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.

When I turn multimeter to Rx 1, and touch probs together- mit shows 300 ohm, when I check a cable (not my DIY cable, but one, I know is fine - I get exact same reading.
BTW, the Ohm scale reads from left to right (it's analog RS multimeter)from infinity to zero

What I meant is, an arrow moves just a little bit from infinity to the right, towards zero.
When i probe is on the barrel and the other on central pin on the other end it doesn't move- "infinite resistance', just like MI8764ag said.

Sebrof,
Thanks.

Almarg,
You are the man- it was low battery, after changing it and adjusting "ohm adjust" knob, I got the following:
IC #1: appr. 0.5-1 ohm b/w ground- ground and the same b/w center pins.
Infinity b/w ground and pin.
IC #2: 0.5-1 ohm b/w grounds, but 3-4 ohm b/w center pins
Infinity b/w ground and pin.
Does it look, like there is a problem with IC #2?

Thanks, I'll try to re-do the RCA plugs. My soldering skills are in the developement stage yet.

BTW, what temperature on the soldering gun do you guys use for sodering RCA plugs?
I have Hakko 936 iron, and use WBT 4% silver solder.
When I used 700 F, as recommended by Chris Venhaus, I found it to be insufficient for this particaular job, and had to use my old RadioShack iron, which, I guess is hotter, and that did the job.

I don't know what size it is, but it's small. Much smaller, than RS one.
