What should a computer repairman avoid wearing when working on a CRT monitor?
Jewelry and Antistatic wrist strap
When should a technician avoid wearing an antistatic wrist strap?
A technician should avoid wearing an antistatic wrist strap when working on equipment that is powered on, as the strap can create a grounding path that might short out components or cause electrical shocks. Additionally, if the technician is working in a highly sensitive environment where static discharge could interfere with the operation of delicate devices, it might be prudent to remove the strap. Lastly, if the technician is in a non-static-sensitive environment, the strap may be unnecessary.
Should you use antistatic electricity when working on a PC cooling system?
There is no such thing as "antistatic electricity". For this reason we can not answer your question.
Which two tools can a PC support technician use when taking apart a computer to best protect computer components against ESD?
A: it is not actually a tool but a ground wire connected to the earth ground which is connected to the chassis The best way to protect your system against ESD is to use a ground bracelet together with a ground mat. Consider a ground bracelet essential equipment when working on a computer.
What tool is used for hardware to stand on to prevent static electricity from buiding up?
You would place hardware on an anti-static mat to prevent static electricity from building up. If you don't have that, you could use other things such as an antistatic wrist strap or even antistatic bags.
Where should the other end of an antistatic wrist strap go?
The other end of an antistatic wrist strap should be connected to a grounded surface, such as a metal part of a computer case or a grounded electrical outlet. This connection helps discharge any static electricity that may build up on your body, protecting sensitive electronic components from potential damage during handling. Ensure that the ground connection is secure and that you are in contact with it while working on electronic devices.
What should be used to clean LCD monitors?
•Antistatic monitor wipes or antistatic cloths should be used for cleaning the monitor
What computer components should you not touch while wearing antistatic wrist strap?
I'm not aware of any component you cannot touch. As long as the power is off and you are grounded properly. You would have to touch any component part in order to replace or upgrade it. When using a Antistatic wrist strap you should always male sure it makes contact your skin properly, if the strap has a crocodile clip at the end make sure it is attached to a suitable grounding point. You can clip it to the PC chassis but make sure the power is off at the wall socket but the plug is left inserted, if you unplug the PC completely there is no grounding. Saying all this grounding yourself is a bit over rated. I rarely use a grounding wrist strap and have never had an incident.
A technician is unpacking a new PCIe video adapter from an antistatic bag to install the card in a desktop computer. Which two measures should the technician use to protect the card and other computer?
The technician should first ensure they are working on a grounded surface, using an antistatic mat or wrist strap to discharge any static electricity before handling the PCIe video adapter. Additionally, they should avoid touching the gold connectors on the card and handle it by the edges to minimize the risk of damage from static discharge or accidental shorting.
How do you use an antistatic wrist band?
There is a strap which you wrap around your wrist and a wire with a clip on the end. Attach the clip to the chassis of the computer to eliminate static electric discharge. Any difference in voltage between the chassis and you will flow through the wire and be neutralized.
Are antistatic wrist wraps necessary?
If you handle component boards / motherboards, etc. only by their edges, or occasionally touch a water pipe or other earthed metal fittings, to dissipate body static, then an antistatic wrist strap is not necessary. I don't wear one, but it depends on how confident you feel - if in doubt, wear one.
Why should you not wear an antistatic wrist strap to repair power supply?
The problem here is that you may encounter high voltages in the power supply. So wearing an antistatic wrist strap may put you at a greater risk of electric shock. Besides, there are few if any sensitive electronic components inside the power supply unit.In addition, make sure the power supply is not connected to any power before servicing it. If you need to go near any large capacitors, you will want to discharge them. In fact that is a good precaution to take any time you remove the circuit board from the power supply unit.
