What is blood pressure?
Blood pressure is the pressure created in the blood vessels by each heartbeat. When the heart contracts (systole) and pumps blood into the arteries, it brings about a rise in pressure. The highest value is known as the systolic pressure and is the first value to be measured. When the cardiac muscle relaxes to take in fresh blood, the pressure in the arteries also falls. Once the arteries are relaxed, a second reading is taken – the diastolic pressure.
How is blood pressure measured?
The medicine BU 514 is a blood pressure unit which is used to measure blood pressure at the upper arm. The measurement is carried out by a microprocessor, which, via a pressure sensor, measures the vibrations resulting from the inflation and deflation of the cuff over the artery.
Blood pressure classification
- Low blood pressure: systolic <100 diastolic <60
- Normal blood pressure: (green display area B8)
- systolic 100 139 diastolic 60 89
- Forms of hypertension: (yellow display area 18)
- Mild hypertension: systolic 140 – 159 diastolic 90 – 99
- Moderate hypertension: (orange display area 18)
- systolic 160 – 179 diastolic 100 – 109
- Severe hypertension: (red display area 18)
- systolic ≥ 180 diastolic ≥ 110
WARNING: Blood pressure that is too low represents just as great a health risk as blood pressure that is too high! Fits of dizziness may lead to dangerous situations arising (e.g. on stairs or in traffic)
Influencing and evaluating readings
- Measure your blood pressure several times, then record and compare the results. Do not draw any conclusions from a single reading.
- Your blood pressure readings should always be evaluated by a doctor who is also familiar with your personal medical history. When using the unit regularly and recording the values for your doctor, you should visit the doctor from time to time to keep him updated.
- When taking readings, remember that the daily values are influenced by several factors. Smoking, consumption of alcohol, drugs and physical exertion influence the measured values in various ways.
- Measure your blood pressure before meals.
- Before taking readings, allow yourself at least 5-10 minutes rest.
- If the systolic and diastolic readings seem unusual (too high or too low) on several occasions, despite correct use of the unit, please inform your doctor. This also applies to the rare occasions when an irregular or very weak pulse prevents you from taking readings.
Starting up
Insert/replace batteries
You must insert the batteries provided before you can use your unit. The lid of battery compartment 6 is located on the underside of the unit.

Fitting the cuff
- Push the end piece of the air tube 7 into the hole on the left side of the unit prior to use.
- Slide the open end of the cuff through the metal bracket so that the Velcro fastener is on the outside and it becomes a cylindrical form (Fig.1). Slide the cuff over your left upper arm.
- Position the air hose in the middle of your arm in line with your middle finger (Fig.2) (a). The lower edge of the cuff should be 2 – 3 cm above the crease of the elbow. (b). Pull the cuff tight and close the Velcro fastener. (c).
- Measure the pulse on your bare arm.
- Only position the cuff on the right arm if it cannot be used on the left arm. Always carry out measurements on the same arm.
- Correct measuring position for sitting (Fig.3).
Taking a blood pressure measurement
After the cuff has been appropriately positioned,the measurement can begin
- Switch the unit on by pressing the START/STOP button 4.
- If the START/STOP button 4 is pressed, two short beeps are heard and all display characters are shown (display test). This test can be used to check that the display is indicating properly and in full.
- The unit is ready for measurement and the number 0 flashes for 2 seconds. It automatically inflates the cuff slowly in order to measure your blood pressure. The rising pressure in the cuff is shown on the display.
- The unit inflates the cuff until sufficient pressure has built up for measurement. Then the unit slowly releases air from the cuff and carries out the measurement. When the device detects the signal, the heart symbol on the display starts to flash, you can hear the beep for every heartbeat once the heartbeat signal is detected.
- When the measurement is finished, you can hear a long beep and the cuff is deflated completely. The systolic and diastolic blood pressure and the pulse value with the pulse symbol appear on the display 8. The blood pressure indicator flashes next to the relevant colored bar depending on the blood pressure classification. If the unit has detected an irregular heartbeat, the display also flashes.
WARNING: Do not take any therapeutic measures on the basis of a self- measurement. Never alter the dose of medicine prescribed by a doctor.
- The readings are automatically saved in the selected memory ( or ). Up to 90 measured values with date and time can be stored in each memory.
- The measurement readings remain on the display. The unit switches off automatically after approx. 3 minutes if no buttons are pressed. The unit may also be switched off using the START/STOP button 4.
Discontinuing a measurement
If it is necessary to interrupt a blood pressure measurement for any reason (eg. the patient feels unwell) the START/STOP button 4 can be pressed at any time. The device immediately decreases the cuff pressure automatically.
Displaying stored values
This unit features 2 separate memories, each with a capacity of 90 memory slots. Results are automatically stored in the memory selected by the user. Press the MEM button 3 when power off, to call up the measured values stored. All values average appear on the display. Pressing the MEM button 3 again, the last measurement value will be shown. Repeatedly pressing the MEM button 3 displays the respective values measured previously. If you have reached the final entry and do not press a button, the unit automatically switches itself off after approximately 120 seconds in memory recall mode. Memory recall mode can be exited at any time by pressing the START/STOP button 4 , which will also switch the unit off. The oldest value is deleted if 90 measured values have been stored in the memory and a new value is saved.
Deleting stored values
If you are sure that you want to permanently remove all stored memories, press the SET button 5 for 7 times until CL appears when the power is off. Press the START/STOP button 4 , CL will flash 3 times to clear all the memories. After this press MEM buttons 3 , M, and “no” will be shown on the display which means that no memory in store.
