For anyone who may find this info useful in the future remove and check R1. It should be 1ohm. Mine was over 30ohms. Replacing it temporarily with a jumper brought it back to life. Waiting on some 1ohm resistors to repair it properly.
It's possible. It is true that usually the resistor burns completely, but this may happen. It works there as a fuse - if you connect charged capacitor to it, the input transil shorts it but you get huge currents flowing through the 0,25W (in later versions 0,5W) resistor.
Less jewellery, more gold into electrotech industry! Half of the computer problems is caused by bad contacts
I have seen the resistor failed mode like that many time from many repair works. If you work on many many many many kind of electronics for so many many many many years, you will see lots of failure modes of the components.

I am not going to debate over this, even if I do not consider possible such event at the fraction of a second, to be capable to do such damage.
From the other hand if the true reason of such a damage in one ESR meter is due bad handling or irresponsible use, I am not surprised.
Before some time, some one got a fresh cheap multimeter and his first measurement was an electric fence.
The meter got toasted and he learned something useful too.
I think that several mF at several volts carry quite a power
One 1000uF at 16V does not looks a nuclear reactor to me, but the boys who are planing to play with super capacitors, they must be 100 times more careful with them.
Mine died too. I barely used it a couple of times? I don't remember, that I have used it improperly.
I have replaced the batteries, but didn't change anything.
I should check that 1.0 Ohm resistor?
I have the 4.0 version and I have purchased it in April 2012.
I have measured it and it's fine.
I have started measuring other components and while I was measuring one of the transistors, I have just heard the startup beep.
Not sure what happened, but it's working now.
