Ok #electronics nerds. I must be doing something wrong.

(Edit: Narrator: he was doing something wrong. As usual. Probes plugged into the wrong holes on the multimeter!)

If I put my multimeter on resistance (that’s what I have done, isn’t it?) and I touch the 2 probes together, I expect to see basically 0 resistance. But I see 12.59. Then I touch the probes to the 2 terminals of my thermistor. I get basically the same reading. That makes no sense to me.

I mean, I think the thermistor has gone bad, but I also don’t understand whether I’m doing this right. Is this actually a common failure mode for thermistors or am I doing something dumb with my multimeter?

@paco Are plugs in right sockets for resistance measurement?

Many meters have different sockets for passive and active measurement (voltage/resistance vs current).

[arrjay@tacobelllabs.net]

@paco it should be near 0 for probes together- perhaps a probe is bad?

[paco@infosec.exchange]

@revk I think so?

[revk@toot.me.uk]

@paco Should black always be in COM? Red in Ω

I mean that is confusing, but looks that way.

[paco@infosec.exchange]

@revk Goddammit. I had the probes in the wrong god damn holes! @arrjay

@paco @dashrb This is a lovely example of *** 4 MINUTES *** on the Fediverse.

A random person asks a deeply technical question.

4 minutes later they have working answer.

The fucking fediverse rocks.

OK, I am no linguist, it may be "The fediverse fucking rocks" - someone tells me which.

Glad to be a part of it.

I may go to the pub now...

@paco @revk try black in COM, (bottom right) red in VΩ┥┝ (top right) and then in resistance mode, join the probe leads together. Should read 0 or very close to 0. Lemme know if that's what happens!

@xabean @revk sigh…

@paco
Disregard my post, @revk had the same idea as I did.

Can you post a photo showing where your leads are plugged into the multimeter?

Fucking Fediverse rocks is about the Fediverse fucking.

Fediverse fucking rocks is about the fucking Fediverse.

[paco@infosec.exchange]

@brendan Yep. I am embarrassed. Wrong hole, you idiot. https://infosec.exchange/@paco/116273308690418878

[laguiri@neopaquita.es]

@revk @paco @dashrb it depends if your emphasis is on the excellence of the fediverse (it fucking rocks) or how different it is from a previously mentioned thing (the fucking Fediverse and no other)

[ramsey@phpc.social]

@FritzAdalis @revk @paco @dashrb I read “fucking Fediverse rocks” as being about one who is fucking rocks from the Fediverse.

While “Fediverse fucking rocks” is about the entire Fediverse have sex with rocks.

@paco @revk It's good you got to the bottom of this mystery. We've all made that same mistake before, more than once!

[revk@toot.me.uk]

@brendan @paco Indeed, been there, done that!

Now I need a "got the t-shirt" design for

"wrong hole [multimeter edition]"
