Method
Method	Oscillometric upper-arm measurement during deflation with Gentle+ pressure control. Side switch selects single measurement or AFIB/MAM mode; three measurements with 15-second pauses produce one analysed result. Individual results are not displayed; a fourth measurement is taken if one is questionable. First actual on-sale date unresolved	Automatic oscillometric measurement or auscultatory mode using a separate stethoscope and marker button. Intended for adults at home and in clinical settings. First-sale date unresolved
Accuracy
Accuracy	Current E-V10 July 2025 guide gives systolic 60–255 mmHg, diastolic 40–200 mmHg, pulse 40–199 bpm, static accuracy ±3 mmHg and pulse accuracy ±5%. France page instead gives blood pressure 20–280 mmHg and pulse 40–200 bpm; global support also gives pulse 40–200. These range differences remain explicit. Cuff-pressure display 0–299 mmHg is separate	Pressure 30–260 mmHg; pulse 40–199 bpm. Maker accuracy ±3 mmHg pressure and ±5% pulse
Clinical validation
Clinical validation	STRIDE BP accepts equivalence to BP A100 for adult and diabetes populations, with 22–42 and 32–52 cm cuffs. Headline reflects registry acceptance by equivalence, not a separate exact-model validation trial. Broad maker population and AFib accuracy claims are not treated as exact-model independent studies	STRIDE BP lists X9 through approved equivalence to Rossmax AC1000f, whose adult study used BHS 1993 and was published in 2020; this is not a direct X9 study. Its generic Bluetooth listing conflicts with this non-Bluetooth maker variant
Features
Features	AFib screening only operates in AFIB/MAM mode, not standard single measurements. It is not an ECG recording or diagnosis. Cuff-fit and arm-movement indicators, coloured classification scale, low-battery warning and automatic switch-off after approximately one minute	PARR flags AFib, premature beats, tachycardia above 100 bpm and bradycardia below 55 bpm, including combined findings. Pulse screening, not ECG. Cuff-fit, movement and hypertension indicators

Cuff
Cuff	France maker bundle supplies soft conical M-L 22–42 cm cuff. Guide lists optional S 17–22, M 22–32, L 32–42 and L-XL 32–52 cm sizes and preformed cuffs; these are not all supplied	Supplied latex-free small 16–26 cm, medium 24–36 cm and large 34–46 cm cuffs; overall range requires choosing the appropriate cuff.

Memory
Memory	Automatically stores the last 30 readings with date and time; oldest overwritten when full. Separate M-button recalls previous readings and clears all history. Individual stored readings cannot be cleared, though a newly displayed result can be excluded before storage. History survives battery replacement but clock must be reset. This is the separately named 30-memory model, not the original A150 AFIB S-V9 last-result-only version	Single 90-reading history with date/time for automatic measurements; oldest replaced when full. Auscultatory readings are not included in this stored automatic-mode history
App
App	–	No Bluetooth on this maker variant. Shared-family guide documents an optional specially designed USB cable for PC transfer; Rossmax now says BP Manager software is discontinued and no longer available. Monitor remains independently usable
Power
Power	Four 1.5 V AA alkaline cells; approximately 920 measurements with new batteries, with no separate AFIB/MAM-cycle count stated. Optional Microlife DC 6 V, 600 mA adapter stops battery-current use when connected. NiMH cells supported but require external charging	Four AA alkaline cells, DC 6 V; supplied 6 V mains adaptor rated at least 600 mA. Automatic shutdown after one minute without key operation
Design
Display details
Display details	LCD with date/time, M-memory and ON/OFF buttons, side time control and 1/3 AFIB/MAM switch. IP20. Current guide cover abbreviates the name to BP A150 AFIB; exact official A150-30 download, M/time controls and 30-reading operation establish its applicability	Backlit 99 × 115 mm LCD with mode and pulse-arrhythmia flags; IP21
Size
Size	152 × 92 × 42 mm; 393 g including batteries in current exact guide and maker pages	173 × 115 × 64.5 mm (L × W × H); maker guide lists 410 g without batteries
