Test Equipment Anonymous

Probably not a special charger but a reset of the battery mangement system. These systems use a small sensor on the battery connector to montor charge / discharge. If you charge the batttery by other means it upsets the controller causing all sorts of weird issues.

I've not watched the whole thing, but it doesn't set a good example of how to approach a restoration. Just start pulling it apart. :? What about a visual inspection, power up testing and recording of faults. Taking lots of photos is a good idea too. "I know I'm "preaching to the choir"...

Dispite being Irish enough to qualify for a passport if I wan't I haven't had a drink today - yet :) I've a bottle of 12year old Redbreast that will probably be bit lower before the days end. I did go to a Radio Rally today, Grantham. New one for me. It's about 60 miles away. It was pretty wet today...

I Think I need a pay review.
Another project wants me for a couple of days and the project I'm supposed to be on negotiated to have 3 engineers for a week in exchange.....

I was looking at a part on RS today (work so won't go into details) The website did not have much information and the drawing was of a completly different type of part. The datasheet was for the range and did not cover the exact part number. So I started a support "chat" Got a fairly promp...

Was at Tesco this afternoon and picked up a book at the community book exchange. It looked interesting and being free I didn't examine it's teeth :) Title is "Programming Languages History and Fundamentals". It's older than I thought, 1969 and does not include C :o but has several language...

Nice! And the 750VA transformer has to work at 20Hz. That means 3 times the core material compared to a 60Hz one. There are core materials that are better for low frequencies but they tend to be too lossy at the high end for this application. The modern ones are switch mode fith filtering so much sm...

Crows can count up to 2. Evidence comes from observing hides overlooking a field: one person goes into hide, crow don't come to field to eat one person leaves hide, crows come to the field two in, one out, crows don't come to field the second out, crows come to the field three in two out, crows com...

TGGZZZ beat me to it. Looks like a licence copy of the ESI / Tegam Dekapot. As that one has a variable resistor for the lowest deacade it was probably robbed from a bridge. Unusually thes use a R/2R network and double pole switches rather than 10 identical resistors. This give the 12 step "deca...

Possibly because the fashion was for LCD and backlighting a large one evenly was difficult with the LEDs of the time, hence the CCFL backlighting in LCD scope screens of the era. I think I can beat the 177 for late date big LED display though, the Black Star 4503 has big LED digits. In fact, all th...

Don't know why people are getting upset by this one. Yes the buyer is a PITA but many are. I'm more annoyed by the sellers who list as "Used" , which means fully working and then say untested in the description. Or "Used" and "tested working" when the photos show obviou...

I hope and expect it will prove a bona fide sale and all goes well. It's a story I'll follow with interest, as an ultrasonic cleaner is something I've toyed with the idea of buying for a time. I came to the conclusion I'd need two. 6l is great and can handle a lot of things easily, but there are al...

Part two, as we're limited to 10 attachments per post... 20231012_180457.jpg20231012_180412.jpg The display works, if you press it down, so I guess the zebra strip is toast. Worse news is that the readings are wrong. It does change ranges, but gives garbage readings on all of them, that I checked a...

The dodgy display on the 8060A is almost certainly a issue with the zebra strip. There ate two types used and the later one was often retrofitted to early meters. In any case it can almost always be cured by cleaning the strip. LCD contacts and PCB. Use a lint free claoth moistened, not wet, with 99...

Displaytube rapist and TE destroyer in UK trying to sell of kit he hasn't wrecked yet:
https://www.ebay.co.uk/itm/115939571612?
Even then he is cheating by listing the collection at a silly price and then offering individual items for collection...

Umm a Barretter. You don't see a lot of those these days. I do know of one current application. It's in the ignition circuit of some Pratt & Whitney Canada PT6A turboprop engines. These have glow plugs rather then the more common high energy discharge system. Each of the two glowplugs is in seri...

As long as the are display devices and not ultra high speed trigger tubes, no.

Apart from the musical stuff I have or have had most of that kit.
Maybe I should open a Museum. That would save me storage costs......

There is a new rally at Bury St Edmunds at the end of the month. Anyone planning to go?
Buying?
Sellng?

Latest and likely final Wavetek 278 update, I have eliminated the spurious output protection alarm, this was down to the analogue board (referred to as the function generator in the manual) having bad joints on every pin of its Molex power connector *and* having many variable resistors in very much...

Got some new TE, or is it a weapon? RS-HE200-sml.jpg Sort of the EM version of a Thomson/Center Arms Contender. Four "barrels" covering 10kHz to 3 GHz. I now have full set of accessories for my R&S FSH3. It even has the antenna factors for the HE200 pre-programmed in the firmware. I't ...

I did say the Wavetek was working when last used some time ago and that it had a habit of giving an output error message that I never got to go wrong on the bench. Now you've fixed it I'd be happy to give you your £20 back :P Robert. Ah! No need for a refund, it's a thoroughly enjoyable little gene...

Telford is a bit far for me at 125 miles.
I've also just committed the entire TEA fund (teapot?) to a Best Offer on a bit of R&S kit so with luck won't have any funds....

Greetings everyone, I'm a long time reader of this thread in its original place and have decided to type some words here. Southern UK people will likely know me from radio rallies where I've a tendency to buy the odd piece of equipment, with yesterday's rally yielding a "not working" HP 1...

Went to the Milton Keynes radio rally (Hamfest) today. It was (almost) a waste of time. There were not a lot of sellers and virtually no TE. The only just about TE Igot was a handful of Greenpar inter-series coaxial adaptors. The only other thihgs tha made it not a total failure were a couple of odd...
