Looks pretty nice inside. As always with recent TTi. Got to love how they put their stuff together with generic parts always. No nasty ASICS with HP part numbers on them 

As for the cal data battery that definitely needs swapping out. Wonder if you can dump and restore the cal data

Edit: service manual covers all calibration options. Nice http://userequip.com/files/specs/1194/1906%20Service%20Manual%20(cct's%20incomplete%20+%20iss%20nos%20different).pdf

Yep, thats why I'm slowly carrying out what we spoke about a couple of years ago, swapping over to as much TTi stuff as I can get they are good and use off the shelf parts so should not be any problem getting parts if required, plus they are incredibly helpful if you need to contact them. Thanks for service manual, I'd already downloaded that and the user manual. My motto generally these days is, if you download the service manual, leave it for someone else to sort out. I think now I have manuals for all of my kit except the Chinese gear.

There is a 3v Lithium 20mm button cell that retains the cal data and as this meter was made in 1997, I suspect that the cell needs replacing, and they stuck it in vertically, right beneath the IEC mains inlet and its boot.

The battery terminals show some nice corrosion which makes me wonder if it is still alive.

We'll find out soon when I strip it down further to check the battery. The test points are also under the main's inlet,

Standard petrol (or gasoline to our cousins on the other side of the pool) has 31.5MJoules of energy per litre, that's 8.7kW/hrs in just one litre. Factors higher than the best battery on the market and we drive around with 40 to 50 litres of it in a glorified bucket every day. If safety didin't bother us up to now, why should it now?

Yes that is true, but Myth Busters did a program about getting a car to blow up like the always do in films when they crash or even get a bullet through the fuel tank and they failed to make it explode or even catch fire.

Just for you Spec, since you were so grievously disappointed. It appears a minigun with tracer incendiary rounds can do the job.

Oh hell, yeah cos I always carry in my pocket a minigun, don't you?

Sorry, that's Saskia's schtick, not mine.

I bet she's right now thinking aboot how to stow it in a backpack for sub-60-second deployment. Or maybe something MOLLE that allows use while walking without someone shoving a wheelbarrow just to carry the ammo.

I am no chemist but I thought that the 'safety' of petroleum mainly came from the issue that the explosive fuel / air ratio is pretty narrow. Too much fuel it just burns, too little fuel - not much. Unlike hydrogen.

What Saskia wrote. (below what I'm quoting) You should be grateful that your landlord does their part on purging legionella. Our geothermal pump makes extra hot water once a week to solve the same problem.

Do you not have tempering valves? Required here in NZ, and then your water is set to heat to >60c, but is then tempered down just before it comes out the tap to 50-55c. That way the water is largely sterilised but still comes out the tap at a safe temperature.

Interesting reading....

Glad to see the result of that. Looks really good. Nice work

I work part time in that area, for hospitals here in Sth Aus, the water is rechlorinated at hospital entry (the gubbermint do a dodgy job) distribution across the hospital is at 60C or above, mixers in patient care areas max at 50C, the mixers need to be dissambled and disinfected 6 monthly, showers run on hot only for 1-2mins every day whether the room is in use or not. Monitoring and records of all of the above. Culture of incoming mains water and cooling water towers - I think monthly.
Another area which is quite tricky is Ice Machines - for immunosuppresed /ICU patients - they are given individual sterile water packs frozen to avoid the 'communal ice bucket/machine ' which is thought to not be good from a microbiol perspective.

Ditto. Awesome finished product.

Neat. Lookit all the women there doing high-precision repetitive work. Also all that expansion and automation... just in time to be obsoleted out of existence.

I think that the Lithium battery in the 1906 might be OK, it is still measuring 3.09V on load (in circuit). I have managed to clean up the battery and the diode D12 so I'm tempted to reassemble the meter and see what ranges need to be calibrated and do those.

EDIT:
Removed PCB and inspected the track side, solder joints also show signs of corrosion, so I have now ordered the replacement battery and will replace while I have the board out, 2 other random solder joints also corroded and yet nothing visible apart some marking on the button cell. All cleaned up and the other joints will be sucked out and resoldered the new battery is installed.

There was a time when I had easily a dozen or more pieces of SONY gear in my home, most of it bought new. I loved and respected the brand for their commitment to quality. Now... unless it's a accident... I think all I have is a HT receiver and a PS3, both bought used because they were just too cheap to pass up. 

I like the part aboot "motivated employees"; I suspect their idea of motivation was a bit more ummm... severe than we westerners would tolerate.

How old did you say that thing probably is...?   

Oh, wait... NM. I see you've come to your senses.

I've got excellent relations with Sony product development and engineering. This comes from frank discussions on various technical subjects. They are good, and do innovative stuff. Once in a while they need a little push, like all vendors.

Yes, the Sony Professional side. Not the consumer goods ;-)

[bd139]

Consumer side is a shit show these days. Total one trick pony. They’re still stuck in pre 2010 thinking culture ie before the rise of the smartphone. The last Sony product I bought was a W880i phone. Typically it was what Sony always did by then: crappy user interface designed to look nice but having major software, electrical and mechanical flaws. Same story across their phone, television, car radio and hifi lines by then.

If I survey across people I know these days, their entire product line is a bit of a dead end. People don’t own hifi stacks any more, half the people I know don’t have cars and most of them seem to watch stuff on their phones and tablets. And none of them own anything Sony.

RIP but they’re dead to me on the consumer side of things. Apple replaced them.

Edit: actually it has got to the point the TV hasn’t been on here for two weeks now. It’s not even plugged in after I rewired everything. It may go. I’ve got a Sony 26EX320 I’m trying to get rid of too which hasn’t been turned on for months.

It's not a trick. It's a SONY!
