i'm thinking with a mask on the end to reduce the aperature, i can check how hot chips are without using the "finger test"

Re: ESR meter upgrades

only the voltage reference really, like last time - i think you have spares of the lm4040

beware of the case, if it's the acrylic ones they crack.

ask here:

it looks o.k. but a colour display would have been better.

Yes true no colour screen on these, so a ay-at it is then as aliexpress has a sale on and these can come with a case etc, too save me reading loads of pages in the eevblog thread lol, do you know what if any parts are recommend to swop out? before i update the firmware, i will also keep too a 9v battery as fits in case nice.

Re: ESR meter upgrades

@STJ,
Did you investigate the AY-AT firmware further? (See message 928)

Re: ESR meter upgrades

I have uploaded the firmware from one on eevblog.
Yes it has a menu where you can select the basic modes of operation, including only ESR.
If anything's missing just compile your own

Re: ESR meter upgrades

Thanks for the recommendation. I like that it has a case and probe ports. But I'm wondering if it has menu access like the GM325. Does this allow for manual settings for component testing? I mean can it be set specifically for testing ESR, without the firware trying to guess what the component type is? Also, I have read that it does have a flashable firmware. Can you confirm this?

Re: ESR meter upgrades

Hopfully this isn't too off topic. Is there a concensus on a good prebuilt variant of these component testers? I'm particularly interested in using one for manual ESR testing.

Re: ESR meter upgrades

no, i need to get back to that.

@STJ,
Did you get any further investigating the AY-AT firmware?

Re: ESR meter upgrades

Re: ESR meter upgrades

Hi STJ, I like your avatar, I've been in facebook jail 5 times already. Can you please compile another lipo version of the AY-AT like you did for me before on post 855 but with the modifications that fill up the display? the 3.2 volt cutoff version worked best, the 3.6 cutoff version gave me a low battery warning when the lipo was at 3.9. BTW the rechargeable mod I made in post 873 works great.

Re: ESR meter upgrades

the russian one didnt have these problems??

I think the problems with the menu side were the same, having said that I can not read Russian but the menu did not seem to change when a selected item was pressed. Your first T4 worked perfectly as did the second T4 as far as diagnosis were required the second one had smaller fonts and very fast, the problem seems to be selection from the menu pressing button.

Re: ESR meter upgrades

some quick builds:
GM328 and AY-AT for 16MHz
both using compact font with more menu lines.

and a T4(strip-grid) 16MHz testbuild for TEDDIBEAR.

Hi stj
thank you for your update I am afraid I am still unable to select from menu
here are the results. + when a test is made it stays on the screen for a split second too quick to read

Re: ESR meter upgrades

fuck, i set that for 16lines.
must be more shit hidden away.
