The level doesn t light up, the level doesn t alarm, what s going on?

1.The switch knob is not rotated all the way down.

2.Open the case and check whether the copper wire is desoldered. In general, there is a horn sound after the battery is on, but there is no light on, which belongs to this kind of situation.

3.Battery box - check whether the wire is broken and whether the spring is in good contact with the battery.

4.Test the switch circuit to see if the micro switch is energized, if it is energized, it means that there is no problem with the switch, if it is not energized, please replace the micro switch.

5.The circuit motherboard, the above problems are checked well, then the motherboard has to be replaced.

6.The horizontal line of the laser tube is not bright: first check to see if the copper wire is broken, and then see if the lower pair is lit, if the lower point is not lit, you have to remove the black wire on the last line of the wiring board, and the horizontal line is good.

A spirit level is a commonly used measuring tool for measuring small angles. In the machinery industry and instrument manufacturing, it is used to measure the inclination angle relative to the horizontal position, the flatness and straightness of the guide rail of machine tool equipment, the horizontal position and vertical position of equipment installation, etc. The leveling tube of the level is made of glass, the inner wall of the leveling tube is a curved surface with a certain radius of curvature, the tube is filled with liquid, when the level is tilted, the bubbles in the level tube move to the raised end of the level, so as to determine the position of the level.

Do my best to obey the destiny of heaven, I will try my best to do everything, work hard to treat you, work hard to treat things, as for the result is not something I can control, I tried my best, after all, I am not Zhuge Kongming who strategizes.

The wire of the alarm circuit is dropped, and it is recommended to find the reason for soldering.

The general dimensions of the frame level are 200 200mm, and the accuracy is. The scale value of the spirit level is the inclination of the bubble when it moves one square, in seconds or in millimeters per meter, and the scale value is also called the reading accuracy or sensitivity. If the level is placed on the surface of a 1-meter-long flat ruler, and the height of the right end is cushioned at a height of millimeters, the angle of tilt of the flat ruler is 4 seconds, and the movement distance of the bubble is exactly one scale.

Notes on the level.

The level scale value is expressed in terms of angle (seconds) or slope, which means that it is expressed in terms of the angle at which the bubble is offset by one block of working inclination, or by the height at which the working surface is tilted by one block of bubble offset over a length of one meter.

Because the inclination angle of the spirit level is very small, TG, such as TG4 4 radian =, make the working surface of the spirit level close to the measured surface when measuring, and the bubble can be read only after it is stable.

It may be that the line of the alarm circuit has fallen off, and it is OK to weld it, or the rubber ring under the rearrangement is too gray, remove it and wipe it, or the alarm is broken, and replace it with a new one.

1.It may be caused by a damaged glass lens seal that allows environmental dust to enter and block part of the lightIt may be that his trigger power matching sock is faulty, and the voltage of this circuit is not enough, which causes the brightness of the laser light to be reduced.

3.Because the power supply is burned out, the contact is poor, and there is no good lead. In short, in addition to the lack of power, you need to return to repair!

The level doesn't alarm, what's going on?

As soon as the level is turned on, the potato lamp is all lit and does not alarm, it may be that the line of the alarm circuit has fallen, and it is OK to weld it, or the rubber ring under the rearrangement is more ash, remove it, wipe it and it is OK, or the alarm is broken or clear, and change it to a top. 1.Check whether there is a problem with the setting of the lower alarm limit; 2. See if there is a problem with the wiring of the alarm The uneven horizontal plane causes the instrument to exceed the scope of automatic leveling, so the alarm is reminded.

Kiss. There may be several reasons why the level does not light up after it is turned on:1

Low battery or poor battery contact: When the spirit level is turned on, if the battery is low or the battery is poorly contacted, it will cause the spirit level to not start or stop working properly. This situation can be solved by trying to replace the battery or adjust the battery contact position.

2.The power switch is not turned on: Some models of the level are equipped with a power switch, and the power switch needs to be turned on before use, otherwise the level will not start normally.

If the power switch does not turn on, you can try turning on the power switch and restarting the level. 3.Monitor malfunction:

If the level is turned on but the display screen is not lit, it may be that the display hardware is faulty before the noise, and the level needs to be sent for repair to find the repair fault. 4.The program is set up incorrectly:

When using the spirit level, you need to follow the instructions for use correctly, if the program is set incorrectly, the spirit level may not work properly. In this case, you need to check the steps in the user manual about the settings and whether the settings are correct. 5.

Failure of the spirit level itself: If none of the above methods can solve the problem of the spirit level, then it may be that the spirit level itself is faulty and needs to be repaired or replaced. It should be noted that when operating the level, you must carefully read the instruction manual and operate it correctly according to the instructions of the manual to avoid the occurrence of failures caused by incorrect operation.

Hello, it is a pleasure to serve you and give you the following answer: the reason why the level does not light up may be due to low battery power, or poor battery contact. The workaround is:

1.Check the battery level, if it is low, you can replace it with a new one. 2.

Check the battery contact, and if the contact is bad, you can adjust the battery contact with a pointed pin or other gadget. 3.If both of the above methods don't work, you can try cleaning the battery contact of the spirit level to prevent dirt from clogging the battery contact.

Personal tips before dismantling: The contact point of the battery of the spirit level is susceptible to damage from the dirt of the brigade cleaning, and regular cleaning can prolong the life of the level.
