Red multimeter thermocouple missing ?

[Andy Gelme]

hi All,

Wasn't able to find the red multimeter thermocouple today.

Looked in the box of soldering irons / multimeters ... as well as other
places.

Did it get moved during the working bee last Sunday ?

It was in the original red multimeter transparent plastic blister
package (from memory). Can't find that package either.

Trystan and I were using one this afternoon to test hot end temperatures on
the prussa, is that the one you're looking for?

Hi Rob,

The one we used was for a different multimeter that I found when I couldn't find the one for the red one. I had a little search before I left CCHS today, but still couldn't find it.

Regards,
Trystan

I had a bit of hunting around after you guys left and found it in the storage tub with a lot of the "miscellaneous" electronics stuff, under the bench near the soldering stations etc.
I've put thermocouple currently on the shelf next to the oscilloscope and the (empty) original pack is in the "spare meters/irons" box.

Good that it's been found.

Thanks for that Luke.

I don't know if there is anything special about the one that was briefly
lost, but you can get K-type thermocouples from Jaycar for about $10.
Maybe there should be a couple of spares for when they are briefly
misplaced, or more likely when they are temporarily stuck to things?

They have standard thermocouple plugs, and if that doesn't match the
meter then the meter is at fault. In which case I'd get an adaptor for
it. Standard = good.

Have fun,
Darren

Thanks !

After the big working bee clean-up, it isn't surprising that a few
things are in different places.

Then there is no onus to find the original missing one ... because,
there are more !
After the spares go missing, we are back to square one.

For high usage items, e.g cutters, soldering irons, etc ... having
multiples is good, because they get simultaneous use.

Having spares, because things are put back in the wrong spot ... isn't
the right solution to that particular problem.

We just need to find them ... and put in place a better system for
labeling where things go, e.g the new tool boards.

It is all heading in the right direction.

You assume that when things go missing they will stay missing unless the
subject of an intensive and time-consuming search plus email
conversation. The reality is that things turn up even without all this
effort. Life goes on if you have spares.

We're talking about a $10 item. How frustrating it is to be stuffed up
because the only one was misplaced.. "Sorry, guys, we have to wait
because the only $10 multimeter is in use."

Your position is a little ridiculous. The meter itself is worth several
probes. Our time in discussing this is worth several probes. Getting
another two of them isn't wasteful as they do fall apart with use.

Then maybe you've never worked in a lab where TCs are a high usage item.
I have three right next to me, one of which is temporarily built into a
piece of equipment. But I have only one meter that I trust to read them
accurately.

You couldn't justify gluing the only TC onto the hot-end of a 3D printer
for several days' worth of intermittent testing.. but if you have
spares, why not? Likewise with leaving one inside the SMD reflow oven to
get blackened over time.

Have fun,
Darren

I'll reply ... off-list.

Hi Darren

My understanding is that most (if not all) of the tools have been kindly donated (or on loan) to the space. I my opinion this is an impressive display of community spirit.

If you are saying there needs to be more TC's then there is a wish list on a whiteboard at the space or better still if you are able to donate some TC's, it would fix the need you have identified? 

Regards

Geoff
