![]() I just want some cheap, dependable little test lead sets, that again, can do their rated current and not melt, and are a simple, no frills product. Now, what do I want in the smaller, cheaper kit? I don't really want a kit. All I want in the awesome probes, is gold plating, a simple, sharp tipped probe, silicone leads, the ability to do its rated current, and if they're nice and long that would definitely be appreciated. I have a set of these probes and they will remain in my daily carry. Don't get me wrong, when I am doing power supply stuff, they are so damn handy, but every other tiime, they tend to get in the way. Now, Jaycar have such *fairly* awesome leads, but they are not gold plated, and somewhat annoyingly, they have permanent banana plugs on them. Most importantly, I want them to be able to do 10 bloody amps like they are supposed to. I want them to be silocne, and I want them to be gold plated. In addition to my baby's kit, I want awesome basic probes, and awesome alligator clips. I guess I want something this kit would do for all the weird and wonderful jobs I might need to do some day. Basically, I want an awesome test lead kit for my baby - my UNi-T UT181A. ![]() The vast, overwhelming majority of these test lead sets are not branded, so I have no idea what they are like. I assume they would exist in China, just I wouldn't know where to start. I am after two types of multimeter test leads that are both good quality and reasonably priced. OK, enough goofing around, I just had to. I am after two distinct, yet equally important groups: the police who investigate crime, and the district attorneys who prosecute the offenders. If you question the functionality of other sections of the breadboard, repeat these tests in those places.Hi all, I feel like this question may have been done to death, but I'm buggered if I can find it! So, please do accept my sincerest apologies for clogging the forum up if this question has been asked before and I simply missed it because I'm a numpty. The row is isolated from the one below it if the multimeter reads infinite. You test the isolation of one row from another by touching one probe to “A” and the other probe to the “A” hole in the row below. Touch one probe to the “A” and the other probe to “J” in the same row to ensure the row is isolated from adjacent rows. If the multimeter reads nearly zero the row has continuity. You test a row’s continuity by touching one probe to hole labelled “A” and the other to “E”. The multimeter should display infinite resistance, typically represented by the number one followed by a series of dashes, meaning the two bus columns are not electrically connected (i.e. ![]() If want to check that the “+” column is isolated from the “-” column touch one probe to any hole in the “+” column and the other probe to any hole in the “-” column. You test the continuity of the “-” column for that bus the same way: touch one multimeter probe to the top hole and other probe to the bottom hole of the same column. The multimeter will read around zero if the device under test has continuity. You test the continuity of the “+” column for a given bus by touching one of the multimeter probes to the top hole and touching the other probe to the bottom hole in the same column. Find the row number listed on the left side of the breadboard. Next you will locate a row consisting of a group of five holes labelled “A” to “E” or “F” to “J”. ![]() If you have a large breadboard, there may be several buses from which to choose. Set the multimeter to test resistance, typically listed as ohms.Ī bus consists of two columns labelled “+” and “-” that are generally used for ground and power connections. If your multimeter has straight pin-type probes, use alligator clips to connect the jumper wires to the probes. Connect a jumper wire to both multimeter probes. Only use jumpers that fit the breadboard. You will need two jumper wires, which may have been included with your breadboard. You can check both continuity and isolation using a digital multimeter. Because all the holes are connected, the individual columns and rows on the breadboard have continuity and are isolated from the other columns and rows. Consisting of multiple columns and rows connected beneath by metal strips, a breadboard is a plastic grid used for creating and testing electronic circuits designed for use with through-hole components that have connection legs or pins you can insert into the holes of the breadboard.
