Technical characteristics:
- Pressure measurement range - from 20 to 280 mmHg.
- Heart rate measurement range - from 30 to 180 bpm.
- Limits of basic absolute error when measuring pressure - ±3 mmHg.
- Limits of relative error when measuring heart rate - ±5% from measured rate, bpm.
- Voltage of internal power supply which consists of two batteries, type AAA, - from 3,2 V to 2,0 V.
- Current, consumed by device from power supply, do not exceed: 500 mA at air pumping, 1 mA in the mode of indication of current time.
- Battery gauges pull-in voltage - (2,0 ± 0,05) V.
- Quantity of measurements which can be saved in memory - not less then 600.
- Monitoring durability - up to 72 hours.
- Range of operating devices working temperatures - from 10 to 35°С,
- Relative humidity - 30-85 %.
- Dimensions of electronic module - 92x51x24 mm.
- Weight of electronic module with battery do not exceed 0,12 kg.
- Average life time - 7 years.
- In intervals between measurements the device indicates current time and it also has built-in alarm.
Safety of operation is guaranteed by constructive characteristics and functions:
- This is the device with internal power supply and it meets the case of the State Standard 3798-98, type BF;
- The device automatically depressurizes when pressure exceeds 300 mmHg;
- Next measuring is possible only in 30 seconds after previous measuring;
- The device automatically stops measuring if its duration exceeds 120 seconds and depressurizes the cuff;
- The measuring instrument is also equipped with additional patients protectors which do not allow exceeding max pressure in the cuff 300 mm of mercury and max time of measuring 120 seconds. If such protector actuates the cuff depressurizes and the device beeps.
