How to use electronic ruler how to choose electron

Electronic ruler, also known as linear displacement sensor, can accurately measure the size of mechanical displacement. It is widely used in modern industry, such as woodworking machinery, spraying, machine tools and so on. Moreover, it is easy to realize digitization, high precision (the highest resolution can reach nanometer level at present), strong anti-interference ability, no artificial reading error, convenient installation, reliable use and other advantages. Next, Xiaobian will introduce the use method of electronic ruler and how to choose electronic ruler

how to use the electronic ruler

first, install the battery

1, and place it in the direction of the arrow in the battery room

2. The cover is pushed and slid open, and there are positive and negative (+ and -) poles in the battery room.

3. Open the cover

4. Please replace the battery when the battery is low or the rangefinder cannot operate

second, the stabilization of the rangefinder

this instrument is very sensitive to temperature and humidity. Before use, wait 15— 30 minutes until the rangefinder stabilizes to room temperature

III. use of the switch of the rangefinder

to turn on this instrument, press “ Switch/confirm ” Even in dim light, it is easy to display the screen. When the voltage is stable, you can see the ambient temperature at that time. It will automatically turn off if not used for 30 seconds

IV. specific measurement

1. Open the on key and enter the main menu to display gauge data and operation data

2. To save data, please right-click

3. To return to the main menu, press the OK key for 5 seconds to display the main menu

how to select the electronic ruler

1, required accuracy, linearity

2, expected range

3, repeatability/resolution

4, required torque (low)

5, environment, vibration, dust temperature, humidity

6, electrical stroke

7, required speed and expected price and service life

electronic ruler fault diagnosis

1, turn off the power, measure the resistance between I101 and i103, and resistance between 102 and i103, Generally, the resistance between I101 and i103 is the sum of the resistance between I102 and i103 and the resistance between I101 and I102

2. Move the movable end of the electronic ruler and measure the resistance between I101 and I102 or I102 and i103, which should change evenly

3. Observe whether the resistance will change at this time. Theoretically, the resistance between I101 and i103 remains unchanged, and the resistance between I102 and i103 increases with the increase of the position of the active end, and decreases with the decrease

4. If the resistance of I102 and i103 does not change, the electronic ruler is damaged and the internal slide head fails

if the resistance between I102 and i103 decreases and increases with the increase of the position of the movable end, and the computer value changes opposite to the actual position, the wire connection between I102 and i103 is reversed

if the resistance between I101 and i103 changes, the resistance between I102 and i103 does not change, and the resistance between I101 and i103 is greater than that between I102 and i103, the power terminal of the electronic ruler is wrongly connected, and I101 and I102 need to be interchanged

if the resistance of I101 and i103 is found to be infinite, it indicates that the internal resistance wire of the electronic ruler is broken

if the resistance of I101 and i103 is found to be zero, it indicates that the resistance wire inside the electronic ruler is short circuited. At this time, the electronic ruler should be removed, otherwise the a/d module of the controller will be damaged

editor's summary: This is the introduction about the use method of electronic ruler and how to choose electronic ruler. I hope it will be helpful to you. If you want to know more about it, you can pay attention to the information
