Style:
The blood pressure monitor is intended for the wrist. I particularly like the small size and low weight. This is important if one wants to have to travel the blood pressure monitor with it. All corners are rounded and when you turn, there is a pleasant blue backlight which makes the numbers easy to read. The buttons can be easily operated. Overall, the unit makes a high impression. The manual is available in printed form and in German (among other languages) language before. Here the functions and handling are explained in detail and in good quality.
Commissioning
Commissioning is very simple. It comes with two AAA batteries. There is a flap to insert the batteries on the lower side. The correct polarity is characterized by ever a plus and minus sign. After inserting the batteries can be set with the SET and MEM key the correct time, date, 12/24 hour display, and the unit of measurement of the pressure indicator. Is this to be done in quick succession appears all the values and the blood pressure monitor is ready for use.
Measurement:
As with all wrist blood pressure monitors is to keep the wrist at heart level, so that the measured values are not falsified necessary when measuring. The sleeve consists of a hard shell with Velcro. It can be managed two. These are marked by pictograms on the right side. After applying and pressing one of the icons of the measuring process starts. The compressor starts first short quite loud and then it goes on very quietly. The operation appears in this Wrist Blood Pressure Monitor vice versa than other of its kind to be. I know it so that only the cuff inflated to about 180, and then the air is released slowly. From the onset of heart sounds is measured. Here the unit is pumping slowly to 180 and when it has reached this value is final and the air is discharged. Apparently the device is oriented in mind, when the heartbeat stop. A measurement takes about 30 to 40 seconds. After the measurement of systolic, diastolic blood pressure and the Pulsfreuquenz is displayed. The displayed data is stored and can be accessed through the MEM button. The memory includes per person per 60 memory locations. The date and time (if set properly) is stored with the memory. On the left edge, there is a scale with a classification green-yellow-orange and red area. This should be possible a first classification of the measured values. But since the boundaries are dependent on the age, sex and country (other requirements), you should evaluate the results rather together with the treating physician.
Features
The blood pressure monitor has an indicator for an irregular heartbeat. There is also a surge in the display when the measurement is distorted by collisions. Under certain conditions, error messages are displayed as code whose meaning is explained in the manual.
When removing the batteries, the clock and possibly the date must be readjusted. The stored measurements are preserved.
Accuracy:
The absolute accuracy can probably only be determined under test conditions with calibrated reference instruments. In several comparative measurements with my other wrist sphygmomanometer (Boso medistar S with Stiftung Warentest Good) were very similar values displayed.
Conclusion:
You get a very handy, easy-to-use blood pressure monitor with a very easy to read display. The only complaint on my part would be the lack of storage for travel and storage at home. Sorry, no will be there and so you have to use for putting away the original box, however, which consists only of cardboard and can protect the device z. B. not well in a travel bag.
