Method
Method	Automatic oscillometric upper-arm measurement; HEM-7196T1-FLE. First retail release date has not been established; the manual's December 2024 revision is not an on-sale date	Automatic oscillometric upper-arm measurement; HEM-7380-E, distinct from older M6 Comfort generations
Accuracy
Accuracy	Maker's pressure accuracy ±3 mmHg and pulse accuracy ±5% of displayed reading; systolic range 60–260 mmHg, diastolic 40–215 mmHg and pulse 40–180 beats/minute	Maker's pressure accuracy ±3 mmHg and pulse accuracy ±5% of displayed reading; systolic range 60–260 mmHg, diastolic 40–215 mmHg and pulse 40–180 beats/minute
Clinical validation
Clinical validation	STRIDE BP approves this exact hardware code as equivalent to Omron BP760N (HEM-7320-Z), with adults, diabetes and pregnancy/preeclampsia listed; equivalent-device approval is distinct from a direct test of this model or validation of its AFib algorithm	STRIDE BP approves HEM-7380-E as equivalent to Omron BP760N (HEM-7320-Z), whose blood-pressure studies cover adults, type 2 diabetes and pregnancy/preeclampsia; equivalent-device approval is distinct from a direct test of this exact monitor and from AFib algorithm validation
Features
Features	Pulse-wave screening for possible AFib, rather than an ECG or diagnosis; irregular heartbeat, body movement and cuff-wrap indicators. The exact manual describes three consecutive readings at 30-second intervals with their average; this conflicts with the UK page's averaging-function No table entry	Screens pulse waves for possible AFib during a routine measurement, rather than recording an ECG or making a diagnosis; irregular heartbeat, body movement and cuff-wrap indicators. TruRead averages three readings with a selectable interval; morning/evening weekly averages
