If the meter is made in such a way that it will try and carry the load the internal fuse will blow unless it's a UEI meter and it will just explode in your hand (had that happen at 480v).

Testing each side of a blown fuse to ground will give you voltage but doesn't really tell you anything about the fuse.

 

Question back for you

What multi meter is good for 200 amps???????
Voltage check will not blow a meter unless you go over voltage rating of meter.
Back in the days of Simpson meters, before digital meters I modified a meter to put in a reversing switch for the DC. Only problem was it was a 125vdc switch and when testing 250v dc the meter went BOOM. Actually blew the meter case in half but contained the explosion. I'll never forget the look on mt apprentices face, "priceless" when the building shut down.

"when the building shutdown" :laughing:

 

if some moron is checking current instead of voltage on a low impedance meter, the meter will fry (or more likely the leads will burn up if it is a POS)

the OP is now in 1st place for moronic troll threads, congratulations.

Not even close.
Cletis and Frunkslamer must be tied for 1st place, with hundreds of posts

 

Meter won't blow in either situation because he didn't have a valid reason to work live.

 

There's always room for compeditors @ ET.....~C:whistling2:S~

 

There would be no current with a blown fuse ........

 

Is the meter a clamp-on? I don't know of any basic multimeters that can handle 200 amps though a lot of them will do 20 amps.

Assuming the meter is used correctly, measuring voltage across a fuse (blown or not) will not harm the meter.

Measuring current across a blown fuse (direct reading, not clamp-on) will cause the meter to read the current that would be going through the fuse if it were not blown.

If the meter is set to read 20 amps and the load across the blown fuse is 6 amps, then the meter will read 6 amps. If the load is 200 amps.....BOOM!!!

I also know for a fact that using a basic multimeter to read voltage on a 2300 volt transformer will send a guy to the burn ward.........wasn't there but had to repair the aftermath.

Note; a lot of more modern meters have fuses inside the case and the fuse will blow, not the meter. Some meters have fuses on everything but the 10 or 20 amp jacks.

 

I know this question will get some guys

one guy have a multimeter, and this meter is rating for 1000V, 200amps, this guy use this meter to test a fuse in a live switch gear(by the way, the fuse is blow in this case), the voltage of the load is 600V, the load is now 400amps

1. situation A: he set the meter at the voltage testing setting, and test both side of the fuse, will the multimeter blow?

2. situation B: he set the meter at the current testing setting, and test both side of the fuse, will the multimeter blow?

the answer:
1. no
2. yes

I guess some people don't know how a multimeter works:
when checking the voltage, the meter is in parallel
and when checking the current, the meter is in series

 

Where do you find these questions mike? I'm guessing you're picking
through questions from trade school tests/practice sheets.
P&L

 

I know this question will get some guys

I guess some people don't know how a multimeter works:

WTF ?? .. no.. really ... .WTF just happened there ???

Not often do I find myself speechless :blink:

 

We got schooled:no:

 

1. = NO !
On volt setting very little current will flow due to high input impedance.

2. MAYBE !,
Some damage is possable, but it all comes down to how well the meter is designed and how quick the fuse reacts.

It would be so much better and easier to read and understand your questions if they were actually written in English.

 

the answer:
1. no
2. yes

F**k you're stupid!

First off, you don't use a multimeter to test current when you are dealing with anything over 20 amps, and then, usually you are dealing with milli-amps, and usually with DC/ And if you parallel your leads from one end of the fuse to the other, your meter would explode
You use an Amprobe or other such clamp type meter.

you will blow the 200 ua fuse when you test current to ground , which in this case you would have voltage at the line side of the fuse.
BUT, since you stated the fuse was blown, there is no voltage on the load side, so you wouldn't blow the meter.

Checking to see if you have voltage at both ends of the fuse usually indicates the fuse is good ( yes you can get feedback, but thats a different post foryou to invent)

Just exactly what is you level of apprenticeship or are you even in the trade?
The reason I ask, is that most of your questions seem to be what a 1st year or pre-employment would ask. Just enough knowledge to think you know a lot

 

interesting question: will the multimeter blow?

No, but this question/thread does!:whistling2:

 

NUFF SAID !

:whistling2:

 

So Mike, you blew up your meter huh?

 

guys, please relax and chill
I only want to discuss it
so we can learn from each other
I learn a lot from the people in this forum

and that is why we are here

 

:thumbsup:

Mike

I think the issue comes from the nature of some of your questions, now all this depends on your work experience which only you really know how much experience you have. Most members here think or expect a commercial electrician to have a certain level of experience.

KEEP POSTING, you keep us moving

 

im still trying to figure out who doesnt have a meter that goes past 20ampsoh, now i get it! that was the joke

 

Most common meters such as Fluke only have 10 amps max on an in series connection, not like it's a current clamp were are talking about.

 

if it blows a fuse just get a bigger fuse:jester:

 

heres my meter that had blow in the past (some water had penetrate it through the years and contamined the pcb and while reading 600v it blow in my face)
