BLR121 battery for AVO

[boater sam]

I have had a response from Dekatron. There is a follow up post on UKVRRR February 2015 which I have read and will insert here as follows.


"Hi All,

Files that can be used on a Mac can be found in post #14

This has taken a lot longer than I first anticipated, don't know how many years now, but here it is finally!

The forum software does not seem to understand split zip-files so I had to rename the last two parts with a .zip extension, just rename them to .z01 and .z02 so that you can extract the PDF-file.

Megger has kindly let me publish this OCR-version of the 23rd edition of the AVO Valve Data Manual. It contains the copyright notice they told me to add, which I have written in the PDF-file but I repeat the whole text here below.

----------
AVO Valve Data Manual 23rd edition, OCR version

This is an OCR version of the 23rd edition of the AVO Valve Data Manual. Much effort has been put into making this manual a reality and I hope it will be useful for everyone.

This manual is probably still as full of errors as the original manual but some obvious errors have been corrected, like data showing up in the wrong column or row, but most of the original data is intact. A lot of effort has been put into proof reading the OCR-version by myself but also by my friend Euan MacKenzie. Valve data which had brackets surrounding two or more rows have been converted into separate rows. I will not write more on this as I am sure to invoke Murphy’s Law or Muphry’s Law if I do!

I have centered the tables on each page so that it will be easy to read on a computer, it is still possible to print the VDM but there is no margin adjustment for even and odd pages. I’ve also made every second row grey in the tables so it will be easier to follow them while reading the data.

Megger has kindly let me publish this OCR version of the manual. This manual therefore contains the text “© Copyright Megger Limited” on all pages and also the following copyright notice by Megger:

“© Copyright Megger. Megger retains copyright in all text, still images, moving images and sound recordings ('Marketing Assets') where they were originally created by AVO, Megger or other legacy or associated companies of Megger Limited. Reproduction of the Marketing Assets must be accompanied by the caption "Copyright Megger Limited". These conditions must also be agreed by the third party to whom this copyright information may be passed.

Megger reserves the right to revoke this licence should the Marketing Assets be used for a purpose which at its absolute discretion Megger deems unacceptable.”

You are therefore bound by the usual copyright rules and are not allowed to reprint or sell this manual in any form whatsoever.

This manual in its PDF-file format is fully searchable in all text and data fields except for in the pictures.

So it would seem we have the information but I have yet to read these files.

I'm confused..

[AlanBeckett]

So am I. What have AVO Valve Data Manuals got to do with the VC1?

[pwdrive]

VCM 1? Sam will hopefully know.

[boater sam]

I have no idea! 
It seems Martin (Dekatron ) has an unpublished article re cloning the VC1 for which he is seeking approval from Megger. He is asking them again and if it is confirmed he can make it available.
I simply downloaded the post from UKVRRR assuming there was info in the files but it seems not.

As per what can be found in this thread:

Yes! That's the August 1014 post as I said. More I cannot say. Sorry, its my bed time here.

Interesting ad from wireless world. The SP2 was Ever Ready's basic ZnC so a year's life with allowance for usage and a margin for error is about right!

So from that thread link, 330uA is the quiescent current then.

Having tried a night cycle ride with Blue Seal (the successor to SP2, SP11, etc) in the lamps, i never used them for anything again.

interesting to note there is now a greater proliferation of Lithium coin sizes; likely due in part to technology like aftermarket tyre pressure sensors and the further miniaturisation of car key fob 'bippers'. They are coming down into the size range where they might be able to be stacked into a BLR121 case with a spacer and a spring.

You can fill a BLR121 case with existing 20mm diameter coins. Put coins on side

CR2032 = 20mm wide 3.2mm high
CR2016 = 20mm wide 1.6mm high
etc
