E2
Omron Blood Pressure Monitor
Severity: MinorWhat it means
E2 means the monitor could not detect your pulse at all.
The cuff is probably too loose, applied incorrectly, or the tube is disconnected.
Affected Models
- Omron M2
- Omron M3
- Omron M6
- Omron M7 Intelli IT
- Omron HEM-7120
- Omron HEM-7156
Common Causes
- Cuff too loose — not sealing around the arm
- Cuff applied over thick clothing
- Air tube disconnected from the monitor
- Cuff placed on the wrong arm (some models are wrist-specific)
- Very cold hands reducing circulation
How to Fix It
-
Check the air tube is fully connected to the monitor port.
Push it in firmly until it stops.
A half-connected tube causes the cuff to not inflate properly. -
Apply the cuff directly on bare skin — not over clothing.
Roll up your sleeve fully.
Even a thin shirt sleeve can block the reading. -
Tighten the cuff so two fingers fit underneath.
If it's any looser, the cuff cannot squeeze your arm enough to detect blood flow.
-
Warm your hands and arm if they feel cold.
Cold reduces blood flow near the surface.
Sit in a warm room for a few minutes. -
Try the other arm.
Some people have stronger readings on one side.
Always note which arm you use and use the same one consistently.
Frequently Asked Questions
I get E2 but I can feel my pulse — why?
Your pulse is real, but the cuff cannot sense it well enough.
The most common reasons are a loose cuff, clothing in the way, or a disconnected tube.
Check all three before assuming the monitor is broken.
