your mileage may vary....but that is my least favorite piece of TE.

bought mine new in about 1993 and it gets very little use.

the little slide on clip ground leads on the probes are dogshit, unreliable, and mostly self destructed in the first couple of years.

had to replace the electroluminescent backlight panel about 10 years ago.  it was not too difficult but the color has never looked right since.

the banana jacks on top are used only for ohms, diode test, and mV up to 3V.  for any voltage test above 3V you have to switch to the bnc jacks and use a probe.  i always forget and it annoys the shit outa' me.

the connector on the power supply is dogshit and practically unobtanium when you have to replace it. and replace it you will.

but it is handy when you need to make isolated/differential measurements.  just slap in some batteries.  then it is for sure isolated and you are good to go.

why do i keep it?  because it is one of the things the evil one wanted out of the divorce in '94.....but i got it.

You'd have a fight on your hands if you tried to take mine away from me!   :-DD

I suspect the concept of dehydration stems from conflating a headache when you've drunk too much or are dehydrated. The Delicious impurities in the dilute alcohol are more likely culprits than the alcohol itself.

Definitely agree with this. Observations from experimentation with remaining hydrated and pissed at the same time:

Bottle of wine -> banging headache.

Several beers -> banging headache.

Bottle of port -> worst headache I have ever had.

Litre of Pepsi Max -> banging headache.

Couple of glasses of absinthe -> banging headache.

Way too much vodka -> no headache.

So the answer is to drink vodka and remain hydrated. To celebrate that discovery I'm going to ignore the findings and crack open another Punk IPA :)

All I can gather is that " KSS " is the name of the manufacturer, whoever that is.

IF anyone knows what KSS does for a living and has a datasheet for this thing, before I add it to my "destined to the trash bin" pile, well that would be nice...

https://www2.jotrin.com/manufacturer/details/KSS

American KSS was bought by AVX in 2004. It's quite likely some sort of filter or oscillator.

That site has data sheets for some other KSS chips, if you register.

Wow.. sounds like you know Jotrin and even have an account there ?! I alwyas thought it was a ghost / fake website, a scam... like the billions of such component sellers that Google floods me with when I search for stuff. So you mean that Jotrin is legit ?! It's a real business, they really sell you components, they don't just run away with your money ?!  :o


--- End quote ---

Never tried them and had no intention of registering. I just found them with a search. The information on KSS seems legit, at least I can't imagine they would make it up from nothing.

My experience of those sorts of places selling obsolete chips, comes from trying to get an out of production CMOS eprom chip for a CRT monitor. There were a few specialist suppliers in the UK with stocks, but they had a minimum order of £50, for a £2 part. The monitor was scrapped. I have no idea whether Jotrin is a bona fide business, but I'd be reluctant to deal with them.

You can forgive the Poms as they've yet not learnt how to properly chill beer !

--- End quote ---

Oh, we've tried. We found that it is impossible to do.

Chilling gnat's piss is easy, however.

Gnat's piss examples include Coors and anything that needs to be advertised by a "muscle man" (Which may or may not also be Coors; nobody cares)

--- End quote ---
Maybe its due to the higher alcohol content of our beers, gnats piss is by default, largely just coloured water  :P :-DD

--- End quote ---

I don't think so. Some gnat's piss has standard alcohol content, and some beer has a low alcoholic content - and is quite pleasant in summer :)


--- Quote ---What ever, consuming quantities of said amber nectar over here in the UK is not to be advised during this heat as the alcohol actually dehydrates you so the experts warn...hang on, isn't that confirming the sentence above has some truth to it  :-// :-DD

--- End quote ---

Beer will dehydrate you less than, say, a G&T. If 10mg of alcohol "dehydrates" you by encouraging urination, then with a beer you will get more water with that 10mg to "rehydrate" you.

--- End quote ---

The whole thing about beer dehydrating you is an old wives' tale. Each gram of alcohol consumed causes a net loss of around 10 ml of water (generally accepted and easy to remember figure). So a pint (568 ml) of 4% abv beer contains 22.7 ml of alcohol, giving 17.9 g of alcohol. This will cause the loss of 180ml of water, but the pint of beer will have supplied about 540 ml of water (with perhaps a small fudge factor for dissolved solids), leaving a net result of at 360 ml of additional hydration.

The G&T case is actually marginal as well: 25 ml shot of 40% gin - ~8gm alcohol - net fluid loss (80 - 15) = 65 ml to be made up with tonic water and ice. So as long as your G&T is 1:2.6 gin and tonic respectively you're not going to suffer dehydration, with any excess tonic over the 2.6 contributing to hydration, but by the time you get any significant hydration from drinking it you're going to be pissed as an admiral.

I don't think this is how it works. AFAIK the water passes through your system quite quickly, while the alcohol takes time to break down. Also I believe the headache associated with hangovers is caused by the buildup of acetaldehyde, which needs more water to help flush it from the system? After a quick read of this I'm not really much the wiser; looks like the answer is "it's complicated".

The fact remains however, that if I had enough to drink that I got wobbly the night before, the morning after I'll have a mouth drier than a sachet of desiccant beads in the Atacama desert.

That has always been my understanding as well. Now I still enjoy a nice cold beer or two, especially on a hot day, but I always wake in the middle of the night with a mouth that feels like I have gob full of blotting paper. I always get a dry mouth in my sleep anyway as have never been able to breathe freely with my mouth closed when I'm asleep, so I have to breathe through my mouth at times, but add any form of alcohol and that makes it far worse.
