A/C Troubleshooting

So I have a 97 900SET and the A/C compressor never engages. I put a set of guages on for a pressure readings and at 80degrees ambient temp I get:
10 psi Low side
10 psi High side
with the engine off, on, and on with A/C on high.
I haven't tried charging her yet. From what I have read on this board it sounds like the pressure is way too low so the pressure sensor is stopping the compressor from kicking in.
Should I just tried and charge it with a can of R134 and see if the pressure climbs and allows the compressor to kick on?
I don't know the history of the car so I am not sure what has been done in the past. A/C hasn't worked since I have had her (2 months).
Thanks.
