NOYAFA Electronic specializing in testing instruments and cable testers for 16 years
Everyone should be unfamiliar with the charging cable identifier, Xiaobian introduced in the previous article, which is a very common cable construction and maintenance equipment. Currently, there are both instruments for identifying non-running cables, there are also instruments for identifying running cables. Everyone should be unfamiliar with the charging cable identifier, Xiaobian introduced in the previous article, which is a very common cable construction and maintenance equipment.
Currently, there are both instruments for identifying non-running cables, there are also instruments for identifying running cables. Let us introduce some knowledge about charging cable recognizers. First, the charging cable identifier transmitter panel describes the following: 1. Signal output port: This port will be sent to the tested cable by direct connection, and this instrument can automatically detect the connection mode (directly or coupled), when this When any output line is received on the port, the screen mode menu is displayed as“idle”No signal is not output at this time.
2, frequency switch: This instrument has four output frequencies of low frequency, intermediate frequency, high frequency, and radiofrequency, suitable for different test systems, strong anti-interference capabilities, when this button is pressed, the frequency is turned between the above frequencies. . 3, power adjustment: This instrument uses constant power output mode, low-grade, mid-range, and high-end three gear options. When this button is pressed, the power is switched between the above gear. 4, backlight switch: This instrument has a backlight controllable function, and the backlight can be turned off during the day, and the backlight can be opened in the evening. When this button is pressed, the backlight is turned on again, and the backlight is turned off.
5, power switch: The total switch of the entire instrument, when this button is pressed, the instrument enters the test interface. 6. Cable identifier Liquid Crystal Display: This instrument is interrupted when using liquid crystal display. Second, the charging cable recognizer uses the precautions 1. If there is a voltage of the cable, no electricity is not loaded, the cable is not detected, and the magnetic field is not detected, it is to be a non-electric cable, which is very easy to generate misjudgment.
2, if the cable is not running, this cable will have induction current generation if there is parallel with other running cables, and the induction current will also have a magnetic field. At this time, the instrument will also indicate that it will Generate miscrosis. 3, if there will be multiple cables in the cable, there will be magnetic fields, and the entire area will have a magnetic field generated by 50 Hz current, and there will be magnetic fields throughout the area, so that the discrimination cannot be done. It is easy to generate miscrosis.
Third, the basic parameters of the charging cable identifier will emit the red and black two wiring plugs of the emission caliper, on the two red and black line columns corresponding to the launch source, and the emission calipers A card is identified on the cable. The arrows on the transmit card pliers A points to the cable terminal. On the identified cable other than the emitter two meters, the receiving calipers B are attached to the cable, and the arrows on their caliper must point to the cable terminal.
Then check the direction of current and test connection. In the identification point, each cable is identified with the receiving calipers B. At the time of identification, be sure to always point the arrow on the receiving calipers to the terminal direction of the cable, and tape by cable.
On the recognized cable, the receiver current table head pointer must be deflected to the right while the sound alarm prompt. The above is about the related knowledge of charging cable recognizers, hoping to bring some help to people need. If you have problems with cable testing equipment, you can continue to pay attention to Xiaobian, more exciting content, let us continue! .
