Went to the local 'Shack today for a few goodies. One of the items was a 10K, 15-turn trim pot. Got home and was reading the package. In their generosity, Radio Shack included the =adjustment screw=. I breathed a sigh of relief, because I'm sure the Trim Pot Adjustment Screw store is closed on Sunday. :-)

They're closed on saturdays, too...
They only sell those screws in packs of 1000, and their 'sample packs' contains only obsolete sizes and types.
(Who uses a T1 external Torx? and the 'One way' types is just plain silly.)

My theory is that to write product descriptions for Radio Shack, you must know nothing about electronics!

I'm sure the adjustment screw mention was put there to distinguish those trim pots from the ones that come pre-programmed and write-protected.

I used to work at a large company which developed business software. And we had a "documentation department"...
There were "writers" in that department who wrote the instruction manuals for our customers. And not a one of them understood computers or software!
These same writers work at newspapers and write Hollywood movies.
(BTW - Parallax documentation is very well written, an exception to the above!)

OK, I'll offer this up as a free project idea for anyone with some spare time. Instead of those pesky numeric display on DVMs now days, how about a graphical Ohm display. It would convert the resistance being measured to a set of colored (or coloured) bands on either a set of RGD LEDs or probably better yet, on a mini color LCD. That way instead of seeing 221.6 ohm, you'd see RED-RED-BROWN, like the world should be!!
Talk about a useful tool and a good use for a micro-controller!! :smile:

Those 10-turn trimpots do have a WORM gear inside. Write Once, Read Mainly ... ?

Interesting...
TTYTT, one of my older Radio shack bench meters has an auxilliary B/W LCD bargraph beneath the digital display and it is quite handy.
Plain old analog multimeters (needle gauges for you young-uns) are still quite useful and have their place.
