How do I use a multimeter to check atty's?

[justincase]

Could someone please explain to me how to do this?
I was told in another thread to set my meter to the infinity symbol and put on lead on one end of the atty and the other lead onto the bridge, however, that doesn't seem to do anything for me.
I don't know anything about a multi meter and I don't know if they are pretty much all the same, but if not, here is the one I am using.

I appreciate any help.

i think you can find a visual guide to what you do at the above link


you put the positive on the hole of the center post and the negative not on the bridge but on the base of the center pole right next to the threading

and i would say turn that dial to the right to were it has the ohm sign

JUSTIN,
the meter you show has a kilo-ohm scale. See if you can find zero on the scale, then 1 X1000 ohms on the scale and then 100 ohms (probably the first tick mark), then find 2 ohms on the scale.

You may only be able to tell if the atty is not OPEN but not whether it is 2 ohms or 2.8 ohms, or 39 ohms.
I would't worry about adjusting anything with that meter. You can determine continuity.

and tybin is sort of correct. The atty has two connection at the battery end. The center post and the shell. One meter lead to each will show the ohms just like the battery sees it.


and your multimeter will work on ohms with a good battery. All the other ranges don't need the battery.

on the thread end of the attie, you will notice the center part where the hole is, is separated from the thread part by a little rubber seal. You will be checking the continuity between those two parts which will be your ohms

Edit Rocketman is right, you may not be able to dial in tighly on what your ohm reading is, but you can check to see if you have continuity. If the needle doesn't move when the probes are attached it probably means the coils blown and therefore you lose that continuity. Just like a light bulb

I didn't find anything on that site. Must not be looking in the right spot or something. Seemed like an e-cig store to me.
I put the mm on the oHm setting and the "needle" moves off the chart (goes all the way to the right). There is a little dial on the left hand side of the meter, which I turned in the opposite direction it was set in, and tried again and it still read all the way off the chart.
What does that mean?

Is there a small crossed "screw" on the front right at the pivot point of the meter needle? That is the Zero set for the meter movement (left side of scale). (no meter leads needed)

Short the meter leads, and adjust the swing with the thumbwheel for the ohms zero (right side).


(we keep posting the same thing a few minutes apart, what time zone are you in? )

 

[squirrel64]

short the metal probes = hold the 2 probes together and adjust the reading to 0 if you have an adjustment.

 

[justincase]

Well, I don't know what I'm doing.
I touched the leads to each other and the needle swings all the way to the right. I moved the little dial on the left side of meter until the needle was on the zero, on the right side of scale with leads touching.
tried testing a few atty's that were laying around, the needle moved to O.
Took a brand new atty out of the box, never been opened and tested it, dial went straight to zero.
Am I doing something wrong?

 

[Rocketman]

NO you are doing it right. Your meter scale is calibrated in kilo-ohms. The 1 on the scale is 1000 ohms. An atty will read about one RCH more than zero.
(if you don't know, don't ask )

I'm buying a digital mm. That's all I can say!
This is something that was purchased on the fly just to check the probes or whatever on a water heater. It has served it's purpose. I need a new one to serve a new purpose.
Thanks for helping the helpless.

Analog meters still have their purpose. You just demonstrated the capability to test for continuity.
