I'm building out a 200 - 600 watt off grid solar system on my KZitem Vanlife van. Re learning my 12th grade physics, amps x volts = watts, circuts, parallel/series, components, etc. I remember breifly soldering wires when I was 11. But, never even owned a multimeter. I just bought a cheap one and would have blown a fuse. Now I wan't to buy a breadboard, resistors, and LED's and geek out with all of this stuff, and test everything in sight using E=IR formulas like I'm a German kid from Frankfurt. My power windows went down in the van, so I need to isolate that problem, and dive into it all to get hands on & figure it out. Look foward to it! Very, very well explained here. Subscribed.

The first thing you should always do before taking a measurement with a meter is to verify it is working properly. For low voltage situations, simply measure a battery to confirm the meter sees the voltage. For a house wiring system, go to a known working socket and measure the voltage. The purpose of this is to prevent a false negative measurement. Imagine that a test lead has a broken wire, or the internal fuse is blown on the meter. You could check a wall outlet to see if it is safe to work on and get a zero voltage measurement even if the outlet has voltage on it. This is a very dangerous situation. Even a low voltage situation is troublesome because you will waste time if you have a broken lead.

Very interesting. Thank you. I have a cheap-o multimeter that reads only to something like 400 ma. I'm trying to sort out the wiring on a drill press with a good 10 A motor and a new switch. Unfortunately, the previous owner rewired with all red wires. When I plug in the machine I trip the 20A circuit breaker. My guess is that the machine's main switch or the work light is improperly hooked up. Can I jump a 9V battery to the plug and learn what's going on that way without frying the low-end Harbor Freight meter?
@Science.Buddies
2 жыл бұрын
Hi - one way to avoid frying the meter is to put a large resistor in series with one of the leads. For example if you put a 1 kilo-ohm resistor in series with the load that is powered by a 9V battery, then at most even if the load is short circuited you would get i = V / R = 9V / 1kOhm = 0.009A or 9mA. The drill press won't run with current that low but it would allow you to test wires if your meter does not have a continuity check feature.

When I test this in the wall outlet, it just flashes or goes blank instead of showing 120V. Any idea why? I believe I have the same multimeter but it is yellow. Also, when I measure a AA battery at 2000, it says 1757 volts, and at 200 it says 177 volts and at 20 it says 19 volts. None of these values match the ones he gives and I am testing the same Energizer AA battery. Haha. Also, the battery is rated as 1.5V, so none of these numbers make sense. Is my multimeter messed up? I dont think I can trust it. The fuse filament looks fine and yes I used ac volts when I measured the wall :)
@Science.Buddies
4 жыл бұрын
Hi - separate issues - when you measure the AA battery with the DC volts setting, the multimeter is probably displaying the reading in *millivolts*, not volts. One volt = 1,000 millivolts. A fresh AA battery will provide a little over 1.5 volts, or 1,500 millivolts - so your reading when set to 2000 makes sense. The other readings depend on what your multimeter does with the decimal place for each setting, which will vary from multimeter to multimeter. As for the wall outlet, since our content is for kids we generally recommend that students don't measure wall outlets since they can be dangerous. If you need help measuring AC voltage you might have more luck in an electronics forum or asking an electrician. Thanks!

Fresh AA batteries will usually ready about 1.6V. Anything over 1.7 does seem high. I have noticed that very cheap multimeters will give slightly different readings on the different settings. Unfortunately there are so many multimeters out there that we can't really provide specific advice for the different models. If there's any way you can get access to another multimeter somewhere (borrowing one at school, from a local makerspace, etc) then you could measure the same batteries with that, and see whether your multimeter is giving incorrect readings.

In general, you need to be careful when turning the dial and connected to a circuit. For example, it is OK to switch between different voltage measurement ranges when connected to power, but if you accidentally switch to one of the current measurement settings, you can blow the fuse in the multimeter depending on what you're connected to. Hope that helps!

I'm kind of freaked out. I tried all sorts of different things under the resistance dial. What should I do now? 🥴 My solenoid reading should be between 500-900 ohms.
