/diy/ - Do It Yourself

Close up of the face. Outside of a crack in the glass, there is only normal wear and tear. It doesn't appear to have been dropped and nothing rattles around.

>>1484249
The back with the plates off. Nothing appears loose. How should I proceed? I do have a normal multimeter but I don't know what to check.

>>1484250
For the bargain price of only $964 (adjusted for inflation) you to could purchase one of these fine meters in 1960.

>>1484247
You know with clamp meters, you gotta split the cord. If you clamp it around bot hot and neutral, it will read zero.

>>1484260

>>1484260
>>1484261
For real? Shit son, shows what I know. Let me test that real quick.

>>1484264
They sell these line splitters for like $15. I took a crappy extension cord and stripped the outer jacket so I could seperate the wires and clamp aroound just one and that worked too for just playing around.

But yeah if you clamp around the whole cord, I guess you have current flowing different directions through each wire so it ends up as a net zero. I don’t understand it but that’s how it goes. Good luck,

Hooked it around the power cord to a 6 amp electric motor. Looks like the needle is slightly bent but it does work. But...

>>1484272
I get nothing for voltage. I tried it around the hot, the neutral, and both with the same result.

>>1484274
Does it have somewhere to plug in leads? Clamp meters normally only read the amps with the clamp, you use regular leads to read voltage. At least that’s what I have seen in my 6mos of playing with that stuff.

>>1484278
Indeed it does. I don't have any leads to test it though. Damn, I wish I could find a manual for this thing.

>>1484272
>Looks like the needle is slightly bent
Ignore this. The needle is spot on. It was the crack in the glass that was making it look funny.

>>1484274

Exactly uh...exactly how do you think that reads voltage, anon?

>>1484280
Have you seen my multiple posts saying I can't find a manual for it? I've never used one before.

Thanks to everyone else for the help though.

>>1484282
have you ever heard of google? Did you just walk out of the brazilian rain forest? you are an idiot.

>>1484283
Okay, son. You Google me up a manual for a 'Weston Model 633 Clamp Volt-Ammeter' and I will get exalt you like the internet god that you clearly think you are. Now, don't get it confused with the Weston Model 663, which is easily available but not remotely similar.

>>1484288
I don't need a manual.

just from the pictures I can figure it out.

>>1484288

The issue is that it doesn't matter what kind it is. It works exactly like the rest of them. Clamp measures current (more accurately, measures the magnetic field around a conductor and interprets the current from that), leads measure voltage.

As voltage is a relative measurement, you cannot measure voltage without two points of contact; the point you want to measure and a reference point (usually ground). This is why non-contact voltage detectors can't give you a measurement, and can only tell you whether a conductor is live with more than an approximate, relatively high voltage.

>>1484288
so.... "son" ALL clamp meters are used the same way, you isolate one of the power leads in the clamp and take your reading based on the position of the lever at the bottom, multiplying by that number. Take your time read that slowly as many times as you need.

To read the voltage, move the lever to voltage. attach a wire to the ground (google ground or earth symbol) if you need help. The other lead to the voltage range you want. connect your wires to the AC circuit (try NOT to die). read the meter using the proper range or multiplier.

see! no manual needed.

it works almost exactly the same

>>1484319
To be fair, they don't look anything alike.

>>1484327
I wouldn't need a manual for that either.

>>1484330
We can't all be born knowing how to use stuff without reading manuals or having people teach us. We can't all be like you.

>>1484335
so true

top part of the dial is in volts (red)
screw on the leads and probe the fuck away

If you need a manual to use a volt / amp meter
you have no business fucking around with electricity

>>1484353
Hey, I get to dig up this old DIY meme from 2012. Nice.

So, in your opinion, what should a person first learn if they want to 'fuck around with electricity?'

>>1484366
Google and find out.

>>1484366
The thing is skippy....
you don't want to learn, you just want people to do it for you. people who want to learn use google and youtube and only then when they have questions those sites can't answer do they come to a forum and ask the real questions they need to know.

>>1484391
>>1484389
>>1484386
Yeah, not OP. I'd just like to point out you blowhards sure say a whole lot without actually being helpful. I think the point they were trying to make was a multimeter is probably the best thing to be learning when you are just starting out. Go to another board if your just here to troll people.

>OP asks for help fixing his amp clamp
>turns out it's fine, he just doesn't know how to use it and couldn't read it even if he was doing it right
>Posts a bunch of pissy facebook reaction images because everyone should have assumed he didn't know how voltage works when he was attempting to troubleshoot/fix a semi complicated electronic device
>continues being mad

>>1484425
>complicated electronic device
for a complete fucking retard
Op put this old tool in your rectum

>>1484426
Hey man, I’m the smartest guy on 4chan and even I had to read the owner’s manual on my first multimeter.

>>1484447
how often do you
remove it from your rectum

>>1484460
Whenever I need to use it. It stays up there for safe storage.

I wanna get me a scope one day.

thats a nice find, man
>>1484366
>what should a person first learn if they want to 'fuck around with electricity?
well, for mains Voltage id say
Safety guidelines
local code
The Math behind it
and finally
How does the gear and components you work with function

A meter is useless if you don't know what you want to measure, how you do it, why and especially why you don't get the reading you expected
a lot /diy/ guys generally stay away from mains Voltage, especially if they lack certification or job background
