hi,

i need of help!!

i measured the capacitance of a capacitor 470uf 25V before to discharge it!!
now if i try to do the calibration,it doesn't do it!
if i try to read the capacitance,it's incorrect and it doesn't display the esr!

please help me!!

ESR-micro v 4.0 (снят с производства) / measure of capacito not present in the table

« : 30 Апрель 2012, 18:45:45 »

hi guys,

now has arrived my esr-micro v4.0s   

now i have a capacitor of 1uF 275vac.
on the esr micro i read aesr of 8.4ohm.
this capacitor isn't on the table!
what's the correct value to understant thath the capacitor is ok?
the same for a capacitor of 4.7uF 400v

can you tell me the method for discharge quichly the capacitors?

thx
