@specmaster: 5KV is pretty impressive. Not sure I’d want to be anywhere near it though with that potential floating around. I’ve had a 2.5KV kick off a tek CRT bias circuit and that wasn’t much fun.

No, I'd treat it with a healthy respect if I was to ever require using it on anything remotely near 1kv. It would be very much hands off approach. I have an Avo 8 which will do 3kv via dedicated terminals and a TMK 700 which does 1.5kv in a similar fashion but that does have thick insulation on leads and probes. But you'd never get me to hold either in case there was a problem.

Did you get leads with it ? If so, are there any V ratings on them ?

Of the first few AVO's I got they some real sus leads that looked like AVO ones but ain't !
I wouldn't use the bloody dodgy things but highly value original AVO leads.
Never had any problems with the originals on a D83 EHT of -2750V.  :phew:
But a 'hands off' approach is wise for these sorts of voltages.

Specmaster:
Yes I got leads with the TMK and the AVO, I haven't got the 1400 yet.

Since the past few days we've been talking vehicles I figured I'd try to tie it into test equipment and TEA.

To wit: An Actron CP9035 OBD-II Code Reader. A form of test equipment. I purchased this unit back in 2001. At that time code readers specifically for the home mechanic were few and expensive. As I recall I paid about $180 USD for this one. And all it does it read and erase DTC's (Diagnostic Trouble Codes) and nothing else. No analysis or trending. But despite that limitation it has paid for itself several times over. But unfortunately it is rapidly becoming obsolete. Starting in about 2005 or so the CAN protocol was becoming more or less the standard. This code reader cannot interface with CAN. But it can work with the older OBD-II protocols. So I can still use it on my 2004 Honda Civic but not on my 2013 Honda CR-V. But I do have a PC based OBD-II program with USB to OBD-II that I can use on that vehicle. That program handles all OBD-II protocols.



In all the years I've had this reader I've never taken it apart. Until now. Here's the main circuit board. I didn't bother to look up the chips but there's at least 1 Seimens chip and several Motorola chips. I couldn't disassemble it further to view the backside because the LM294 on lower left is riveted to the top of the case. Beats me as to why they did that.



So there you have it. Cars, test equipment, TEA.    :-+

I recently got one of the newer ones to use on my Skoda Superb from AliExpress which cost me IIRC £2.50 seems to work really well over WiFi to my phone.

OBD-2 cables FTW. Also got one, a USB jobby and Multi ECU scan. Allows me to kick off the DPF regen before emissions test (thus prolonging the vehicle life and wallet contents) and kill the service indicator every time I don't get it serviced :-DD

med6573's one is a rather nicely engineered bit of kit though. I haven't cracked mine open but it's probably got bugger all in it.
