Turn on the A/C while watching the meter. Make sure temp is set to 5 or more below inside temp. You'll see the amp usage jump up when the fan and compressor 1 start up the come back down. Ours, as I recall is 14-16 amps on one compressor. After a few seconds you should see it jump up again when compressor 2 starts then it will come back down, some. Can't recall what both compressors draw on ours.
Link is to a service manual for the basement air, hopefully the one you have. If you're willing to open the unit you'll see the control board. The lights on the board will tell you what the unit is doing and if there is a problem.
