The only way to check for a drain is put a meter in current measuring mode, disconnect the positive lead and connect the meter to the red lead and battery positive. You will be putting the meter in series with the battery not parallel like when measuring voltage.
This will tell you how much is current is being drawn when the ignition is switched of and alarm switched on.
The only items drawing current should be the Clock and the alarm. The current should be below 10milliamps and probably more like 5milliamps or less.
If more, disconnect the fuses one by one to see which circuit is drawing the current.
Start with the alarm fuse.
Do not switch on the ignition when the meter is connected like this. Current draw could be to high and at best the meter fuse will blow and at worst cheaper meters will be consigned to the scrap heap.
