In Depth Understanding of Live Cable Identifier
In Depth Understanding of Live Cable Identifier
Everyone should be familiar with the live cable identifier. Xiaobian introduced it in the previous article. It is a very common cable construction and maintenance equipment. At present, there are both instruments for identifying non operating cables and instruments for identifying operating cables. Now we will introduce some knowledge about live cable recognizer. 1、 The transmitter panel of live cable identification instrument is introduced as follows: 1. Signal output port: this port sends the signal to the cable to be tested through direct connection coupling. The instrument can automatically detect the connection mode (direct connection or coupling). When no output line is connected to this port, the screen mode menu displays idle, and no signal is output at this time. 2. Frequency switching: the instrument has four output frequencies: low frequency, intermediate frequency, high frequency and radio frequency. It is suitable for different test systems and has strong anti-interference ability. When this button is pressed, the frequency will be switched between the above frequencies in turn. 3. Power regulation: the instrument adopts constant power output mode, and low, medium and high gears are optional. When this button is pressed, the power will be switched between the above gears. 4. Backlight switch: the instrument has a backlight controllable function. The backlight can be turned off during the day to save power. At night, the backlight can be turned on for test. When this button is pressed, the backlight will be turned on. When it is pressed again, the backlight will be turned off. 5. Power switch: the main switch of the whole instrument. When this button is pressed, the instrument enters the test interface. 6. Liquid crystal display of cable identification instrument: the instrument adopts liquid crystal display for man-machine dialogue. 2、 Precautions for the use of live cable identifier 1. If the operating cable has voltage and there is no load, there is no current flowing on the cable. At this time, the magnetic field cannot be detected. It is considered to be an uncharged cable, which is very easy to misjudge. 2. If the cable is not running, but if this cable is parallel to other running cables, there will be induced current and magnetic field. At this time, the instrument will also have indication, and misjudgment will occur. 3. If there are multiple cables in the cable trench, these multiple cables will generate a magnetic field. At this time, there will be a magnetic field generated by 50Hz current in the whole area. At this time, there will be a magnetic field in the whole area, which makes the discrimination impossible. It is easy to misjudge. 3、 Basic parameters of live cable recognizer insert the red and black wiring plugs of the transmitting caliper a into the two red and black wiring posts corresponding to the transmitting source, and clamp the transmitting caliper a on the identified cable. The arrow on the transmitting caliper a points to the cable terminal. On the identified cable two meters away from the transmitting caliper, clamp the receiving caliper B to the cable, and the arrow on the caliper must point to the cable terminal. Then check the current direction and test connection direction. At the identification point, identify each cable with receiving caliper B. During identification, the arrow on the receiving caliper must always point to the terminal direction of the cable, and the cable shall be clamped one by one. On the identified cable, the current meter pointer of the receiver must be deflected to the right, and the audible and visual alarm prompt shall be given at the same time.
5 Tips on How to Use and Maintain Electric Screwdriver
5 Tips on How to Use and Maintain Electric Screwdriver
An Electric screwdriver is what we generally call power screwdriver. It is widely used in automobile assembly, household appliances, consumer electronics, LED and so on. Power screwdriver works on the basis of ordinary screwdriver driven by power. It can improve working efficiency. Today, I would like to share with you seven tips on using and maintaining electric screwdrivers.Five tips on Maintenance Power ScrewdriverRead the instructions and operate the power screwdriver according to the specificationsThe use of the process should pay attention to the motor size of power screwdriver. Dont operate blindly in case of excess of workload and damage to the power screwdriver. For example, like this screwdriver with torque control its torque range is 3070 kf.cm. It can only tighten objects within 3070 kg but not 80 kg. Because its torque value does not meet the requirements, which will damage the power screwdriver and reduce its life. [caption4. During the using can not be directly adjusted from the lowest torque to the highest torque or from the highest torque to the lowest torque, this is easy to cause clutch and torque thimble off. Thus reducing the service life of electric screwdrivers. Before using the power screwdriver you should tighten the fixing ring (or torque sheath) of. Both ends of the power cable should be symmetrical with the socket hole of the power supply and the electric driver and tighten the nut of the power cable.6, power screwdriver should be kept well, do not allow the corrosive liquid to enter5. Please keep the repair card of the power screwdriverBrushless vs. power screwdriverThe carbon brush life of the electric screwdriver is about 1000 hours. Of course using the original carbon brush, in addition to the power screwdriver to maintain. I suggest buying a brushless electric screwdriver, which is maintenance-free. Brushless power screwdriver will not produce an electric spark, strong anti-interference abilityAlthough the power screwdriver and common screwdrivers are the same, the operation method is simple, but the use of skill is not in place, can cause certain damage to the power screwdriver, so should ensure correct use method and maintenance skill, increase its service life. Brushless power screwdriver will not produce an electric spark, strong anti-interference ability. Brushless motor without carbon brush can reduce noise and wear.
Tips to Clean Stainless Non Contact Voltage Tester
Tips to Clean Stainless Non Contact Voltage Tester
You do not want to use hard abrasives or chemicals that leave a dirty film or stain on the surface. Avoid abrasives and abrasive powders such as steel wool, as these can scratch and damage the finished material. Avoid using abrasive powder or steel wool with bleach or ammonia, which can damage the texture and shine of the stainless steel surface.Some popular cleaning products can damage the surface of stainless steel, and clear water can leave marks and stains if not used properly. Do not use gravelly, dirty or hard water as it can leave stains and brownish stains. Choose a cleaner that is designed for use with stainless steel and start with a gentle cleaner that you can use with a little elbow grease to clean the surface.A soft cloth, moistened with warm water, is sufficient for general cleaning. Use a grease cleaner available at your local hardware store or grocery store and follow the manufacturer's instructions. Apply a non-abrasive cleanser like a soft scrub with a damp sponge and rub off the cleaner.Most filters can be placed in the dishwasher at low heat for a short cycle with a phosphate-free detergent. Of course, like other items in a dishwasher, filters can collect food residues. Filters can be washed by hand in warm water with a phosphate-free detergent such as Dawn.A light paste of baking soda and water acts as a light abrasive to neutralize the remaining acid. Apply the paste to the clean surface with a soft sponge and rub off any haze that might affect the surface or pattern towards the existing surface.Clouds can lead to a stain that can be cleaned so that when removed it is too thin to spread a blurry film. Non-powder coated metal parts, including hardware, are susceptible to corrosion and discoloration. It is recommended to pay special attention to these components during cleaning.There are numerous non-abrasive cleaners and polishes specifically designed for the use of stainless steel. Utilising something like Bon-Ami (r) Cleaner for non-coated or coated surfaces can help minimize corrosion and maintain the appearance of non-coated metal lift components, including hardware. My personal favorite for stainless steel cleaning is the 3M stainless steel cleaner (available on Amazon), but there are several other recommended brands available, including Bar Keeper Friends (available on Amazon ), Cerama Bryte (available on Amazon ), Sprayway (also available on Amazon) and Weiman (available on Amazon ).To make things easier, we have our own brand of water-based stainless steel cleaners that clean gloss, scratches and water stains while retaining the original surface of the stainless steel. If in doubt, test your stainless steel by cleaning the surfaces hidden on the back and sides and then moving the clean stainless steel into visible areas, including the front of the appliance and the tops of the kitchen counters. If you hesitate with stainless steels other than household appliances, there are finishing options such as Classic White, Black, Matte Black and Black Stainless Steel.For cleaning you can use alcohol or other household cleaners such as formula 409, lysol (r) or pine sol (r). Stainless steel is an iron-based alloy that contains chromium that combines with oxygen to form an invisible protective film on the surface, but this film is not stainless. Follow the above procedures to inspect and maintain sealed steel rails and ladders.Non-contact voltage testers are a safe method to ensure that the wires are not touched by current. They light up and make no noise when they come near hot, current-carrying wires, especially those covered with plastic insulation. If you hear continuous chirping or see a series of flashes, this confirms that the tester has detected voltage.On Android, make sure Bluetooth is turned on in your phone's settings and start the tying process on Android. To do this on iOS, your mobile device under the hood must be connected via Bluetooth. If you do not find a device named Zephyr XXX under the hood on iOS during this process, make sure the device is in mating mode.The newest and best commercial cleaners are not the best, but stainless steel cleaners are the safest. Try out some DIY cleaners on your appliances to see for yourself and remember to test the stainless steel cleaner on site before using it.
Bootcamp 487: Moving to a New Pc Part 3
Bootcamp 487: Moving to a New Pc Part 3
Keep abreast of the latest issues in computer technology with Rick MayburyThe absolute quickest and simplest method of transferring data from one PC to another is to 'slave' the old drive. Depending on your level of expertise it should only take around fifteen to twenty minutes and when you next boot up your new PC all of your old files will be accessible, ready to be used or copied to your new hard drive. It really is that easy, however, I wouldn't recommend trying it if you are uncomfortable about poking around inside your PCs or you have any doubts about your DIY skills. If so you should wait for the next two episodes of Boot Camp, which will be looking at totally non-invasive data transfer methods using removable media and cables. It's virtually impossible to get an electric shock from a desktop PC; mains voltages are safely contained inside an earthed metal box and none of the cables emerging from the box carry more than 12 volts. Nevertheless you should unplug both PCs from the mains before you open the lids, we don't want any accidents, do we? Electronic components are remarkably robust but there is a very small chance you could damage something through a static discharge from your body or clothing. Although the risk is very low it doesn't hurt to briefly touch a nearby radiator, metal water pipe or earthed metal appliance, before you open up your PC. If you are really worried you can buy anti-static wrist straps from PC Suppliers and Maplin Electronics for a few poundsStart by opening up your old PC, on most models there will be only one hard drive and it will normally have two cables plugged into the back of it, one for the power supply with four coloured wires (red, two black and yellow). The other one will be a flat 'ribbon' connector that carries the data. Gently remove both plugs, they may be a little stiff, so don't tug on the cables or you may damage them. Tuck the cables out of the way and remove the four mounting screws - two each side. Avoid touching the connectors or the circuit boards on the underside; hold it by the sides and once the screws are out slide the drive out from its 'bay'.Bootcamp ArchiveNext set the drive to 'slave' mode. On most hard drives there will be a printed label showing the positions of the 'jumpers' for Master, Slave and Cable Select (CS). The jumpers are small connectors that bridge sets of pins and they're normally located on the rear of the drive. Your old drive should be in Master mode, so you can use the current positions for orientation and reference. Use a small pair of tweezers or thin long-nosed pliers to change the jumper(s) to the Slave setting. Now you can remove the cover from your new PC and locate a spare hard drive bay. If you are very lucky you will see a spare set of data and power cables nearby, though nowadays most new PCs now use SATA type drives, which use much smaller data cables. It's not a problem, though, and most motherboards have at least one 'legacy' ATA/IDE socket that you can use. If you don't have a spare ribbon cable you can borrow the one from your old PC (see also this week's Top Tip). It's a good idea to do a dry run first and fit the old drive into it's new home. If you have to move cables out of the way do it carefully so as not to loosen any connections. One you are happy with the fitting plug in the data and power cables. Note that both plugs are 'keyed', so they only fit one way around. The plugs should seat fairly easily so do not press too hard and be especially careful not to bend the pins on the data cable socket. If you are using the data cable from your old PC don't forget to connect the other end to the IDE socket on the motherboard..Fit the drive mounting screws and give all of the nearby cables and connectors a final check to make sure you haven't dislodged anything. Refit the case lid and switch on. Windows will boot up as normal and your old drive will be recognised and automatically assigned the next available drive letter. If so you can get on with the job of transferring your data using My Computer or Windows Explorer. If the drive doesn't show up in Explorer then here's a few troubleshooting tips.Switch off, disconnect form the mains, open the lid and double-check the power and data cables. If everything looks okay put the lid back on and boot into the PC's BIOS program. (Refer to the user or motherboard manual for the correct combination of keys to press at start-up). Run the drive setup/configuration utility and check that it has been recognised. On some BIOS there may be a 'switch' to enable the IDE connector. If the drive still isn't found then there is a problem with the data or power connections or the drive is faulty.ANTI STATIC WRIST STRAP Conductive pad, attached to a strap that fits around the user's wrist, attached to a resistor and a wire that clips onto a metal radiator or water pipe, designed to safely dissipate static chargesBIOSBasic Input Output System: diagnostic and configuration program stored in a microchip memory on the PC motherboard that checks the PC hardware before the operating system is loadedCABLE SELECT Special type of data cable used by some PC manufacturers that automatically selects Master or Slave mode SATA drives use a different type of power connector that will not fit ATA/IDE drives, however, most PC power supplies have at least one spare older-style 4-pin power connector as these are still widely used by CD and DVD drives. In the unlikely event a spare connector isn't available you can use a SATA to IDE power adaptor lead. These can be obtained from PC suppliers and typically cost around £2 - £3.Don't forget, there's a full archive of previous Boot Camp Top Tips at www.pctoptips.co.uk

Wire  Trackers
Wire Trackers
The introduction of wire trackerWire trackers are the latest trend in the fishing world. They are a device that is used to detect fish by sound. It emits an electric signal that is picked up by a receiver, giving you both your distance and direction from the fish. These devices come in handy especially when you don't have access to GPS or other methods of determining location.These devices are designed for both professionals and beginners alike and they are easy to use. Wire trackers are not only targeted towards fishermen but also for avid birdwatchers, hunters, hikers, geocachers, boaters and anyone who needs to know their distance from a particular point.Wire trackers have been around since the late 1970s but didn't become popular until about five years ago when they started becoming popular among professional fisherman in Europe andTips for wire trackerIn order to be successful in writing, it is important to understand the essence of wire tracking. With this explained, you will be able to write more professional content and grow your career.Wire tracking is a process where copywriters find out what a company's goals are and then create content that they can share with the company while also promoting their own work.It’s important for copywriters to know what sets them apart from wire trackers so that they can provide value-added services for their clients. This includes providing design services, social media engagement services, and website development services.How to use wire tracker?Wire trackers are not a brand new tool, but they are gaining traction as part of the marketing mix.

Theory of Cable Fault Locator
Theory of Cable Fault Locator
The basic function of cable fault locator is in the power industry and some industries using cables, especially in some complex power systems. It is very difficult to find the fault of underground cable lines. However, in this regard, the continuous emergence of equipment with various functions and simple operation can not only reduce the high cost of fault detection, but also reduce the inevitable long-time power failure when difficult to find (cable fault locator) cable fault, which brings a lot of convenience to troubleshooting. Direct buried cable fault detection in underground direct buried cable and underground residential power distribution (URD) system is a very time-consuming thing, and will cause very inconvenient power failure to users. Some technologies may also damage the cable. For some equipment with high technical requirements, its operation is more complex, and only operators with strict training can use it, which brings a lot of inconvenience to the popularization and application of this kind of technical equipment. Therefore, the selection of appropriate technology depends partly on the knowledge of cable system design understood by the designer of fault detector, and also partly on the professional and technical knowledge of equipment and operators in this regard. With appropriate equipment and professional technology working on site, it is the first step to detect faults quickly and effectively. Hammering (pulse) method many power companies use hammering (pulse) method. This technique is effective in detecting high resistance faults in a simple (cable fault locator) cable system. The hammering method includes using a pulse or impulse voltage to impact the power cut cable. When an effective high voltage pulse strikes the fault area, the fault point flashover and produces a hammering sound that can be heard by the operator along the cable surface. However, detecting cable faults often requires several hammers, and repeated shocks may damage the cable.
