and right keys to modify the amplitude of the calibration value increase or decrease, and the modified number will be indicated by flashing.

After the calibration is completed, pressENTER will display the current data used for calibration. At this point, you can also use the up, down, left, and right buttons to adjust the calibration data, using the same method as above. Press ENTER again to complete zero position correction; If ESC is pressed, the modification will be undone and the menu selection interface will be returned.

Sampling mode setting

To cope with different application scenarios, this product supports the following4 sampling modes.

Slow mode is used for precise measurement of 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.

Sampling mode	Data sampling frequency	Calculate the amount of data used
Slow speed（1.SLOW）	5Hz	8
Normal（2.NORM）	10Hz	8
fast1（3.FST1）	20Hz	4
fast2（4.FST2）	30Hz	2

Sampling mode description

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 driving relay will activate.

working mode	Lower limit of normal range	Upper limit of normal range
pattern1（1.mod1）	0	limit3（Limit3）
pattern2（2.mod2）	limit2（Limit2）	limit3（Limit3）
pattern3（3.mod3）	(limit1+limit2)/2	(limit2+limit3)/2

Working mode description

Select the working mode setting interface on the menu selection interface, use the up and down keys to select the desired working mode, and pressEnter to confirm the modification. If you want to undo the modification, press ESC to directly return to the menu selection interface.

Note: Limit1, limit2, and limit3 must be set in ascending order, with limit3 being the largest and limit1 being the smallest

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

Limit setting

fromSelect the menu selection interface to enter the limit setting interfaceThree limit parameters can be set, which are determined by 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 results, and zero

Enter the limit setting interface from the menu selection interface, which displays the current measurement results. Press directly at this timeENTER， Select system configuration as the initial value for fine-tuning and enter the fine-tuning phase; Press the up button (or left button) to use the current measurement result as the initial value for fine-tuning and enter the fine-tuning phase; Press the down key (or right-click) to set zero as the initial value for fine-tuning and enter the fine-tuning phase.

Fine-tuning phase

In the limit adjustment stage, adjust the size of the limit by pressing the up and down keys, and change the amplitude of the adjustment by pressing the left and right keys.

After the fine-tuning is completed, pressENTER saves the modifications and returns to the menu selection interface. Press ESC to undo modifications and return to the menu selection interface. If the limit value still needs to be set at this time, press ENTER in the menu selection to enter the initial value selection stage again and complete the subsequent operations.

range setting

This product can be set to different ranges according to requirements. The currently supported ranges are 1m, 3m, 5m, 10m, 15m, 20m, and 30m. Analog output corresponds to 10V output at full scale, and 0m corresponds to 0V output.

Select the range setting interface from the menu selection interface and use the up and down keys to choose different ranges. pressENTER saves the modifications and returns to the menu selection interface; Press ESC to undo the modifications and return to the menu selection interface.

Restore factory settings

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