Hi to all,
I have collected an old (80s) HT 1100A multimeter that seem a clone of a
Fluke of that era.
It mount a classic 7106 A/D converter that drive driectly a LCD display.
When turned off, the display appear in good conditions, no black marks,
brownings or burning signs.
When I turn on the DMM, the display show almost all segments, except
when the display is not 00.0 (that appear like 88.8)
If I measure something that implies display to show fewer segments
(like, i.e., 11.1) the reading is ok without ghost segments.
If I reduce supply from 9V to around 4-5V, the display start to show
00.0 correctly, but with still some light ghost segments.
Replacing the 7106 with another don't eliminate the problem.
Do you think that I can try to solve?
Thanks.

Of course, go ahead. :-)
 
I would check the quality of the internal powersupply in the next step.

If a Soviet-style "and you are still lynching Negroes" is the rebuttal

It isnt. I was talking about legal executions, stupid.

Yep, your other reply was even sillier.

Them too... Given a choice, I'd go with the Indo-Europeans in the
neighborhood.

I consigned old Rod to the bozo bin long ago. Thanks for replying to him

CFLs do not last long when inverted, other than that I would assume it
is OK if made with the usual UL/CSA requirements...
 
Mind you this is from Amazon and there is no regulation there at all,
total Chinese crap (and dangerously so) is my experience in several cases.

I can think of lots of nongrowlight uses for a light that bright, like in a work area, athletics, etc.; just it doesn't seem very "residential" and the other contents of the bag gave clues to the origin.
 
No, it's just that I've heard of CFLs failing catastrophically, but I've never even seen one this big. The basement ceiling fixture is the simple one socket ceramic plate, no globe or shield, so it will mount base up.

Well I use lots of lighting watts now & then in a residential setting, and there's no lack of other people that do too.

So it should really be used base down?
 
It occurs to me that the majority of the light may be emitted sideways, but if I mount it sideways then half the light goes up. (I teach handbell ringing, and the sound comes off the sides of the bell, with very little coming from the end, so I coach my ringers in holding the bell so the sound reaches the audience.)
