Query: Omron bp meter

The Omron BP meter I bought HEM-711 doesn't give anywhere near the correctBP. If you take the BP at any time the BP is +- 20/30 higher than the BPas measured by registered nurses. You can just see how inaccurate when youtake a BP every 10 minutes without moving, or even every 2 minutes. No correlationin readings at all.
