Method
Method	Oscillometric upper-arm measurement during deflation with Gentle+ control. Single or AFIB/MAM triple mode selected by side switch; three measurements separated by 15 seconds produce one analysed result. Questionable measurement triggers a fourth; individual triple-mode results are not displayed. Actual first retail sale unresolved	Automatic oscillometric upper-arm measurement during deflation with semiconductor pressure sensor. First-sale date unresolved
Accuracy
Accuracy	Current E-V11 MDR guide gives systolic 60–255 mmHg, diastolic 40–200 mmHg and pulse 40–199 bpm; global support lists pulse 40–200. Older S-V10 guide and French maker page give blood pressure 20–280 mmHg and pulse 40–200. Static accuracy ±3 mmHg and pulse accuracy ±5%; 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 exact A6 BT for adult and diabetic home use by equivalence to BP A100, with referenced 2009, 2018 and 2021 studies. This does not establish separate published A6 BT trials for every special population mentioned by the maker. Blood-pressure validation and AFib screening are separate claims	STRIDE BP lists Z5 as equivalent to the validated Rossmax CF175, rather than directly studied. Medaval says the equivalence evidence is unpublished and cannot be checked against MDR requirements; headline validation omitted
Features
Features	AFib pulse-irregularity screening active only in AFIB/MAM triple mode, not single measurement. Does not record an ECG or provide an ECG-confirmed diagnosis. Cuff-fit and arm-movement indications, LED pressure classification scale, low-battery warning, automatic switch-off and lock switch to prevent accidental activation	PARR flags AFib, premature contractions and combined findings; not an ECG. Cuff-fit, movement and hypertension indicators; non-storing guest mode. Generic tachycardia/bradycardia marketing does not establish dedicated detection icons
Cuff

Cuff fits	22–42 cm	24–40 cm
Cuff
Cuff	Current MDR guide supplies Microlife Soft Cuff M-L 22–42 cm. Optional soft cuffs S 17–22, M 22–32, L 32–42 and L-XL 32–52 cm are not all supplied. STRIDE lists validated 22–42 and 32–52 cm sizes	Latex-free Universal Cone Cuff for 24–40 cm arms

Bluetooth and app
Bluetooth and app	Yes	Yes
Memory
Memory	One history of the last 99 dated readings, with no user selector in exact controls. First recall shows average of all stored values; older guide calls it 28A without defining a 28-day interval. Forward/backward buttons navigate history, oldest overwritten when full. Complete history can be cleared, individual saved values cannot; newly displayed reading can be excluded. Readings survive battery replacement while clock requires reset. Isolated manual wording per user does not establish two separate histories	Two 60-reading histories with date/time; latest-three average and seven-day morning/nighttime averages. Morning uses 04:00–11:59 and nighttime 18:00–02:00. Oldest reading replaced when full; guest readings not stored
App
App	Bluetooth 4.0 synchronisation with Microlife Connected Health+; connection active after measurement and can be started with forward button in standby. USB transfer to Blood Pressure Analyzer+ PC software. Both manuals specify Mini-B five-pin connector in PC-link section, while current package list calls its cable Micro USB; connector wording conflict retained. French page keeps older app OS requirements; current supported phone versions should be checked with the app	Bluetooth low energy transfers new and saved readings to the phone app after pairing. USB cable is specified for power only; a generic BP Manager diagram does not establish PC data transfer
Power
Power	Four 1.5 V AAA alkaline cells; approximately 400 measurements with new batteries, not a separate triple-cycle count. Optional Microlife DC 6 V, 600 mA adapter; French bundle list includes it despite technical table calling it optional. NiMH cells supported with external charging, not charged in monitor	Built-in non-detachable DC 3.7 V lithium-ion battery; Type-C input 5 V, 1 A. Maker claims approximately 600 measurements per full charge, depending on battery and storage condition; charging takes up to three hours depending on discharge. Green charging light goes out when full. Battery replacement by authorised service centre; automatic shutdown after one minute
Design
Display details
Display details	LCD with date/time and AFIB/MAM indicators; START/STOP, memory, time and forward/backward controls. Separate lock and single/triple switches, cuff, USB and DC sockets. IP20	69 × 64.4 mm LCD; IP21
Size
Size	Current E-V11 MDR guide, French product and global support agree on 160 × 80 × 32 mm and 354 g including batteries. Older exact S-V10 guide incorrectly gives 150 × 100 × 50 mm and 580 g; conflict retained rather than transferring that table	120 × 80 × 57 mm (L × W × H); 276 g including battery, excluding cuff
In the box
In the box	Current MDR guide lists soft M-L cuff, cuff holder, cuff-size marker, USB cable, storage bag, diary, instructions and four AAA cells, with adapter optional. French regional list includes adapter; regional bundle differences remain qualified	Universal Cone Cuff, USB cable, instruction manual and zipper bag; mains adaptor optional
