Mike already has a mod for his meter to include auto-discharge, but I can totally understand your position Béla
Caps (electrolytic one's) Usually have a a high tolerance (that is variation in stated value). Usually it's 20%.
Also usually manufacturers succeed in making the caps have a HIGHER value than specced, because that is often better than a value below specced.
This value is within -10%, if the cap is specced at 20% it is OK still. ESR is fine.
About the Russian meter, that's just one guy earning some cash with his hobby. Peak is more of a company.
Both have advantages and disadvantages. The auto-discharge is sure an advantage, but I didn't like the crocs, and especially the DIP socket to test new caps is ideal on the Russian one. Not to mention....it's about half as cheap...
