Review on Enhance Testing Accuracy with Power Probe 5-Volt Reference Adapter by Charles Quinones

Note that the only function of this adapter is to limit the output voltage to 5V when power is applied (power, not ground. Ground doesn't work with it) . If you don't connect anything to the power supply, and you shouldn't unless you know exactly what the circuit is, you don't need this adapter. Of course you don't want to use 12 when you need 5, but you don't want to use 5 when you need 12 either. This adapter is also said to limit current, but there are no instructions or instructions for it, and there is no current limit on the packaging. If you have a different power supply, e.g. A regulated power supply, for example, and you can adjust the voltage and limit the current might be a better alternative. At the moment I think it was a waste of money because I have a variable power supply and using this adapter is not as easy as I will explain below. This is the reason for my bad rating because I don't want to spend more time learning how to use the tool than the time the tool can save me. So how do you know if it works or not? How do you know that the output has been reduced to 5V? Well, you won't if you don't use the yard. When you apply power the PP is not aware of the connected probe hence the display shows 12V not 5V. Personally before using it seems reasonable to check and make sure you are outputting 5V and not 12V , but I can. I can't think of any way to do this other than with the help of two. It's possible, but quite impractical with just two hands and regular test leads since you have to connect the wires and hold the switch to apply power. The falls help but seem tedious because every time you want to use this you have to search for the yard and the falls. Of course, you could just take their word for it, but I don't, especially since their support team doesn't answer any of my questions about PP. There is one more problem. This adapter will only work if you ground it with an optional PP ground wire. When I first plugged in the cable, the PP went off with a root tone. So when using this adapter turn off the speaker or you will end up with a hammer on your head or the adapter. With proper grounding and power on the adapter and PP, the red LED should be on. If you don't see the red LED on the adapter, there is a problem with the banana plug and/or the grounding plug. Remember this is the LED on the adapter, not the circuit board you want to see! I don't know if my device is bad or not, but just having a banana plug and a cut off grounding plug doesn't mean it will work. I had to fiddle around a bit before I could get an even light. The LED lights up, then I move the board to check and the red LED goes out or flashes. Holding the extra ground wire on the PP case and testing before I touch anything was the only way to get it working stably, but there also seem to be issues with the banana plug so you may need to adjust it as needed. Spring. Before you touch anything with the handpiece, you must first apply power and make sure you have a constant light. Don't just touch the tip of the sensor and apply power. Anyway, another issue is that they only have a small metal tab on the ground adapter and you want to make sure the extra ground wire doesn't break that tab, so use a rubber band or something to secure the wire to the fuselage. pp Also note that when the LED is off on the adapter I read a small voltage at the tip, not 5V or 0V. I don't know how big the problem is. I would recommend that when you buy an adapter, test it out for yourself and decide.
