How to check an IC?


Hi,
I just made some ICs, and want to make sure there are no shorts, etc.
Can somebody guide me through this?
What I did is turned my R-Shack voltmeter to Ohm x1. and connected probes to the RCA barrel on both ends, and then to both central pins- meter showed about 400 Ohms? in both cases.
Does that mean the IC is OK?
I'm completely illiterate, when it comes to DIY, etc.

If you're on the 1 ohm scale the 400 almost certainly means 400 military ohms, aka .4 ohms.
No worries there if it reads 300 milii ohms with the leads shorted (means your cable is adding only 100 mili = .1 ohms).
You should see low ohm readings from outside ground to outside ground.
You should be OPEN from center pin to outside ground connector.
My spell checker apparently inserted military when I typed mili as in mili ohms.
