latest is 1.12k SVN r684
and it does NOT support multi-coloured display output.
so you should try to dump the atmel in that unit.
fixed.

if it's your first - you wont really know any better,
- Is the slow display a real issue?
if not then it will piss you off pretty fast.
it may be fixed by upgrading the clock from 8 to 16MHz with a new crystal - i will report on that when i get some more crystals.yes, at the moment you cant enable the crystal / resonator test.
- Are you missing features due to Memory limitation?
(that test only works if you upgrade the crystal to 16MHz anyway)software updates come from people like me and other forum members.
- Delay in software updates or none?

you can use both versions on any modern hardware.
modern as in using a cpu with atleast 32k flash.
no old ATMEGA8 / 168 hardware
I have a question about the VCC measured during self-adjustment of the m version. I measured it as 5.024V with a nicely adjusted DMM and set that in the config file. After the adjustment procedure, it gets set to 5.038V. Where should I look to correct this (i.e, I want the self-adjustment to measure correctly rather than just setting this manually)?
I need a cheap ESR tester to test a load of capacitors on a faulty power supply board. This looks like a good option.
There are loads of these chinese units out there. Not bothered about programming (maybe later, just dont have the time at present).
This unit seems okay as its got banana plugs and the zif board you can plug in.
Any comments, or any other units I should be looking at?

If you have enabled the external 2.5V reference in config.h, then the value set via UREF_VCC in config.h is adjusted accordingly to the external reference. In this case, measure also the voltage of the 2.5V reference and change UREF_25 in config.h too. Or disable the external reference to prevent the automatic adjustment of UREF_VCC. You might also need to tweak the values a little bit to reach your desired voltage, because the ATmega328 has a resolution of only 4.88mV with Vcc (5V) as reference. Another setting to play with is ADC_SAMPLES. More samples will improve the measurement, but slow it down at the same time.
The only thing i've found is (compiled) firmware on this site:

...but this 8MHz firmware is in the Russian language, don't misunderstand me, i don't have anything against Russian, but i can't simple read it and don't understand it either.
