U need a thermal camera with this device to see the shorted component getting hot. What you did is, you already knew or suspected the short component. Its not practical to keep spreading alcohol all over the board to find the shorted component.
NO _ it is not essential to have a Thermal Camera. You have Thermal sensitive fingers God gave you for FREE Use those - When you have located the approximate area of heat source - use Alcohol or Butane to determine the exact the component in the area.
I think it is not short detector. It should be called voltage injector or prefixed DC power supply. You can inject voltage with any adjustable DC power supply. It doesn't tell you which component is faulty. It just inject DC power and if the defect component become hot and with help of thermal camera or Alcohol you see the defect component. If it does not become hot, you will not find out which component is the faulty one,.
Sir, what happen when the red probe touch the ground, is it damaged the unit? What if we don't know which one is positive on Motherboard, can we just point it?
If red probe touch the ground the light indicator will goes off meaning it goes to safety mode. If you start at low voltage and do it quick it will not damage the unit. Just observe the current reading.
Got one it didn't last pissing time started playing up after a week on a full charge it lasted 5mins had to keep it plugged in then it had an issue with sending output power to a pcb then it started cutting out.... I bought a I2C Short Killer in the end
sir why did you put the voltage to maximum , wont it harm other components in the circuit , think that a short in a circuit could happen because of ocp , ovp, otp to protect the circuit , so if we inject voltage it will damage the other circuits doesnt it , please explain this
The board that i use in this video is operating at 17vdc. The max voltage of VC04 is only 3.8. If we inject voltage the short component will get hot. You should identify it quickly. Injecting the voltage for longer period of time will damage other components. Some are using flir cam after they inject the voltage to find the components that gets hot but flir cam is expensive so in this video i use alcohol. If you will use the VC04 on mobile phone and laptop boards start from the lowest voltage.
Hi friend...first of all resistor dont cause a short. You cannot use this on resistor. If you put on IC you should identify the pin. Because if you put this on the ground pin then it will read short even there is no short. Start from small voltage to be safe...thanks for your comment.
@@biomedicalelectronicsengin7192 yes sir, if you identified the resistor is good, can i place the prove in the resistor to see if there is a short components near the resistor. thanks sir and have a good day.
1. You have to know what is the voltage rail - The reason is that when there are a lower working voltage you apply a higher voltage to - it will destroy the lower-rated voltage components - such as microprocessors and so on. Make sure to know what any particular volt=yage rail you are working on - and what sensitive devices are on that rail before applying an excessive voltage. The tool is dangerous in the hands of the inexperienced and fools - and will damage boards beyond repair if not careful. Make sure to understand the fault-finding process and voltage rails
Sir posible ba tumunog ang multi meter na shorted kahit, gpu talaga yung may problema? At ano po sir dapat iwasan sa paggamit nito. 19v po kase inaayos kong laptop, shorted smd capacitors sa parteng likod ng Gpu nya
The word is CURRENT not AMPERAGE AMPS is the measurement unit of current You have much to learn to educate yourself/ Better start reading - study more before you attempt any work
@@andrew_koala2974 wtf are u talking about? Amperage is a completely valid & correct term to use in this context. In practical terms, it is the amount of current in amps, which is the answer he was looking for, and also the answer that was provided.
@@andrew_koala2974you need to go back to basic electronics to know exactly what you're talking about. Amps is basically the measurement in current flow in relation to voltage, hence current is measured by Amps.
Wow, so it's a glorified rechargeable power supply that is CV selectable 1V8 thru 3V3? I thought the device was going to detect the milli-ohm and micro-ohm short and display it. This is a total waste of cash then, just use your bench supply to do the same? Or am I missing something here?
A switchmode bench supply is useless - as it will trip when a S/C is detected. However one can use a LINEAR power supply. Clearly, you do not understand Power Supplies
Thanks for this I've learn something new!
Glad it was helpful!
you are really the best , thank you in all your videos always helping
So nice of you
long time to post a video of repair... i will be glad to watch from you something new.

How do i reach you personally? I have a problem with one of these products i bought about a week ago that i need clarification on. please help
i think the probes might be reversed
My short killer shuts off when i join the probes. Any ideas where the problem is?
The unit itself shut off? For safety reason the blue light indicator will off when you join the probes but not the unit itself.
Well done and very interesting. Do you think it is a good device?
Good..but needs extra care. Exposing the board to high current for a long time can damage other components.
@@biomedicalelectronicsengin7192 Should use the lowest voltage?
@@goku445 start with the low voltage. If the short component dont heat up increase the voltage.

sir, is it safe to place the prove of that short detector to any of the components on the board? like, can i place the prove on resistor, an IC, etc?

What readings do you see on the blue tester when it detected the short?

Need paba ng scbematic kung nakakadetect na yan ng short circuit?
No need po.
sir paano po mag set ng ampere nito? sa bench power supply kasi e short mo lang dalawang probe tapos makaka set ka na ng amps
No option for setting up ampere. Once the ampere reading goes high from there you can detertine if there is short
Idol sinugod Nakita kalagpagin at tambaymuna Ako dito
Yes bro...maraming salamat
What is the liquid on the pcb?
Alcohol
Isopropyl Alcohol 99%
@@itworkshop9248 thank you. !!
Nice video. You good

Kung shorted ang gpu mag beep din ang multimeter. Start ka muna sa low voltage. Wag masyadong patagalin baka masira ibang component.
Hello, what amperage does it produce for each voltage?
up to 25a
The word is CURRENT
not AMPERAGE

bench supply shuts off when there is a short. this little short detector don´t shut off
@@johns.185 not when you're injecting voltage into a cap like that. The supply will function just like the short killer no?
