Yes the aade is good. I had one a place I worked. I now have a slightly=20
different PIC based cap/coil  tester. It's good enough to test coils for=20
high VHF frequency.

if Electrolytic capacitor is leaky it may show up on the multimeter=20
based tester (only does 1nF and larger, the AADE etc is much more=20
accurate and useful to fraction of a pF) as very high value. Also I may=20
connect up bench PSU and see what current there is. Dried out=20
Electrolytic capacitor if not leaky kives very low reading.
