Basic Multi-meter Questions


A reminder. Turn off the power to the circuit before doing ohms (resistance; continuity) measurements. Also at least one of the two places (wire, terminal) you touch a probe to should have everything else unhooked from it before you do the ohms test.

Also if your meter has a hold button make sure you don't accidentally push it before testing a circuit knew a guy that got knocked off a ladder because he pushed the hold button and nothing showed when he checked the circuit.

Basic Multi-meter Questions


If you are testing a circuit to make sure it is dead before working on it, a safety check, you should always do a 3 point check.

1- check voltage on a circuit that you know is hot (confirm meter set up right and working)
2- check circuit you will be working on to ensure no voltage
3- check same live circuit you checked in # 1 to ensure meter still working / setup properly

Basic Multi-meter Questions


What is the purpose for these pinchers?


I understand that the pointy end can be used to clip onto a wire,
but I don't see how you connect the probe into the base of this clip.
There's nothing but a little "blade" of contact metal inside the base hole. *
Do you just touch the probe to that little exposed blade?
I was expecting there to be some way to clip the probe onto this extender.
So, what is even the point of this whole thing?
Is the purpose to just serve as an extension probe in case your probe can't reach the wire?
Or is the point the spring loaded clip, in order to secure a hard to reach wire/contact?

Those are 'make your own' wire pinchers....you have to solder a wire onto the end.....

If you pull on that cap, it will come off.

Side note.....I bought my 19 year old son a cheap HF multimeter for Christmas....he now has the official job of testing batteries for everyone....

I believe you can stick the probe of your meter right into that hole on the top, looks like it will only go in one way.

Don't think it's a "solder and make your own"

Press in the large end like a pushbutton so a tiny hook comes out of the small end and you can clip that onto a wire as one of your two test probe locations.

I think this kind of pincher uses a meter probe cable with an end called "banana plug". That is a metal stud a little less than 1/8 inch in diameter with thin springy metal flaps lengthwise against it. That plugs into the large end after you clipped the small end onto the test subject wire. Some meters have sockets on their front panels that take banana plugs in which case you need a cable with banana plugs on both ends.

Does it have a hole in the "blunt" end? If so, it just slides on over the probe tip. Those things are mainly for use when testing electronics -- the little grabbers are good for grabbing component leads.

The probe tip doesn't fit into the butt end hole in any cohesive way.
These things make to sense to me beyond clipping at the pointed end, but having to push the hold the connection at the butt end with the hole.
Honestly, it seems like that way is harder than just holding the probes onto whatever you're trying to measure.

Useless junk.
