Method
Method	Automatic oscillometric measurement with fuzzy-logic-controlled inflation; designed for adult home use; first on-sale date not established	Oscillometric upper-arm measurement during deflation. Side switch selects a single measurement or MAM mode, which analyses three readings with 15-second pauses into one displayed result. Individual MAM results are not displayed; a fourth measurement is taken if one is questionable. First actual on-sale date unresolved
Accuracy
Accuracy	Maker specification ±3 mmHg pressure and ±5% pulse; pressure range 0–299 mmHg, systolic 60–279 mmHg, diastolic 40–200 mmHg and pulse 40–180 beats/min	Exact April 2020 English/Greek guide gives blood pressure 20–280 mmHg, pulse 40–200 bpm, static accuracy ±3 mmHg and pulse accuracy ±5%. Current global support instead separates systolic 60–255 and diastolic 40–200 mmHg; range difference remains explicit. Cuff-pressure display 0–299 mmHg is separate
Clinical validation
Clinical validation	A&D UK claims ESH 2010 validation; Medaval identifies the UK BIHS recommendation as manufacturer-declared equivalence to the UA-651 and says the equivalence study is unpublished. The US Validate BP listing covers UA-611 under ANSI/AAMI/ISO 81060-2:2018 with different cuff options; this does not establish direct validation of the supplied UK cuff configuration	STRIDE BP lists an exact-model diabetes study using ANSI/AAMI/ISO 2013, published in 2018, and adult acceptance by equivalence to BP A100. Published Beime study abstract reports 85 diabetic participants aged 56–88 and passing both protocol criteria; this does not establish every population in broad maker claims. Registry lists 22–42 and 32–52 cm validated cuffs
Features
Features	Irregular heartbeat indicator, pressure progress bar, WHO classification indicator, stored-reading average and automatic power-off; irregular heartbeat indication is not a specific AFib diagnosis	Pulse Arrhythmia Detection indicates pulse irregularities, not a separate AFib algorithm or ECG. Cuff-fit and arm-movement indicators, coloured classification scale and low-battery warning; automatic switch-off after approximately one minute
Cuff
Cuff fits
Cuff fits	22–32 cm	–
Cuff
Cuff	Supplied latex-free and metal-free SlimFit cuff fits 22–32 cm; optional large cuff fits 31–45 cm, sold separately; UK manual says this model is not designed for a small cuff	Exact guide lists S 17–22, M 22–32, M-L 22–42, L 32–42 and L-XL 32–52 cm cuffs and optional preformed Easy cuffs. Recovered support record does not establish the supplied size, so headline cuff range is omitted. Guide describes removable bladder and hand-washable cuff cover; do not wash bladder
Connections and memory
Users
Users	–	2
Readings stored
Readings stored	30	99 per user (better)
Bluetooth and app
Bluetooth and app	No	No
Memory
Memory	Last 30 blood pressure and pulse measurements, with stored-reading average; no separate user memories listed	User switch selects one of two separate histories, each storing 99 dated readings. First recall shows average of all stored values, followed by individual history. Oldest overwritten when full. All values for selected user can be cleared, but individual stored values cannot; a newly displayed result can be excluded before storage. History survives battery replacement while clock requires resetting
App
App	No Bluetooth; readings can be recorded manually	USB PC link to Microlife Blood Pressure Analyzer+ using Mini-B 5-pin connector. Computer controls device during connection. No Bluetooth or mobile-app transfer. Current software compatibility must be checked separately rather than inferred from old CDs
Power
Power	Four AA 1.5 V batteries; maker claims approximately 700 measurements with LR6 alkaline batteries or 200 with R6P manganese batteries at 180 mmHg and 23°C. UA-611 has no DC socket; the optional adapter in the shared manual applies only to UA-651	Four 1.5 V AA alkaline cells; approximately 920 measurements with new batteries, without a separate MAM-cycle count. Optional Microlife DC 6 V, 600 mA adapter stops battery-current use when connected. NiMH cells supported but require external charging
Design
Display details
Display details	Systolic pressure, diastolic pressure and pulse shown with battery, irregular heartbeat and pressure/classification indicators	LCD with date/time and user indicator, ON/OFF, memory and time buttons, separate user and 1/3 MAM switches. USB and DC adapter sockets. IP20
Size
Size	Approximately 96 × 68 × 130 mm (width × height × depth); approximately 230 g excluding batteries	143 × 85 × 58 mm; 368 g including batteries in exact guide and global support
In the box
In the box	UA-611 monitor, 22–32 cm SlimFit cuff, instruction manual and four AA batteries in the UK pack	Exact guide allows regional packages without cable or download voucher; complete original supplied bundle unresolved. Verified global archived specification/support record serves both resource types. English guide includes Greek regional guarantee wording; this is not a worldwide warranty claim
